a toy rotates at a constant 5rev/min. is its angular acceleration positive, negative, or zero?
Answers
Answer:
Its angular acceleration is zero.
Explanation:
If the angular velocity of an object (in this case the toy) is constant, then its angular acceleration will be zero. Why? Because angular acceleration is the time rate change of angular velocity. Since there is no change, this brings the answer to zero.
i) A distillation column is fitted with a condenser that has 180 vertical tubes of 50 mm inner diameter, for separating benzene from a mixture of chlorobenzenes. The vapour and liquid flow rates are 8,000 kg/h, 7,000 kg/h respectively. The condenser operates at the pressure of 1 bar (absolute). Using the Hall-Taylor criterion for flooding, determine whether the tubes are likely to flood. At its boiling point, the densities of liquid and vapour phase benzene are: Properties of liquid and vapour
rhoL= 840 kg m-3
rhoL= 2.7 kg m-3
ii) Explain why flooding should be controlled in condensers.
Answers
The Hall-Taylor criterion for flooding can be given by the expression, y = 0.074 [ (ρL /ρV) (σ /ρL gD) ]0.25
where, y is the maximum permissible liquid flow rate per unit cross-sectional area,
ρL is the density of the liquid,
ρV is the density of the vapour,
σ is the surface tension of the liquid,
D is the diameter of the tube,
and g is the gravitational acceleration.
The given details are,
Vapour flow rate, Q = 8,000 kg/h
Liquid flow rate, L = 7,000 kg/h
Pressure, P = 1 bar
Inner diameter of the tube, d = 50 mm
Boiling point of benzene, ρL = 840 kg/m³
Density of the vapour phase benzene, ρV = 2.7 kg/m³
Surface tension of benzene, σ = 0.0285 N/m
The gravitational acceleration, g = 9.81 m/s²
Diameter of the tube, D = 50 mm = 0.05 m
As the given parameters are in kg/h, we need to convert them into kg/s.
To convert kg/h to kg/s, we need to divide the given values by 3600 kg/h = 8,000 / 3600 = 2.22 kg/s
Liquid flow rate, L = 7,000 / 3600 = 1.94 kg/s
From the given details,ρL = 840 kg/m³ρV = 2.7 kg/m³σ = 0.0285 N/mg = 9.81 m/s²D = 0.05 m
Substituting these values in the above equation, the Hall-Taylor criterion for flooding can be given by,
y = 0.074 [ (840 / 2.7) (0.0285 / 840 × 9.81 × 0.05) ]0.25y = 0.0049 m³/s/m²
Now, the liquid flow rate per unit cross-sectional area is given by,L / A = y
where, A is the cross-sectional area of the tube.
As the tube is of 50 mm diameter, the cross-sectional area can be given by,
A = πD² / 4A = π (0.05)² / 4A = 1.963 × 10⁻⁴ m²
The maximum permissible liquid flow rate per unit cross-sectional area is given by,L / A = 0.0049L = 0.0049 × A
Thus, L = 0.0049 × 1.963 × 10⁻⁴L = 9.61 × 10⁻⁷ m³/s
The given liquid flow rate is, L = 1.94 kg/s = 0.00194 m³/s
The maximum permissible liquid flow rate per unit cross-sectional area, L / A = 9.61 × 10⁻⁷ m³/s
Thus, the tubes are not likely to flood as the maximum permissible liquid flow rate per unit cross-sectional area is more than the actual liquid flow rate per unit cross-sectional area.
Flooding should be controlled in condensers for the following reasons:
To prevent the condensers from becoming filled with liquid and to prevent the interference of liquid with the condensation process.
To prevent the flooding of liquid in the tubes that can result in inefficient operation, decreased output, and increased maintenance cost.
To prevent the liquid in the tubes from being entrained into the vapour and causing the contamination of downstream equipment.
To prevent the formation of a continuous film of liquid in the tubes that can result in the reduction of the heat transfer coefficient and increased resistance to vapour flow.
To avoid hydraulic problems that can cause the development of high pressure drops and uneven flow distribution, which can result in tube erosion, leakage, and other problems.

When is the photoelectric effect observed?
Answers
The photoelectric effect is observed when light interacts with matter, specifically when photons (particles of light) transfer their energy to electrons in an atom or a material. The correct answer is A. When an electric current results from light shining on a surface.
In the early 20th century, Albert Einstein provided a groundbreaking explanation of the photoelectric effect, which earned him the Nobel Prize in Physics in 1921. His work established the dual nature of light, both as a wave and as a particle (photon). Here's a detailed explanation of the photoelectric effect:
When light shines on a surface, it is composed of photons that carry energy. These photons interact with electrons in the material. The photoelectric effect occurs when photons transfer their energy to electrons, causing them to be emitted from the material.
The process can be described in several steps:
1. Absorption: When a photon with sufficient energy interacts with an electron in an atom or material, it can be absorbed. The energy of the photon is transferred to the electron, promoting it to a higher energy level or even releasing it from the atom.
2. Ejection: If the energy of the absorbed photon is greater than or equal to the binding energy of the electron (also known as the work function), the electron can be ejected from the material. The work function represents the minimum energy required to remove an electron from the material's surface.
3. Electron emission: The ejected electron can now contribute to the formation of an electric current. If there is a conducting material connected to the surface, the released electron can move through the material, resulting in the flow of electric charge.
The photoelectric effect is not observed when light acts solely as a wave (option B). While light does exhibit wave-like properties, such as interference and diffraction, these phenomena do not directly involve the transfer of energy from photons to electrons.
Option C, "When an electric current causes light to be produced," does not accurately describe the photoelectric effect. The photoelectric effect involves the emission of electrons due to the interaction of light with matter, but it does not directly produce light as a result of an electric current.
Option D, "Any time an electric current is produced," is a broad statement that encompasses various phenomena beyond the photoelectric effect. Electric currents can be produced in various ways, such as through the flow of charged particles or the movement of electrons in a conductor. The photoelectric effect is a specific phenomenon that occurs when light interacts with matter and results in the emission of electrons.
To summarize, the photoelectric effect is observed when light shines on a surface, and the energy of photons is transferred to electrons, leading to their emission from the material. This emission of electrons can result in the formation of an electric current.

LIGO detect gravitational waves by: looks for changes in the distance between sets of mirrors located at right angles to each other, uses lasers in an interferometer, and looks for the same signal nearly simultaneously in two different detectors located a few miles apart.
So, the correct answer is A, B and D.
LIGO, or the Laser Interferometer Gravitational-Wave Observatory, detects gravitational waves using lasers in an interferometer.
It does this by looking for changes in the distance between sets of mirrors located at right angles to each other.
When a gravitational wave passes through, it causes the mirrors to move slightly, which can be detected by the interference pattern of the laser beams. LIGO also looks for the same signal nearly simultaneously in two different detectors located a few miles apart to confirm the detection.
By detecting gravitational waves, LIGO allows us to study the universe in a new way, opening up opportunities for new discoveries and insights into the nature of space and time.

(a) radius = 13 cm and AB = 10cm
(b) radius = 11 cm and AB = 7.8cm
Answers
The perpendicular distance of the chord from(a) radius = 13 cm and AB = 10cm is 6 cm, (b) radius = 11 cm and AB = 7.8cm is 5.52 cm.
To find the perpendicular distance of a chord from the centre of a circle, we need to draw a perpendicular line from the centre to the chord and measure the length of this line.
Using the formula d = √\((r^2 - (AB/2)^2)\), where d is the perpendicular distance, r is the radius, and AB is the length of the chord, we can solve for the distance in each case.
(a) d = √\((13^2 - (10/2)^2)\)= √(169-25) = √144 = 12, so the perpendicular distance is 6 cm.
(b) d = √\((11^2 - (7.8/2)^2)\)= √(121-30.69) = √90.31 ≈ 9.50, so the perpendicular distance is 5.52 cm (rounded to two decimal places).

A. MR2/2
B. 2MR2/3
C. MR2
D. 3MR2/2
E. 7MR2/5
Answers
The moment of inertia of the cylinder about the horizontal axis parallel and tangent to the cylinder is 3MR²/2.
The moment of inertia (Icm) of the cylinder about its symmetrical axis is calculated using the formula MR^2/2, where M represents the mass of the cylinder and R represents its radius.
To find the moment of inertia of the cylinder about the axis parallel and tangent to the cylinder, we can use the parallel axis theorem. According to the parallel axis theorem, the moment of inertia about an axis parallel to and at a distance 'd' from the axis passing through the center of mass is given by:
I = Icm + Md^2
In this case, the axis of rotation is parallel and tangent to the cylinder, so the distance 'd' from the axis passing through the center of mass is equal to the radius 'R'. Substituting the values into the equation:
I = Icm + MR^2
I = MR^2/2 + MR^2
I = (1/2 + 1)MR^2
I = (3/2)MR^2
Therefore, the moment of inertia of the cylinder about the given axis is (3/2)MR^2.
The correct answer is (D) 3MR^2/2.

The motion of a particle is described by x= 10 sin2t + 8cos2t. Determine the period, amplitude and phase angle
Answers
If the motion of a particle is described by x=10 sin2t+8cos2t then the period , amplitude and phase angle will be:-
Period of the function is given by the reciprocal of the frequency, which is 1/2. Thus, the period is T = 2/1 = 2.
The amplitude of the function is given by the maximum value of the function minus the minimum value of the function. The maximum value of the function is 10 + 8 = 18 and the minimum value of the function is -10 + 8 = -2. Thus, the amplitude is A = 18 - (-2) = 20.
The phase angle is given by the angle between the x-axis and the line representing the function. The function is a combination of sine and cosine functions, so the phase angle is given by the angle between the x-axis and the line y = 10x + 8. The slope of this line is 10, so the phase angle is tan^-1(10) = 84.3 degrees.

why is it more difficult to start moving a heavy carton from rest than it is to keep pushing it with constant velocity?
Answers
It is more difficult to start moving a heavy carton from rest than it is to keep pushing it with constant velocity because of static friction.
Static friction refers to the resistance encountered when attempting to initiate the movement of two objects that are in contact with each other but not currently in motion relative to each other. When an object is at rest, the force of static friction acts in the opposite direction to any force applied to it.
In this case, the force applied to the carton is the force needed to start moving it from rest. The force of static friction is greater than the force applied to the carton, making it difficult to start moving the carton from rest.
Once the carton is moving with constant velocity, the force of static friction is no longer acting on it. The only force acting on the carton is the force that is applied to keep it moving at a constant velocity. This force is equal to the force of kinetic friction which is less than the force of static friction.
To summarize, the initial effort required to overcome the static friction between a heavy carton and its resting position is greater compared to the continuous force needed to maintain its constant velocity. The force of static friction is greater than the force applied to the carton, making it difficult to start moving the carton from rest.
Once the carton is moving with constant velocity, the force of static friction is no longer acting on it, and the only force acting on the carton is the force that is applied to keep it moving at a constant velocity.

Answers
By examining these factors, such as mean, variability, and bias, we can determine which student was better at estimating the mass of the objects.
To determine which student was better at estimating the mass of the objects, we need to compare the summary statistics of their estimates. Without specific summary statistics provided, we can consider the following factors:
1. Mean: Calculate the mean estimate for each student by summing up their estimates and dividing by the number of objects. Compare the mean estimates of Clare and Lin. The student with a mean estimate closer to the actual weight of 2,000 grams would be considered better at estimating the mass.
2. Variability: Consider the variability of the estimates for each student. Calculate the standard deviation or range of estimates for Clare and Lin. A smaller standard deviation or range indicates more consistent and accurate estimates, suggesting better estimation skills.
3. Bias: Check if there is any systematic bias in the estimates of either student. If one student consistently overestimates or underestimates the mass, it may indicate a tendency for inaccurate estimation.

μ = 0.4 move in the direction of a horizontal force
of 300N applied to it.
a). Calculate the
i). friction force
ii). acceleration of the body
b). Explain the result in aii).
Answers
Explanation:
a) i) Calculation of the friction force:
The friction force can be determined using the equation:
friction force = coefficient of friction * normal force
The normal force is equal to the weight of the object, which can be calculated as:
normal force = mass * gravitational acceleration
where the gravitational acceleration is approximately 9.8 m/s².
normal force = 75 kg * 9.8 m/s² = 735 N
friction force = 0.4 * 735 N = 294 N
ii) Calculation of the acceleration of the body:
Now, we can calculate the acceleration using Newton's second law:
net force = mass * acceleration
Since the applied force and the friction force act in opposite directions, the net force can be calculated as:
net force = applied force - friction force
net force = 300 N - 294 N = 6 N
mass = 75 kg
6 N = 75 kg * acceleration
acceleration = 6 N / 75 kg = 0.08 m/s²
b) Explanation:
In part (a), we calculated the friction force to be 294 N and the acceleration of the body to be 0.08 m/s². The positive acceleration indicates that the body is moving in the direction of the applied force.
The friction force opposes the motion of the body and acts in the opposite direction to the applied force. In this case, the applied force of 300 N is greater than the friction force of 294 N. As a result, the net force acting on the body is 6 N in the direction of the applied force.
The small net force of 6 N, compared to the body's mass of 75 kg, results in a relatively low acceleration of 0.08 m/s². This indicates that the body will accelerate slowly in the direction of the applied force due to the presence of friction.
Overall, the friction force and the resulting acceleration of the body are determined by the coefficient of friction (μ) and the mass of the object. In this case, the body experiences a relatively high friction force, leading to a small acceleration.

How high is the end of the treadmill raised?
a 0.71 m
0.46 m
0.54 m
0.62 m
Answers
The answer is 0.47 m, which is closest to the option (A) 0.71 m.
How to solve this problemFirst we can use trigonometry. The height of the end of the treadmill raised is the opposite side of the right triangle, and the length of the treadmill is the hypotenuse.
The angle of inclination is the angle between the height and the hypotenuse, so we can use the sine function to find the height:
sin(17°) = opposite/hypotenuse
The length of the treadmill is 1.75 m, so:
opposite = sin(17°) x 1.75 m
opposite = 0.472 m
Therefore, the height of the end of the treadmill raised is approximately 0.47 m.
So the answer is 0.47 m, which is closest to the option (a) 0.71 m.

The gravitational field acting on it will be the same for the both time of flight as it goes upward and as it coming downward and it will act on it in the same way. Hence, we will see that the orange is taking the same time as it is going upward and then it is coming downward, it will not experience any other significant force rathe than the gravitational force. rest of the forces like the air friction goes cancelled out as it will not be made a significant part on the orange. the only force that is acting on it continuously is the gravitational force. so we can consider that the juggler throws an orange vertically in the air. it will take the same time as that of it will take the time for ascend.

With these missions, scientists have been able to study the geology and morphology of Venus, including its thick atmosphere, which has made it difficult to observe the surface with visible light. Overall, the data collected from these missions has greatly improved our understanding of Venus and its unique topography.
