At time t1 = 2.00 s, the acceleration of a particle in counterclockwise circular motion is (7.00 m/s^2) i + (8.00 m/s^2) j. It moves at constant speed. At time t2 = 5.00 s (3/4 of a revolution later), its acceleration is (8.00 m/s^2) i + (-7.00 m/s^2) j. What is the radius of the path taken by the particle?

Answers

Answer 1

The magnitude of the change in velocity is approximately 38.81 m/s, and the direction is approximately -75.96°.

Let's denote the initial velocity at \(t_1\) as \(v_1\) and the final velocity at \(t_2\) as \(v_2\).

To find \(v_1\), we integrate \(a_1\) with respect to time from 0 to \(t_1\):

\(v_1\) = ∫(a1) dt = ∫((\(7.00 m/s^2\))i + (\(8.00 m/s^2\))j) dt

Integrating with respect to time:

\(v_1 = (7.00 m/s^2)(t_1) i + (8.00 m/s^2)(t_1) j\)

Substituting the value of \(t_1\):

\(v_1 = (7.00 m/s^2)(2.00 s) i + (8.00 m/s^2)(2.00 s) j \\v_1 = (14.00 m/s)i + (16.00 m/s)j\)

Similarly, to find \(v_2\), we integrate \(a_2\) with respect to time from \(t_1\) to \(t_2\):

\(v_2\) = ∫(\(a_2\)) dt = ∫((\(8.00 m/s^2\))i + (-\(7.00 m/s^2\))j) dt

Integrating with respect to time:

\(v_2 = (8.00 m/s^2)(t_2 - t_1) i + (-7.00 m/s^2)(t_2 - t_1) j\)

Substituting the values :

\(v_2 = (8.00 m/s^2)(5.00 s - 2.00 s) i + (-7.00 m/s^2)(5.00 s - 2.00 s) j\)

\(v_2 = (8.00 m/s^2)(3.00 s) i + (-7.00 m/s^2)(3.00 s) j\)

\(v_2 = (24.00 m/s)i + (-21.00 m/s)j\)

Now, we can calculate the change in velocity, Δv, by subtracting \(v_1\) from \(v_2\):

Δv =\(v_2 - v_1\)

Δv = (24.00 m/s)i + (-21.00 m/s)j - (14.00 m/s)i - (16.00 m/s)j

Δv = (24.00 m/s - 14.00 m/s)i + (-21.00 m/s - 16.00 m/s)j

Δv = (10.00 m/s)i + (-37.00 m/s)j

The magnitude of the change in velocity, |Δv|, is given by:

|Δv| = \(\sqrt{((10.00 m/s)^2 + (-37.00 m/s)^2)\)

Calculating this, we find:

|Δv| ≈ 38.81 m/s

The direction of the change in velocity can be determined using the arctan function:

θ = arctan((-37.00 m/s) / (10.00 m/s))

Calculating this, we find:

θ ≈ -75.96°

An airplane passenger carries a 215-N suitcase up the stairs, a

displacement of 4. 20 m vertically and 4. 60 m horizontally.

A) How much work does the passenger do on the suitcase?

B) The same carries the same suitcase back down the same set of stairs. How much work does the passenger do on the suitcase to carry it down the stairs?

Answers

The total work done by the passenger on the suitcase is 1641J and the amount of work the passenger does on the suitcase to carry it down the stairs will also be 1641J.

A) The work done by the passenger on the suitcase can be calculated using the formula Work = Force x Distance. In this case, the force is the weight of the suitcase, which is 215N, and the distance is the total displacement of the stairs, which is 4.20 m vertically and 4.60 m horizontally. The total work done on the suitcase is thus

215N x (4.20 m + 4.60 m) = 1641 J.

B) The work done by the passenger on the suitcase to carry it back down the stairs is the same as when they carried it up the stairs:

=1641 J.

This is because the work done depends only on the force and distance, not on whether the motion is up or down. The force and distance are the same in this case.

2) The electrostatic force if the charge on q1, doubled is  5.624 N.

3) The electrostatic force if the distance between charges, doubled is 0.703 N

What is electrostatic force?

The electrostatic force F between two charged objects placed distance apart is directly proportional to the product of the magnitude of charges and inversely proportional to the square of the distance between them.

F = kq₁q₂/d²

where coulomb constant, k = 9 x 10⁹ N.m²/C²

1) Given is a point charge (q1) has a magnitude of 3.0 x10⁻⁶ C. A second charge (q2) has a magnitude of -1.5 x10⁻⁶ C and is located 0.12 m from the first charge.

F =  9 x 10⁹x 3.0 x10⁻⁶x1.5 x10⁻⁶ / (0.12)²

F = 2.812 N

Thus, the electrostatic force each charge exerts on the other is 2.812 N.

2) When the charge q1 is doubled, new force will be

F' =  9 x 10⁹x (2 x3.0 x10⁻⁶)x1.5 x10⁻⁶ / (0.12)²

F = 2 x F

F' =2 x2.812 N

F' = 5.624 N

Thus, the electrostatic force if the charge on q1, doubled is  5.624 N.

3) If the distance between them is doubled without altering their charges, the force between them becomes

New force will be

F'' =  9 x 10⁹x 3.0 x10⁻⁶x1.5 x10⁻⁶ / (2 x 0.12)²

F'' = F/4

F'' =2.812 /4

F'' = 0.703 N

Thus, the electrostatic force if the distance between charges, doubled is 0.703 N

What is the efficency of a sertain engine whose hot resevoir is 700 celsius and the cold reservoir is 230 celsius

Answers

The efficiency of a certain engine can be determined using the Carnot Cycle equation. The efficiency of an engine is proportional to the difference in temperature between the hot reservoir and the cold reservoir.

The efficiency can be calculated using the following formula:

η = (Th - Tc) / ThWhere,η = efficiency of the engine

Th = temperature of the hot reservoir

Tc = temperature of the cold reservoir

Given that the temperature of the hot reservoir is 700°C and the temperature of the cold reservoir is 230°C.

Therefore,η = (700 - 230) / 700η = 0.67The efficiency of the engine is 0.67 or 67%. In other words, only 67% of the heat energy is converted into mechanical energy while the remaining 33% is lost as waste heat.

Susan makes the following entry in her notebook: “On Friday we were given a blue liquid in a shallow container. We placed it on the windowsill over the weekend. On Monday morning, there was no liquid left, but the dish had some solid blue stuff in it.”

a. Was the blue liquid in the dish a heterogenous mixture, a solution, or a pure substance? Explain your choice.

b. Write a few sentences about what you think happened in the dish.

Answers

Answer:

Explanation:

a. From the information provided in the question, the blue liquid is a solution. This is because a solution is a type of homogeneous mixture (that has an evenly distributed solute in a solvent) which is the reason the liquid was said to be blue (and not immiscible blue solid in a liquid) but after been exposed to heat became just a blue solid. Typically, a solution has a solute and a solvent (combined), the solute here is the blue solid while the solvent is the liquid that made the combination a liquid.

b. Since the dish containing the liquid was placed on a windowsill, it can be assumed that the dish was subjected to heat from the sun which caused the liquid (in the solution) to evaporate after exposure to the heat from the sun (over the weekend) leaving the blue solid solute (of the solution) to remain in the dish. This can be referred to as evaporation to dryness in separation techniques (if the goal was to intentionally separate the solid solute from the liquid solvent).

A ball of 5.2 kg is swung around on a rope with a radius 0.86 meters. If the ball is traveling at 1.8 m/s, what is its angular momentum

Answers

The angular momentum of the ball that has a mass of 5.2 kg and is swung around a rope with a radius of 0.86 meters at a speed of 1.8 m/s is approximately 7.24 kg m²/s.

We know that angular momentum is the product of an object's rotational inertia and rotational speed or angular velocity. The equation for angular momentum is:L = IωWhere L is angular momentum, I is rotational inertia, and ω is angular velocity. Since the ball is moving in a circular path, we need to use the formula for rotational inertia of a point mass: I = mr², where m is the mass of the ball and r is the radius of the circle.The angular velocity ω can be calculated from the linear speed v using the formula v = rω, which gives ω = v/r. Substituting these values into the equation for angular momentum, we get:L = Iω = (mr²)(v/r) L = 5.2 kg x 0.86 m x 1.8 m/s = 7.24 kg m²/sTherefore, the angular momentum of the ball is approximately 7.24 kg m²/s.

The second step of the force field model is about the execution of the change. The key is developing new strategies, tactics, or action plans that are aligned with the proposed change.

Once the driving and restraining forces have been identified in the first step of the force field analysis, the next step is to develop strategies or action plans that can strengthen the driving forces or weaken the restraining forces. These strategies should be designed in a way that supports and facilitates the desired change.

There is no specific calculation involved in this step. Instead, it requires careful analysis and planning based on the identified driving and restraining forces. The strategies or action plans should be tailored to address the specific factors influencing the change and should be actionable and realistic.

The second step of the force field model is crucial for the successful execution of the change. By developing new strategies, tactics, or action plans that are aligned with the proposed change, organizations can effectively navigate the forces at play and increase the likelihood of achieving the desired outcome. It is important to consider the various driving and restraining forces identified in the previous step and create actionable plans that mitigate the restraining forces while reinforcing the driving forces.

What is the distance from concave mirror?

a) According to the New Cartesian sign convention, the object distance (u) is -60 cm and the image distance (v) is -40 cm.

b) To find the focal length of the mirror, we can use the lens equation: 1/f = 1/u + 1/v. Substituting the values for u and v, we get: 1/f = 1/-60 + 1/-40 = -1/60 + 3/120 = -1/60 + 1/40 = -1/24 cm. Therefore, the focal length of the mirror is -24 cm.

c) To find the magnification, we use the formula: Magnification (M) = -v/u. Substituting the values for u and v, we get: M = -(-40)/(-60) = 2/3. Therefore, the magnification of the image is 2/3.

Answers

The aforementioned circumstances can result in the production of 0.119 moles of ammonia (NH3).

We must utilize the ideal gas law and the stoichiometry of the balanced chemical equation for the reaction between hydrogen (H2) and nitrogen (N2) to make ammonia in order to determine how many moles of ammonia (NH3) were produced.

Let's begin by formulating the reaction's balanced equation:

3H₂ + N₂ → 2NH₃

We can see from the equation that we produce 2 moles of ammonia for every 3 moles of hydrogen. As a result, the molar ratio of ammonia to hydrogen is 2:3.

We must convert the supplied parameters of 4.0 liters of hydrogen at 50.0 °C and 1.2 atm of pressure into moles in order to use the ideal gas law. The ideal gas law and the molar volume of an ideal gas at standard temperature and pressure (STP) may be combined using the equation shown below:

PV = nRT

Where:

The temperature must first be converted from Celsius to Kelvin:

T(K) = T(°C) + 273.15

T(K) = 50.0°C + 273.15 = 323.15 K

To solve for the number of moles (n), we may now rearrange the ideal gas law equation as follows:

n = PV / RT

n = (1.2 atm) * (4.0 L) / (0.0821 L·atm/(mol·K) * 323.15 K) ≈ 0.179 mol

Since ammonia and hydrogen have a 2:3 molar ratio, we can calculate the amount of ammonia created by multiplying (2/3) * 0.179 mol by 0.119 mol.

As a result, the circumstances allow for the production of 0.119 moles of ammonia.

Answers

The angle above the surface of the water that the sunlight hits is approximately 48.6 degrees.

To answer your question, we need to find the angle of incidence for sunlight as it enters the water. We'll use Snell's Law, which states:

n1 * sin(θ1) = n2 * sin(θ2)

Here, n1 is the refractive index of air (approximately 1), n2 is the refractive index of water (approximately 1.33), θ1 is the angle of incidence we want to find, and θ2 is the angle of refraction (74 degrees below the surface).

1 * sin(θ1) = 1.33 * sin(74°)
sin(θ1) = 1.33 * sin(74°)

Now, we'll solve for θ1:

θ1 = arcsin(1.33 * sin(74°))

After calculating, we get:

θ1 ≈ 48.6°

So, the sunlight hits the surface of the water at an angle of approximately 48.6 degrees above the surface.
