The sign of δethδethdeltae_{th} as the system of ideal gas goes from point a to point b on the graph is positive, as the graph of an ideal gas is a straight line which passes through the origin and has a positive slope.

If we are given the graph of an ideal gas, it will be represented as a straight line in the pressure-volume diagram and has a positive slope (since pressure is proportional to the number of molecules in the container).

The internal energy of an ideal gas is directly proportional to its temperature, which means that the value of δethδethdeltae_{th} is also proportional to temperature. Since the slope of the graph is positive, the temperature also increases, and the change in internal energy is positive (since δethδethdeltae_{th} is proportional to temperature).

Therefore, the sign of δethδethdeltae_{th} as the system of ideal gas goes from point a to point b on the graph is positive. An ideal gas undergoes isothermal expansion, that is, the temperature is kept constant while the volume is increased. According to the ideal gas law, the pressure is inversely proportional to the volume, which means that the pressure decreases as the volume increases.

the acceleration of the mass is 0.7212 m/s^2.

To find the acceleration of the mass, we need to first determine the net force acting on it. We can do this by using vector addition to add the two forces together.

Using the Pythagorean theorem, we can find the magnitude of the diagonal force:

sqrt[\((15N)^{2}\) + \((10N)^{2}\)] = sqrt[225 + 100] = sqrt(325) = 18.03 N

The direction of this force can be found using the inverse tangent function:

theta =\(tan^{-1}(10.0N/15.0N)\) = 33.69 degrees north of east

We can now use vector addition to find the net force on the mass:

F_net = sqrt[\((15N)^{2}\) + \((10N)^{2}\)] = 18.03 N, at an angle of 33.69 degrees north of east

To find the acceleration of the mass, we can use Newton's second law, which states that the net force acting on an object is equal to its mass times its acceleration:

F_net = ma

Solving for the acceleration, we get:

a = F_net / m = 18.03 N / 25.0 kg = 0.7212 m/s^2

Therefore, the acceleration of the mass is 0.7212 m/s^2.

The magnitude of the average force applied by the floor on the ball is 96 Newtons.

To solve this problem, we can use the principle of conservation of energy, which states that the total energy in a system remains constant if there are no external forces acting on it.

Initially, the ball has gravitational potential energy due to its position above the ground.

As it falls, this potential energy is converted into kinetic energy. Just before it hits the ground, all of the potential energy has been converted into kinetic energy.

At this point, the kinetic energy of the ball is given by:

KE = (1/2)mv^2

where m is the mass of the ball and v is its speed.

Substituting the given values, we get:

KE = (1/2) x 3 kg x (4 m/s)^2 = 24 J

When the ball hits the ground, it comes to a stop and all of its kinetic energy is transferred to the floor. Then, when it rebounds, this energy is transferred back to the ball.

Since the ball is in contact with the floor for 0.5 seconds, we can use the following equation to find the average force applied by the floor on the ball:

F = Δp/Δt

where Δp is the change in momentum of the ball and Δt is the time interval over which this change occurs.

The change in momentum of the ball is given by:

Δp = 2mv - (-2mv) = 4mv

where the negative sign indicates that the direction of motion is reversed.

Substituting the given values, we get:

Δp = 4 x 3 kg x 4 m/s = 48 kg m/s

Δt is given as 0.5 seconds.

Substituting these values into the equation for force, we get:

F = Δp/Δt = (48 kg m/s)/(0.5 s) = 96 N

Answer:

15 units NE

Explanation:

Assuming the coordinate plane is a compass with N being the positive y-axis, we can use the Pythagorean theorem to find the magnitude of the vector. Since the vector is going up by 12 and right by 9 at the same time, it should form a diagonal line, aka the hypotenuse of a triangle. This triangle has both of its leg units as 12, and 9. Pythagorean theorem states that a^2 + b^2 = c^2, that is both of their legs squared is the hypotenuse of the triangle squared. 12^2 + 9^2 = c^2. c = 15. Now that we know the magnitude, let's go back to the quadrants as the compass. Since both units are positive, the vector goes in the positive direction on both sides, which is Quadrant 1. North and East would be the appropriate say for the vector's direction, thus the vector's direction will be 15 units North East.

The passenger's weight before the elevator starts moving is

approximately 6200 N.

In order to determine the passenger's weight before the elevator starts moving, we need to consider the forces acting on the passenger. When the elevator is stationary or moving at a constant speed, the forces acting on the passenger are balanced. This means that the force of gravity pulling the passenger downward is equal to the normal force exerted by the floor pushing the passenger upward.

When the elevator is stationary, the normal force exerted by the floor is equal to the passenger's weight. Therefore, we can calculate the weight of the passenger by considering the force of gravity acting on the passenger.

The weight of an object can be calculated using the equation:

Weight = mass × gravitational acceleration

The mass of the passenger is not given in the question, but since we are asked to provide the answer using two significant figures, we can assume that the passenger's mass is approximately 62 kg (using two significant figures).

The gravitational acceleration on Earth is approximately 9.8 m/s². Using the equation mentioned earlier, we can calculate the weight of the passenger:

Weight = 62 kg × 9.8 m/s² = 607.6 N

Rounding this value to two significant figures gives us the main answer of approximately 6200 N.

A lens with a diameter of 100 cm has a theoretical resolution limit of about 0.011 arcseconds for visible light observations.

The resolution of a telescope or lens is determined by its aperture size and the wavelength of the observed light. The theoretical limit of resolution is given by the Rayleigh criterion, which states that the smallest angular separation between two objects that can be resolved is approximately equal to the wavelength of the observed light divided by the aperture diameter.

For a lens of diameter 100 cm, the resolution can be estimated as:

resolution = wavelength / aperture diameter

Assuming a typical visible light arcseconds of 500 nm (5 x 10^-7 m), we can convert this to arcseconds using the formula:

1 radian = 206265 arcseconds

Therefore, the resolution in arcseconds is:

resolution = (wavelength / aperture diameter) * (180 / pi) * 3600 * 206265

resolution = (5 x 10^-7 m / 100 m) * (180 / pi) * 3600 * 206265

resolution ≈ 0.011 arcseconds

So a lens with a diameter of 100 cm has a theoretical resolution limit of about 0.011 arcseconds for visible light observations.

When two charged particles, such as electrons, are discharged, their acceleration depends on their charge and the distance between them.

In mechanics, acceleration is defined as the rate of change of an object's velocity with respect to time. Vector quantities are accelerations. The orientation of an object's acceleration is determined by the orientation of its net force. The rate of change of velocity is defined as acceleration. Acceleration usually indicates that the speed is changing, however this is not always the case. When an item goes on a circular course with a constant speed, it is still accelerating since its velocity direction changes. An object's velocity might fluctuate due to an increase or decrease in speed or a change in direction of motion. A falling apple and the moon orbiting the earth are two instances of acceleration.

The producer of refrigerator compressors needs to determine the number of kanbans required for implementing a just-in-time production line to meet the demand for 150 compressors per day from a neighboring appliance manufacturer.

To calculate the number of kanbans required, we need to consider the production lead time, safety stock factor, and optimal production quantity. The production lead time is 5 days, which means that it takes 5 days to produce a batch of compressors once the production process starts.

The safety stock factor is 17%, indicating that the producer wants to maintain an additional 17% of the daily demand as safety stock to mitigate any unforeseen fluctuations. The optimal production quantity is 95 units, which is the batch size that minimizes setup costs.

To determine the number of kanbans, we first need to calculate the total demand during the production lead time. Since the demand is 150 compressors per day and the lead time is 5 days, the total demand during the lead time is 150 compressors/day * 5 days = 750 compressors. Adding the safety stock, the total demand becomes 750 compressors + (17% * 150 compressors) = 750 compressors + 25.5 compressors = 775.5 compressors.

Next, we divide the total demand by the optimal production quantity to get the number of kanbans required. The number of kanbans is calculated as 775.5 compressors / 95 compressors per kanban = 8.16 kanbans. Since we cannot have a fraction of a kanban, we round up to the nearest whole number. Therefore, the producer of compressors requires 9 kanbans to meet the demand of 150 compressors per day from the neighboring appliance manufacturer.

The statement "If we  place a non polar molecule in an electric field" is  true  because  a non polar molecule will not experience a significant force or reorientation in an electric field because it lacks a permanent electric dipole moment.

Non polar molecules have a symmetrical distribution of charge, meaning the positive and negative charges are evenly distributed. In an electric field, the electric forces acting on individual atoms or charges within the molecule will cancel each other out due to the symmetry.

Since the net force on the molecule is zero, it will not accelerate or move in response to the electric field. Similarly, there will be no net torque on the molecule, meaning it will not rotate or align itself with the electric field.

In summary, non polar molecules do not interact strongly with electric fields due to their balanced charge distribution, resulting in no net force or torque being exerted on them.
