The graph below shows the velocity distribution for a gas at 400 k. which of the following graphs correspond to the same gas at 800 k?

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)

Which change would make the diagram correct?
