Suppose a slide similar to der stuka is 35.0 m high, but is a straight slope, inclined at 45.0° with respect to the horizontal. (a) find the speed of a 60.0-kg woman at the bottom of the slide, assuming no friction. (b) if the woman has a speed of 20.0 m/s at the bottom, find the change in mechanical energy due to friction and (c) the magni- tude of the force of friction, assumed constant.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles

How will the system respond to a temperature increase?
