Given that the small piston has a radius of 0.0330 meters^2 and the large piston has a radius of 4.00 meters^2.
(
a. what force will the large piston provide if the small piston is pushed down with a force of 17.0 n? .
(
b. if the small piston is slowly depressed a distance of y1 = 0.300 m, by how much will the large piston rise?
(
c. how much work was done in pushing down the small piston? how much work was done by the large piston?

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
