Mac and tosh stand 12 meters apart and demonstrate the motion of a transverse wave on a slinky. the wave can be described as having a vertical distance of 1.2 meters from a trough to a crest, a frequency of 2.7 hz, and a horizontal distance of 0.5 meters from a crest to the nearest trough. what is the amplitude, period, and wavelength and speed of such a wave.

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

During cooling, the kinetic energy of the molecules falls. why does this happen? a.the motion of the molecules increases. b. the motion of the molecules slows down. c.the van der waals forces between molecules decrease d. the forces of attraction between the molecules are overcome.
