Which waves are electromagnetic and can travel through a vacuum? Light and heat waves
Longitudinal and transverse waves
Sound waves
Surface waves

The equation that describes a transverse wave on a string is y = (0.0120 m)sin[(927 rad/s)t - (3.00 rad/m)x] where y is the displacement of a string particle and x is the position of the particle on the string. the wave is traveling in the +x direction. what is the speed v of the wave?

Suppose while hauling rocks, you accidentally drop one. it breaks apart in flat, planar sections. what type of rock did you just drop? 20 points

Based on this activity, is kinetic energy always transformed into potential energy?
