When i wave a charged golf tube at the front of the classroom with a frequency of two oscillations per second, i produce an electromagnetic wave of frequency 2hz. what is the wavelength of this wave? (a) 6.7 × 10−9m (b) 1.5 × 108m (c) 3.0 × 108m (d) 6.0 × 108m

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?
