A wave is sent along the first rope transmitting a power of 14.7 W. It has a wavelength of 9.20 cm and velocity of 10.39 m/s The linear density of the rope is 591 g/m. What is the amplitude of the wave

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
