Vibrating string experiment

A crate of mass 500kg is raised to a height of 10ft from the floor. What is the GPE (Gravitational Potential Energy) it has acquired with respect to the ground.

At an instant when the displacement is equal to a/2, what fraction of the total energy of the system is potential?

Two waves have the same wavelength and frequency. how do their speeds compare?

at time t = 0, a 3.0 kg particle with velocity v = (5.0 m/s) i - (6.0 m/s) j is at x = 3.0 m, y = 8.0m. it is pulled by a 7.0 N force in the negative x direction.

Which statement correctly distinguishes between mechanical and electromagnetic waves? Electromagnetic waves carry energy through matter; mechanical waves carry energy through space.

Which EM wave is about the size of humans?

Describe how the Catapult works?

Newton's third law of motion states that the force pair acting on different objects consist of two forces that

While working on her science fair project Venus connected a battery to a circuit that contained a light bulb. Venus decided to change the light bulb to a higher resistance, but she wanted to keep the current the same.
