A baseball with a mass of m = 0.19 kg is pushed down onto the top of a vertical spring compressing the spring a distance of d = 0.16 meters spring constant of the spring is k = 650 N/m gravitational potential energy is 0 What is the ball’s velocity at half of the maximum height relative to the equilibrium point?

Hey student studies gravity using objects that have the same mass which two objects have the greatest gravitational force acting between them a. 100kg 1.0m 100kg b. 100kg 2.0m 100kg c. 100kg 2.0m 100kg big d. 100kg big 3.0m 100kg big

What is a subatomic particle with a negative charge and very little mass?

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
