A capacitor acquires a charge of 0.003 C when connected across a 30-V battery. Its capacitance is

1) how does reflection differ from diffraction? A.) reflection is the only process in which the wave does not continue moving forward. B.) reflection is the only process that involves a change in the wave C.

A professional baseball player can pitch a baseball with a velocity of 44.7m/s towards home plate. If a baseball weighs 1.4 N, how much momentum does it have when it hits the catcher units

What's the unit of work

Glacial episodes are an example of

Ball A has a mass of 0.200 kilograms. Ball A, traveling at a velocity of 2 meters/second in the + x direction, hits a stationary ball B of the same mass. After the collision, ball B bounces off at a positive angle with respect to the + x-direction.

10. If the wavelength of the light is decreased, the width of the central maximum in the diffraction pattern will B) increase A) decrease C) remain the same

Materials with a density__water will float in water

A 0.5 kg ball is thrown horizontally towards a wall with a speed of 10 m/s. The initial velocity is chosen to be the positive x - direction for this question.
