Why do objects accelerate when dropped on Earth? A) The force of Earth's gravity continuously acts on the object making it go faster over time. B) Objects in motion always accelerate. C) For every action, there is an equal and opposite reaction.

What happens to an object if the forces acting on it are unbalanced?

A 92-kg astronaut and a 2000-kg satellite are at rest relative to a space station. the astronaut pushes on the satellite, giving it a speed of 0.14 m/s directly away from the station.

How to calculate wavelength in m when you know the frequency?

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
