An object in space is initially stationary relative to the Earth. Then, a force begins
acting on the object, starting with a force of O
N, and increasing at a uniform rate until the
magnitude of the force is 32 N after the force
has acted for 35 s. The body has a mass of
5 kg.
What is the speed of the object at 35 s?

Which atomic model was proposed as a result of j. j. thomson’s work?

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?

An atom that has gained or lost electrons is called an _
