A bookshelf is 2m long, with supports at its end (p and q). A book weighing 10N is placed in the middle of the shelf. what are the upward forces?

Type the correct answer in the box. In the fishbowl, the glass, water, rocks, and plastic plants are in thermal equilibrium. This situation means the temperature of the rocks is °F.

The force is proportional to what measurement

A moving ball rolls into a stationary ball. the total momentum of both balls after the collision will be

A train's mass is 18181.81 kg. What is its weight?

A body of mass 20kg is set in motion by two forces 3N and 4N acting at right angles to each other, determine the magnitude of the acceleration

Gerry and Lena work in a modern physics laboratory and study nanotechnology, which is a new type of technology that allows control over individual particles as small as molecules or atoms.
