If the vector represents velocity this number represents the speed

A solid metal sphere of radius a = 2.5 cm has a net charge Qin = - 3 nC (1 nC = 10-9C). The sphere is surrounded by a concentric conducting spherical shell of inner radius b = 6 cm and outer radius c = 9 cm. The shell has a net charge Qout = + 2 nC.

What are waves such as transverse and electromagnetic

An 8.5 l tire is filled with 0.55 moles of gas at a temperature of 305 k. what is the pressure of the gas in the tire?

A single force acts on a particle-like object of mass m kg in such a way that the position of the object as a function of time is given by x = 3t - 4t2 + t3, with x in meters and t in seconds.

How would an unbalanced chemical equation convey misleading information about what took place during a chemical reaction?

A car rounds a 75-m radius curve at a constant speed of 18 m/s. a ball is suspended by a string from the ceiling the car and moves with the car. the angle between the string and the vertical is:

Emission of light from an atom occurs when an electron

Which is an example of transfroming potential energy to kinetic

Place the ball in the plastic bag, and twist the top so the ball is secure in the bag. Wrap the twisted portion with tape so it stays tight. Use the hole punch or scissors to poke a hole in the part of the bag that's above the ball.
