Which two fundamental forces act within an atom's nucleus?

3 & 4 the strong nuclear force the weak nuclear force

Which force has an infinite range and is always attractive?

A. the gravitational force

The electromagnetic force is

C. both attractive and repulsive.

When water flows from a faucet, the water molecules tend to join together and form a stream. Which of the four fundamental forces most likely accounts for this?

C. the electromagnetic force

Which force prevents protons from repelling each other inside a nucleus?

D. the strong nuclear force

If the gravitational force exists between all objects in the universe, why aren't people affected by the gravitational force exerted by cars and buildings?

People are not affected by the gravitational force of cars and buildings because their masses are too small to exert a strong enough force for people to feel. The weak gravitational forces of cars and buildings are insignificant compared to the gravitational force of Earth.

Rank the four fundamental forces from strongest to weakest. Use 1 to indicate the strongest force and 4 to indicate the weakest force.

The gravitational force: 4 The electromagnetic force: 2 The strong nuclear force: 1 The weak nuclear force: 3
