Which is not true of the weak nuclear force? a. it is a repellent force. b. it acts over a shorter range than the strong nuclear force. c. it is an attractive force. d. it is weaker than the strong nuclear force.

Option (A) is the correct answer.

Explanation:

A force that helps in binding protons and neutrons together in a nucleus is known as nuclear force. It is known that neutrons have no charge whereas protons have positive charge and like charges repel each other but due to the strong nuclear force which over powers the repulsion force between protons, they are held together in a nucleus.

A weak nuclear force is weaker than the strong nuclear force. Also, it acts over a shorter range than the strong nuclear force. A weak nuclear force is also attractive in nature.

But a weak nuclear force is not repellent in nature.

Thus, we can conclude that a weak nuclear force is a repellent force is not true.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

this would be about 43%
