The table shows results from an experiment in which objects made up of different materials are rubbed with each other. Based on

the results, what can be predicted if an object made of rubber is rubbed with an object made of glass? A) The glass object will become negatively charged, and the rubber object will remain neutral. B) The rubber object will become negatively charged, and the glass object will remain neutral. C) The glass object will become negatively charged, and the rubber object will become positively charged. D) The rubber object will become negatively charged, and the glass object will become positively charged.

Answer:

D) The rubber object will become negatively charged, and the glass object will become positively charged.

Explanation:

Electron affinity of rubber or glass will decide the thing that rubber will get the negative charge or the glass will get the negative charge

As we know that if the electron affinity of a given material is high then that material will not lose its electron while rubbing with some other material.

When we compare rubber and glass then we know that electron affinity of rubber is more as compare to glass.

So rubber will get negative charge when we rub it with glass

so correct answer will be

D) The rubber object will become negatively charged, and the glass object will become positively charged.

Which of these statements best proves that electromagnetic forces are weaker than strong nuclear forces? Neutrons do not repel o
musickatia [10]
Answer: <span>Protons do not move out of the nucleus of atoms although they repel each other.

Reasoning:

Remember that protons are particles with positive charge and they held together in the nucleus of the atom which is a tiny tiny region. As you know, like charges repel each other, which means that the protons exert a repulsion force.

That repulsion force tends to destabilize the atom. The only reason why the atom does not explode is because there is a there exists a force of attraction that exceeds the repulsion of the like charged protons. That is the strong nuclear force. Therefore, the strong nuclear forces are stronger than the electromagnetic force that tends to get the protons apart.

A person walks in the following pattern: 3.1 km north, then 2.4 km west, and finally 5.2 km south. a) Sketch the vector diagram
zysi [14]

Answer:

d = 3.19 km

direction is given as

\theta = 41.2 degree South of West

Explanation:

Part b)

displacement is given as

d_1 = 3.1 \hat j

d_2 = 2.4 \hat i

d_3 = 5.2(-\hat j)

now we will have

d = d_1 + d_2 + d_3

d = 2.4 \hat i + (3.1 - 5.2)\hat j

d = 2.4 \hat i - 2.1 \hat j

total displacement is given as

d = \sqrt{2.4^2 + 2.1^2}

d = 3.19 km

direction is given as

tan\theta = \frac{-2.1}{2.4}

\theta = 41.2 degree South of West
