Which change increases the electric force between objects? A) Two neutral objects are moved closer together.
B) Electrons are added to two negatively charged objects.
C) Two oppositely charged objects are moved farther apart.
D) The charge on two positively charged objects is reduced.

Answers

By definition we have that the electric force is given by:

Where,

k: proportionality constant

q1: electric charge of object 1

q2: electric charge of object 2

d: distance between both objects

Therefore, to increase the electric power there are two possible cases:

1) Add more load to each object

2) Decrease the distance between objects.

The option that increases the electric force for this case is:

Electrons are added to two negatively charged objects.

This is because the values of q1 and q2 increase.

Answer:

A change that increases the electric force between objects is:

B) Electrons are added to two negatively charged objects.

Answer

B) Electrons are added to two negatively charged objects.

Jose has a solid green ball. Which color(s) of light does this ball reflect? A.
blue and yellow

B.
green

C.
all colors except green

D.
white

Answers

If the ball is green, then it is absorbing all the colors of light except green. This means that it is reflecting or denying the absorption of green light, that is why the ball is green. Therefore, your answer would be B.

Hope I helped :)

About 85% sure on this one.

The ball reflects the green because the ball absorbs all the other colors except green so that's why its the green light is covering it and its absorbing everything else

The atmosphere has many roles, including:

Answers

There are five layers of the atmosphere and these are; troposphere, stratosphere, mesosphere, thermosphere and exosphere. The first layer, troposphere, is where we are able to do most of our activities. This is where we can see the formation of clouds, the production of rain, hail, snow and other weather phenomenon. Also, this layer is where the greatest amount of air pressure because most of the molecules of air are in this area. Like us, air has also mass and the pressure is brought down by the earth’s gravity causing an increase in weight exerted on you as you descend lower into the atmosphere. So, as you enter into the other layers of atmosphere above the troposphere, the air pressure starts to decrease. Below the atmosphere is the hydrosphere. This is where all liquid forms are located. And since the seawater has a greater mass than air, it has the greatest pressure.

What is the total number of orbitals containing only one electron in an atom of nitrogen in the ground state?1
2
3
4

Answers

Answer: 3

Explanation:

Nitrogen is in subshell p which can only hold 6 electrons, therefore, it has three orbitals. Since Nitrogen has three electrons in this subshell, only one electron is in each orbital.

c is the answer. nitrogen is in subshell p and this subshell can hold 6 electrons therefore it has 3 orbitals. since nitrogen has three electrons in this subshell, only 1 electron is in each shell. hope that helps.

Given the diamond shape of a baseball field in the speed of which baseballs or hit why is it harder for a hitter to hit a homerun to the center field then to the right or left field

Answers

Because, say the diamond was 125 feet on both right and left fields, the center field would be 130 feet long, see what i mean? I hope I helped. :)
