It is know as the normal force.


When a solid is placed on a support, the latter exerts forces on the solid at each point of contact. These are forces that oppose the weight and prevent an object from falling.

This force is usually vertical and upward and often offsets the weight. If the solid is in equilibrium on the support the forces compensate the weight of the solid.

The correct order given below shows the changes that occurs in a mice population in response to changes in their environment:

  • The population of mice is in an environment with many black rocks
  • Mice with black for are more likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have black fur
  • A sandstorm covers most of the population's environment with brown sand
  • Mice with black fur are less likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have brown fur

<h3>What is the correct order for natural selection in the desert environment given?</h3>

Based on the process of natural selection due to envrionmental pressures, the population of the mice in the desert changes as follows before and after the environmental change:

  • The population of mice is in an environment with many black rocks
  • Mice with black for are more likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have black fur
  • A sandstorm covers most of the population's environment with brown sand
  • Mice with black fur are less likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have brown fur

Therefore, the correct order shows the changes that occurs in a mice population in response to changes in their environment.

8. Bring the balloon in contact with the wall. What happens to the charges in the wall?
Ne4ueva [31]

When the charged balloon is brought near the wall, it repels some of the negatively charged electrons in that part of the wall. Therefore, that part of the wall is left repelled.

<u>Explanation</u>:  

  • Balloons don't stick to walls. However, if you rub the balloon on an appropriate piece of material such as clothing or a wall, electrons are pulled from the other material to the balloon.
  • The balloon now as more electrons than normal and therefore has an overall negative charge. Two balloons like this will repel each other.
  • The other material now has an overall positive charge. Because opposite charges attract, the balloon will now appear to stick to the other material. If you didn't rub the balloon first, it's charge would be neutral and it wouldn't stick to the wall.
