You sit on your little brother's tiny chair. As soon as you sit on the chair it breaks. The force that is exerted by you (downwards) on the chair is 100 Newtons. Use what you learned about balanced and unbalanced forces to explain why the chair broke when you sat on it.

The explanation is below.

Explanation:

Forces that are equal in size but opposite in direction are called balanced forces. Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. ... Forces that cause a change in the motion of an object are unbalanced forces.

Unbalanced forces change the motion of an object. This happens in two ways. If an object is at rest and an unbalanced force pushes or pulls the object, it will move.

There was unbalance of force as my weight (100N ) was greater than the strength of the chair.

The tension created by my weight unbalanced the forced and it caused a negative reaction.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
