If the fly experienced a force of 100 N when it hits how big was the force on the vehicle in this collision

iogann1982 [59]

Answer:

100N

Explanation:

because newton's third law of motion states that if body A exerts a force on the body B, then Body B will exert an equal force but opposite in direction force on body A

so if the fly experienced 100N, then the car will also experience 100N

hope you get it

These are intense, rotating convectional systems that develop over warm ocean areas in the tropics and subtropics, primarily dur

asambeis [7]

Answer:

True.

Explanation:

During the late summers the SST (sea surface temperature) rises the most which made the wind above the sea moist and warm. Global warming is also one of the cause of the rise in sea surface temperatures. Then the Coriolis effect due to the earth's rotation make these winds to rotate which results in the formation of the cyclones mostly in the areas near to equator.

a simple machine that combines two inclined planes and is used to split objects is called a . group of answer choices

Semmy [17]

Answer:

The answer is a wedge.

Explanation:

The wedge is a combination of two inclined planes. It is used to separate bodies which are held together by large forces, e.g, splitting timber

M.A.= slant height of wedge/thickness of wedge.

Hence a long thin wedge has a higher mechanical advantage than a short thick one; or the smaller the angle theta between the slant heights, the greater the mechanical advantage.
