Answer:

Explanation:

The engine should create the same force

1) F = ma

  F = M(½a)

therefore

ma = ½Ma

 m = ½M

 M = 2m

 M = 2(0.8)

 M = 1.6 kg

2) Unbalanced forces

 a. Two people pulling on the same side of a wheelbarrow

 c. Two people of opposite sides of a big tire. One pushes the tire and one pulls it with equal force

3) b. The force of friction on the object is different if it is stationary or not

<span>The acceleration of the bullet is called ACTION.

</span>Formally stated, Newton's third law<span> is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Newton’s third law in football?
trapecia [35]
Newtons third law of motion applies to football as when the ball is thrown, force is applied to the football thrown forward and also force back to the player. Therefore it states that every action has a reaction. The player does not get a huge force back from throwing the football due to the player having a bigger mass than the football being thrown.

In short, when the football is throw, there is a reaction with the ball and the player accordingly with the force put into the ball.

HURRY WILL MARK BRAINLIEST Farha makes the graphic organizer shown to review the characteristics of transistors.
BabaBlast [244]

Answer:

<em>C. It is made from three layers of semiconductors.</em>

<em></em>

Explanation:

<em>Bipolar transistors (pnp and npn) are usually made from a sandwich of three semiconductors layers</em>. The main charge carriers are holes and electrons. An npn transistor has two semiconductor junctions that share a thin middle positively enhanced region (the material is enhanced with impurities rich in holes which are the positive charge carriers), and a pnp transistor has two semiconductor junctions that share a thin middle negatively enhanced region (material is enhanced with impurities rich in electrons, the negative charge carriers).
