Answer:
When you exert a force on a baseball, there exists an equal and opposite force on the ball therefore, the ball will accelerate in opposite direction.
Explanation:
When you hit a ball with baseball bat, the bat exerts a great force on the ball which causes the ball to accelerate in the opposite direction. It is to be noted that the mass of bat is much greater than mass of ball but the acceleration of ball is also greater than the acceleration of the bat so both bat and ball almost exert same magnitude of force but in opposite direction and as a result both bat and ball accelerate in opposite direction, the deciding factor is of course the relative force applied by the batter and the bowler.
W = KE = 1/2m(v2f-v2i) also known as D just took the test
The answer is sunlight I just had this question and got it right. Please make brainliest
Answer:
Assume that 
. The net force on this object will be 
(downwards.) The acceleration of this object will be approximately 
(also downwards.)
Explanation:
<h3>Net force</h3>
The object is falling towards the ground because of gravity. The size of the gravitational force on this object depends on its mass and the strength of the gravitational field at its location.
Near the surface of the earth, the gravitational field strength is approximately 
. In other words, approximately 
of gravitational force acts on each kilogram of mass near the surface of the earth.
The mass of this object is given as 
. Therefore, the size of the gravitational force on it will be:
.
Near the surface of the earth, gravitational forces point towards the ground. On the other hand, the direction of air resistance on this object will be opposite to its direction of motion. Since this objects is moving towards the ground, the air resistance on it will be directed in the opposite direction. That's exactly the opposite of the direction of the gravitational force on this object. The net force on this object will be:
.
<h3>Acceleration</h3>
Let 
denote the acceleration on this object. Apply Newton's Second Law of motion:
.
Note that the acceleration of this object and the net force on it should be in the same direction.
The correct option is C.
In an electric circuit, resistance is defined as the friction in an electrical circuit which controls the flow of current. In an electric circuit, the resistance involved determined the amount of voltage that will be released; the higher the resistance the lower the voltage that will be released and the lower the resistance the higher the voltage that will be released. Thus, in a situation where the current released is too high, then the resistance has to be increased to lower the current.
