Answer:Explanation: According to Newton's third law, the force exerted by the bat hitting the ball will be equal in magnitude but opposite in direction of the force the ball exerts on the bat. Generally, your arms are stiff when you hit the ball forward, so you will not feel the bat "recoiling".
Explanation:
Answer:
The current in the motor in this case is 13.2 A
Explanation:
Given:
Resistance
5 Ω
Emf
V
Induced emf
V
When motor run at half speed due to load increased then induced emf is also reduced to half of its value
So new induced emf in our case is given by,
V

Where


A
Therefore, the current in the motor in this case is 13.2 A
125 kmph
250=2
X=1
250/2= 125
because it deals with reaction
