Answer: Newton's third law of motion states that for every action, there is an equal and opposite reaction. When a player hits a ball with a bat, the force the player exerted on the ball through the bat gave the ball a push force in the forward direction.
Explanation:
B. motion, because if a body isn’t moving and you apply a moving force to it it will then cause the body to be put into motion as well
The time taken is approximately 26 minutes
Explanation:
The motion of the body in this problem is a uniform motion (= at constant velocity), therefore we can use the following equation:
where
v is the speed
d is the distance covered
t is the time taken
In this problem, we have
v = 75 km/h is the speed
d = 32 km is the distance to be covered
Solving for t, we find the time needed:
Converting into minutes,

Answer:
A. 1/50π V
Explanation:
Given;
magnetic flux through the coil, φm = (1/50π) cos 100πt
t = 1/200 s
The magnitude of the induced EMF is given by;
Therefore, the magnitude of the induced EMF is 1/50π V
The correct option is "A. 1/50π V"
