Answer:
option C
Explanation:
When the baseball is hit high and far it has some horizontal velocity at the highest point so option an i.e. velocity at the highest point is eliminated.
the baseball act as a projectile at the highest point so, there is always downward acceleration acting on the body. so, option e and d is eliminated.
At the highest point, the vertical velocity is zero and neglecting the air resistance we can say that the velocity of the body is slowest.
Hence, the correct answer is option C
Answer: The answer is A.
Explanation:
Suppose you are in an elevator. As the elevator starts upward, its speed will increase. During this time when the elevator is moving upward with increasing speed, your weight will be greater than your normal weight at rest.
Answer:
Explanation:
If one assume that each turn is like a strand of electromagnet, which can then be added up. Therefore, increase in the number of turns will yield to increase in the magnetic strength. Also if the current increases, then there will be increase in the magnetic field strength.
From Ohm's law
V = IR
I = V/R
That is a direct increase in voltage will lead to increase in current.
Increase the voltage of the battery and increases the number of turns of the coil. Will suit the situation
It’s d because it’s useful output which would be light over total input
