Answer:
The correct option is D
Explanation:
From the question we are told that
The maximum electric field strength is
The area is
Generally the force the laser applies is mathematically represented as
Here
=>
As the ball rises, its velocity decreases at a rate equal to 9.8 m/s^2 which is the gravitational acceleration.
At the highest point, the velocity of the ball is 0. It then starts to fall down and reaches the ground in the same duration of time it took to rise to the highest point. The velocity of the ball is equal in magnitude to the velocity it was thrown up but opposite in direction.
This gives the velocity of the ball when it returns to the starting point as -7.7 m/s
The time taken by the ball is 2*(7.7/9.8) = 1.57 seconds
Answer:
hi how are u fine thanks you
Answer:
450
Explanation:
total magnification = eyepiece lens x objective lens
10 x 45 = 450
Explanation:
i hope this helps, its not the same person but its the same equation.
