Lifting weights, did this yesterday :))
I believe the answer is b. external stimulus
As the balls continue to accelerate to the ground, the distance between them before the first ball hits the ground will increase.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Two identical heavy balls are dropped from the top of the Leaning Tower of Pisa. The second ball is dropped 1 s after the first ball. The first ball start falling 1s earlier than the second ball. Thus, the acceleration for first ball will be greater than the second ball.
Thus, the distance between them before the first ball hits the ground will increase.

Answer:
Explanation:
From the question we are told that:
Current 
Angle 
Magnetic field 
Length 
Generally the equation for Magnetic force F is mathematically given by
Therefore
If you start at 100% and divide it by 2 it will equal 50% then divide by 2 again and the answer will be 25%. Your answer should be 25%
