Answer:it causes the moving object to slow eventually stop
Explanation:
Answer:
All magnets have two poles: the North Pole and the South Pole.
Magnets attract ferromagnetic materials such as iron, nickel, and cobalt.
The magnetic force of a magnet is stronger at its poles than in the middle.
A freely suspended magnet always points in North-South direction.

The average acceleration of the cheetah is 7.75 m/s²
The given parameters;
velocity of the cheetah, v = 31 m/s
time of motion, t = 4 seconds
The average acceleration of the cheetah is calculated as follows;

where;
v is the final velocity
u is the initial velocity
t is the time of motion
Assuming the cheetah started from rest, the initial velocity, u = 0
The average acceleration is calculated as follows;

Thus, the average acceleration of the cheetah is 7.75 m/s²

Due to Ohm's law, I is proportional to V and 1/R:
I ∝ V
I ∝ 1/R
R is proportional to the wire length L:
R ∝ L
Therefore I is also proportional to 1/L:
I ∝ 1/L
Calculate the scale factor due to increased voltage:
k₁ = 24/12 = 2
Calculate the scale factor due to decreased wire length:
k₂ = 1/(0.5/1) = 2
Multiply the original current by the scale factors to get the new current:
I = I₀k₁k₂
I₀ = 100mA, k₁ = 2, k₂ = 2
I = 100(2)(2)
I = 400mA
