B- we would need the time to fulfill the formula distance = speed x time
Electromagnet is in form of solenoid
and the magnetic field due to solenoid is given as

here
i = current in the loop
so when we increase the current in electromagnet the magnetic field of the solenoid will increase
this will increase the strength of the electromagnet
so the answer would be
<em>INCREASE</em>
A.Momentum Equation
m = mass = 75 kg
v = velocity = 18 m/s
P = momentum
Using the momentum equation , momentum is given as
P = mv
P = 75 x 18
P = 1350 kgm/s
Either A or D. If I were answering I'd go with my git answer and say A
Answer:
<h2>3.0 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

From the question we have

We have the final answer as
<h3>3.0 m/s²</h3>
Hope this helps you
