<span>The larger the current flowing in a wire, the stronger the magnetic field
is that surrounds the wire.
That's why, if you want to make an electromagnet stronger, one way to
do it is to add another battery. By increasing the voltage, you'll increase
the current flowing in the coils of wire, and the electromagnet will be stronger.</span>
A. Layer C is the right answer out of all the choices
Answer:
<h2>3000 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 750 × 4 = 3000
We have the final answer as
<h3>3000 N</h3>
Hope this helps you
