So, there should be two forces acting on the refrigerator: the applied force and the friction force.
The question mentioned that the friction force was set to zero, so the only effective force now would be the applied force.
We have an applied force of 400 N to the right, this means that:
<span>The magnitude of the net force is 400, directed to the right.</span>
U=RI Ohm's law
then R=U/I
=120/0.08
=2250Ω
hope this helps you
I'd say the answer to this on is d.Facts as they are using the temperatures in the graph and the temperatures are not just estimates
<span>Like charges repel and opposite charges attract.
The further away two charged objects are the weaker the electrical force between them.
The closer two charged objects are the stronger the electrical force between them.
Hope this helps :)</span>
