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>
They stay with the microscope as it moves around to different schools, and they are always located in the same classroom where the rest of the microscope is being used.
Each parent contribute 50 percent. A person have 46 genes and 23 comes from the mother and 23 comes from the father
We can solve the problem by using Ohm's law, which states that an Ohmic conductor the following relationship holds:

where

is the potential difference applied to the resistor
I is the current flowing through it
R is the resistance
In our problem, I=4.00 A and

, so the potential difference is
Exothermich cools and endo heats so it heats
