<span>This problem is relatively simple, in order to solve this problem the only formula you need to know is the formula for friction, which is:
Ff = UsN
where Us is the coefficient of static friction and N is the normal force.
In order to get the crate moving you must first apply enough force to overcome the static friction:
Fapplied = Ff
Since Fapplied = 43 Newtons:
Fapplied = Ff = 43 = UsN
and it was given that Us = 0.11, so all you have to do is isolate N by dividing both sides by 0.11
43/0.11 = N = 390.9 which is approximately 391 or C. 3.9x10^2</span>

Answer:
Explanation:
An adiabatic compressor is modelled as follows by using the First Law of Thermodynamics:
The power consumed by the compressor can be calculated by the following expression:
Let consider that air behaves ideally. The density of air at inlet is:
The mass flow through compressor is:
The work input is:
Radiation: transferred energy
Convection: Transfer of heat
Conduction: transfer of electric charge
