Answer:
Explanation:
P = mgh/t = 20(9.8)(4) / 5 = 156.8 W(atts)
Answer:
In-car temperature is controlled in a variable displacement compressor system by varying the capacity of the <em>refrigeration</em> not by cycling the <em>compressor </em>on and off.
Explanation:
A Variable Displacement Compressor (VDC) works in a separate and rather more efficient manner than the fixed displacement compressor (FDC). <em>The VDC automatically regulates the cooling effect of the refrigerator by changing its pumping capacity by means of a "wobbling piston" system. </em>
<em></em>
During times of peak load, the refrigeration pumping capacity is increased, delivering a large flow rate of refrigerant, thus giving a high refrigerating effect. The reverse happens during times of load refrigeration load.
<em>The fixed compressor tries to vary the temperature of the car by simply switching off the compressor</em>, and turning it on during times of low and peak loads.
Explanation:
We use Hooke's Law, which states that,
F=kx
F- is the force in newtons
k- is the spring constant
x- is the extension of the spring in meters
Solving for k we get k=F/x
k= 10N/0.50m
=100 N/m
Rare, noble or inert gasses have complete outer shells.
