Answer:
By nature, laws of Physics are stated facts which have been deduced and derived based on empirical observations. Simply put, the world around us works in a certain way, and physical laws are a way of classifying that “working.”
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.
Answer:
It take 1.78033 second get away
Explanation:
We have given that a car takes 30 m to stop when its speed is 25 m/sec
As the car stops its final speed v = 0 m/sec
Initial speed u = 25 m/sec
Distance s = 30 m
From third law of motion
So
Now in second case distance s = 28 m
So
v = 6.4549 m/sec
Now from first equation of motion v=u+at
So
t = 1.78033 sec
Answer:
80 A
Explanation:
Hi there!
Ohm's law states that where V is the voltage, I is the current and R is the resistance.
Plug the given information into Ohm's law (V=0.8, R=0.01) and solve for I
Divide both sides by 0.01 to isolate I
Therefore, the current for this circuit would be 80 A.
I hope this helps!
