Answer
A. the work done on the refrigerant in each cycle is 105kJ
B the coefficient of performance of the refrigerator is 4.8
Explanation
Given data
Work done at high temperature T2 Qh=610kJ
Work done at low temperature T1 Ql=505kJ
We know that the net work done by the refrigerator is expressed as
Wnet= Qh-Ql
=610-505
=105kJ
Also we know that the coefficient of performance is expressed as
COP= Ql/Wnet
COP= 505/105
= 4.8
Answer:
the long wavelength and not focused on the negatives.
Answer:
t = 0.4 s
Explanation:
Given that,
The speed of sound on steel is about 5000 m/s.
A friend of yours, 2000 m away, strikes a railroad track which you have your ear on.
We need to find the time after she strikes it will the sound arrive. Let the time is t. We know that,
Speed = distance/time
So,
So, the required time is 0.4 seconds.
