Answer: P = 0.416 kW
Explanation:
taken a step by step process to solving this problem.
we have that from the question;
the amount of heat rejected Qn = 4800 kJ/h
the cooling effect is Ql = 3300 kJ/h
Applying the first law of thermodynamics for this system gives us
Шnet = Qn -Ql
Шnet = 4800 - 3300 = 1500 kJ/h
Next we would calculate the coefficient of performance of the refrigerator;
COPr = Desired Effect / work output = Ql / Шnet = 3300/1500 = 2.2
COPr = 2.2
The Power as required gives;
P = Qn - Ql = 4800 - 3300 = 1500 kJ/h = 0.416
P = 0.416 kW

Answer:
Shearing strain will be 0.1039 radian
Explanation:
We have given change in length 
Length of the pad L = 1.15 inch
We have to find the shearing strain
Shearing strain is given by

Shearing strain is always in radian so we have to change angle in radian
So 
Answer:
yes, the recordings sound is same
Explanation:
given data
recording done = 2 performances
1st show = sold out
2nd show = lightly attended
to find out
recordings sound the same and why
solution
as per given in
- 1st show is sold out it mean in this case concert hall is full so that recording sound should be high here
- 2nd case only few people are attended and struggle for ticket and orchestra
it mean it sound performance so in both case recording sound will be same
because we do not other all are sitting at front row or they sit as they want
