Answer:
5kgm
Explanation:
convert cm to m and g to kg
250/1000=0.25kg
5/1000=0.05m
then find the density
density=mass/volume
=0.25kg/0.05m
=5kgm
Answer:
A)Qa=80 J
B)Qr= 100 J
Explanation:
Given that
W= 20 J
COP = 4
Heat rejected from cold reservoir = Qa
Heat exhausted to hot reservoir = Qr
The COP of refrigerator is given as
Qa= 4 x 20 J
Qa=80 J
By using first law of refrigerator
Qr= Qa + W
Qr= 80 + 20 J
Qr= 100 J
A)Qa=80 J
B)Qr= 100 J
