Answer:
72 km/h
Explanation:
Speed of car = 20m/s
So, here to find the speed in km/h we will change the metre to km and seconds to hours .
=>
= 72 km/hr
to change into km divide by 1000
(1 m = 1/1000km)
and,
to change into hours divide by 60*60= 3600

Answer: 11,000 J
Explanation:
In an isothermal process,
(1)
Note that, the energy used in heat transfer is not available for work. So, the amount of energy unavailable for work is equal to the energy used in heat transfer.
To obtain the amount of energy in heat transfer, we multiply both sides of equation (1) by the denominator of the right side of (1) so that
amount of energy in heat transfer = (entropy increase)(temperature)
= (25 J/K)(440 K)
= 11,000 J
Since the amount of energy unavailable for work is equal to the amount of energy in the heat transfer, therefore the amount of energy unavailable for work is 11,000 J.
