Answer:
61257.6 kW per day
Explanation:
The rating of the refrigerator is given as : 709 w
This means the power consumption is 709 joules per second
The operating time is given as 10 hours.
Change hours to second as
1 hour = 3600 seconds
10 hours = 36000 seconds
Apply the rating as;
709 w = 1 s
? = 36000 seconds
perform cross product to get;
709 * 36000= 25524000 w
25524000 = 25524kW
For a day, 24 hours will be;
25524 kW = 10 hours
? =24 hours
={24*25524}/10 = 61257.6 kW per day

Answer:
The change in internal energy of the engine is -1,571 Joules.
Explanation:
Change in internal energy (∆U) = energy output (U2) - energy generated (U1)
U1 is the energy generated = 2203 Joules
U2 is the energy output = 632 Joules
Change in internal energy (∆U) = 632 - 2203 = -1,571 Joules
