Answer:
- 1100 J heat flows out
Explanation:
dW = - 1600 J (as work is done on the gas)
dU = 500 J
dQ = ?
According to the first law of thermodynamics
dQ = dU + dW
dQ = 500 - 1600
dQ = - 1100 J
As heat is negative so it flows out.
Explanation:
electrical potential = (6.6-3.4)/0.20
= 16 uc/m
It would be a high pitched sound. Hope this helps.
Definitely D. The brakes on a bike rub against the wheel. Not sure about the others.
