Answer: The total rate of heat transfer from the container to its surroundings ignoring radiation is 332.67 W.
Explanation:
Given: Inner diameter = 0.9 m
q = 872
Now, radii is calculated as follows.
Hence, the rate of heat transfer is as follows.
where,
V = volume of sphere =
Substitute the values into above formula as follows.
Thus, we can conclude that the total rate of heat transfer from the container to its surroundings ignoring radiation is 332.67 W.
Answer:
The kinetic energy of the car at the top of the hill is 140280 Joules.
Explanation:
Mass of the car, m = 620 kg
Speed of the car, v = 24 m/s
Height of the hill, h = 30 m
The engine can produce up to 144,000 J of work during that time, W = 144,000 J
We need to find the kinetic energy of the car at the top of the hill. It can be calculated using conservation of mechanical energy as :
So, the kinetic energy of the car at the top of the hill is 140280 Joules. Hence, this is the required solution.
