Answer: Option (d) is correct.
Explanation:
Given, 1,152 British thermal units
1 British thermal unit = 1055.06 joules
So, in 1,152 British thermal units there will be :
Hence, from the given options the closest answer is of option (d). So, option (d) is correct.
Answer:the mass Of The object,and there area Of The bottom surface
Explanation:
There mass Of The object, and the area Of The bottom surface
Ok, a couple of things have to be accounted for here. First, since the block is moving relative to the wall we have to use the
kinetic coefficient of friction, 0.40. The second consideration is that since the block is moving at a constant velocity, the acceleration is
zero. This means, by Newton's second Law, that the net force is zero. So the force of gravity must be equal to the friction force of the wall resisting its fall. This friction force is the product of the normal force (which we are seeking) and the kinetic coefficient of friction. We can then set these two forces equal:
Answer: Final Temperature= 40.57 deg C; Latent Heat of Fusion of Ice= 80.14 cal/g
Explanation:
The system is said to be isolated to the surroundings. All energy must remain inside the system. We can state that no loss of energy takes place, thus,
