Answer:
0 J
Explanation:
If it's at the same temperature then it doesn't need more heat. So it'd be 0 J since it's already at 0C.
Answer:
(a) Angular speed will be 0.2512 rad/sec
(b) Radius will be 213.375 m
Explanation:
We have given time to complete 1 lap = 25 sec
We know that 1 lap =
radian
(a) So angular speed 
(B) Tangential velocity is given as v = 53.6 m/sec
We know that tangential velocity is given by

So radius

Characteristic properties of a given substance is different from its other properties is that there is no change as to what it is no matter how big or how small the sample of the given substance is. Another thing is that it doesn't affect the chemical nature of the matter. The characteristic properties of a given substance can either be a physical property of the substance or a chemical property of the substance. Either way, there is no change to it even if the size of the substance changes.
