715 J of heat are transferred from a 1.30 kg aluminum block to a
0.800 kg iron block. Find the
temperature change for the
aluminum
Aluminum
Iron or steel
c = 900 J/(kg*c)
c = 452 J/(kg"C)
(Unit = degrees C)

0.61

Explanation:

the answer is 0.61 because i just typed it into acellus abs it was right

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
