A waterfall is 1260m high. calculate the change in temperature of the quantity of water that falls from the top to the bottom of the waterfall( neglect heat losses to the surrounding) take g to be 10m/s and specific.heat capacity of water to be 4200j/kg/k.

Answer 1

What????
Put down the pipe and walk away from the classroom...

Answer 2

i have not seen the answer

Answer 3

mgh = mc▲t
cancel 'm' on both sides
gh = c▲t
10*1260 = 4200*▲t
(10*12600) / 4200 = ▲t
3 K = ▲t
