The water flowing over niagara falls drops a distance of 50 m. if all the gravitational potential energy is converted to thermal energy, by what temperature does the water rise? the specific heat of water is 4186 j/kg ∙ k. a)0.42 c° b)0.37 c° c)0.12 c° d)0.10 c°

Answer :  (C)  0.12 C°

Explanation :

It is given that all the gravitational potential energy is converted to thermal energy.

So, the thermal energy is balanced by gravitational potential energy.

Gravitational potential energy,

And amount of heat is,

Where, c is specific heat.

So,

or

Hence, this is the required solution.

Correct option is (C)  0.12 C°.

answer: its c lololo
