We have heat lost by water is equal to heat gained by Juice.

Heat exchanged is calculated using the formula,

\Delta H=ms \Delta T

Let T_f be the final temperature then,

(1)(3)(T_f-10)=(1)(4.187)(15-T_f)\\  3T_f-30=62.805-4.187T_f\\  7.187T_f=92.805\\  T_f=12.913 K

The final temperature of the juice is 12.913 K.

This is a very valid hypothesis for many reasons. One is that solar systems form from massive amounts of dust, ice, and debris that eventually form into planets and such. This means it is very possible for this 'excess material' if you will to have moved into orbit behind Neptune.

How can we produce energy by turning a turbine?​
maw [93]
Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
