Please Please help, It's a physics question

0.5000 kg of water at 35.00 degrees Celsius is cooled, with the removal of 6.300 E4 J of heat. What is the final temperature of the water? Specific heat capacity of water is 4186 J/(kg C°).

Remember to identity all of your data, write the equation, and show your work.

The rocks expand when there hot/warm  and contract when they are cold.

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

What are your choices. i believe it might be mitochondria but i will know for sure when i see the choices. let me know okay i'm happy to answer

Despite their crazy structure, human bones are surprisingly good!
