Explain! i don’t understand how to find the answer.

a metal bolt with a mass of 8.50 x 10^-2kg and a temperature of 85.0°c is placed in a container of water. the mass of the water is 0.150 kg, and its temperature is 25.0°c. what is the specific heat capacity of the bolt if the final temperature of the bolt and water is 28.4°c? (specific heat of water= 4186 j/kg·°c)

50 inches should be the resultant vector

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
