758 j of heat are added to 0.750 kg of copper. how much does its temperature change?(unit=degrees c) PLEASE HEL M

Explanation:

When a substance is supplied with a certain amount of heat energy, the temperature of the substance increases according to the equation

where

m is the mass of the substance

Q is the amount of energy supplied

C is the specific heat of the substance

is the temperature change

In this problem:

Q = 758 J is the energy supplied

m = 0.750 kg is the mass of the sample

is the specific heat of copper

Re-arranging the equation, we can find the increase in temperature:

im not to sure what it is

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
