A1.0 kg piece of copper with a specific heat of ccu=390j/(kg⋅k) is placed in 1.0 kg of water with a specific heat of cw=4190j/(kg⋅k). the copper and water are initially at different temperatures. after a sufficiently long time, the copper and water come to a final equilibrium temperature. part a which of the following statements is correct concerning the temperature changes of both substances? (ignore the signs of the temperature changes in your answer.) which of the following statements is correct concerning the temperature changes of both substances? (ignore the signs of the temperature changes in your answer.) the temperature change of the copper is equal to the temperature change of the water. the temperature change of the water is greater than the temperature change of the copper. the temperature change of the copper is greater than the temperature change of the water.

The temperature change of the copper is greater than the temperature change of the water.

Explanation:

deltaQ = mc(deltaT)

Where,

delta T = change in the temperature

m =mass

c = heat capacity

The temperature change in the copper is nearly 11 times the temperature change in the water.

So, the correct option is,

The temperature change of the copper is greater than the temperature change of the water.

Hope this helps!

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
