What does the term "heat capacity" refer to? Question 2 options: The amount of heat energy needed to raise the temperature of a

unit mass of a material one degree A ratio of the amount of heat a material will absorb to the amount of heat it immediately releases The amount of heat that must be applied to a solid to convert it to a liquid The amount of heat that a liquid can absorb until the particles speed up enough to become a gas

Answer:

Heat capacity is the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature. Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K.

A car is strapped to a rocket (combined mass = 661 kg), and its kinetic energy is 66,120 J.
labwork [276]

Answer:

9.4 m/s

Explanation:

According to the work-energy theorem, the work done by external forces on a system is equal to the change in kinetic energy of the system.

Therefore we can write:

W=K_f -K_i

where in this case:

W = -36,733 J is the work done by the parachute (negative because it is opposite to the motion)

K_i = 66,120 J is the initial kinetic energy of the car

K_f is the final kinetic energy

Solving,

K_f = K_i + W=66,120+(-36,733)=29387 J

The final kinetic energy of the car can be written as

K_f = \frac{1}{2}mv^2

where

m = 661 kg is its mass

v is its final speed

Solving for v,

v=\sqrt{\frac{2K_f}{m}}=\sqrt{\frac{2(29,387)}{661}}=9.4 m/s

Which surface winds blow between the subtropical high and the equator
sasho [114]

Answer:

trade winds

Explanation:

In tropics regions on the lower portion of earth's atmosphere the surface winds are observed in prevailing pattern. In northern hemisphere the trade wind predominantly blows from north east. In southern hemisphere it flows from south east. Subtropical high and the equator is in between these areas.

Thus, trade wind blow between the subtropical high and the equator.

For the chemical reaction C2H6 --&gt; C2H4 + H2 + 137kJ, the chemical energy of the A. reactant and the chemical energy of the p
Goryan [66]

Answer: The chemical energy of reactants is greater than the chemical energy of products.

Explanation: In the given reaction

C_2H_6\rightarrow C_2H_4 + H_2 +137 kJ

It can be seen that the energy has been released. Thus we can say that reactants have converted to products by release of energy. Thus energy of products is less as compared to energy of reactants as some of the energy has been released.
