Answer:

A continuous transmission of energy from one location to the next.

Explanation:

Wave is a disturbance which continuously transmit energy from one location to another. It does not transmit any mass. There are many types of waves like mechanical wave, electromagnetic wave, gravitational waves etc.

The speed of a wave is given by :

$v=\nu \times \lambda$

$\nu$ is the frequency of wave

$\lambda$ is the wavelength of the wave

So, the correct option is (d) "a continuous transmission of energy from one location to the next".

Correct answer choice is:

D. A continuous transmission of energy from one location to the next.

Explanation:

Waves include the carrier of energy without the carrier of matter. In outcome, a wave can be characterized as a change that progresses into a medium, carrying energy from one spot (its source) to different spot without carrying matter.

A refrigerator removes 55.0 kcal of heat from the freezer and releases 73.5 kcal through the condenser on the back.How much work

sammy [17]

Here refrigerator removes 55 kcal heat from freezer

Refrigerator releases 73.5 kcal heat to surrounding

So here we can use energy conservation principle by II Law of thermodynamics

the law says that

$Q_1 = Q_2 + W$

here we know that

$Q_1$ = heat released to the surrounding

$Q_2$ = heat absorbed from freezer

W = work done by the compressor

now using above equation we can write

$73.5 = 55 + W$

$W = 73.5 - 55$

$W = 18.5 kcal$

So here compressor has to do 18.5 k cal work on it

Answer :First part is what you learned so write what you learned then the other parts is The evidence that the universe is expanding comes with something called the red shift of light. Light travels to Earth from other galaxies. As the light from that galaxy gets closer to Earth, the distance between Earth and the galaxy increases, which causes the wavelength of that light to get longer.
