Answer:
- The thermal efficiency is 0.4113.
Explanation:
We know that the thermal efficiency is the ratio of work done by the engine over the heat taken
Now, how much work the engine do in a cycle?
We know that the work done in a cycle must be equal to the heat taken minus the heat rejected
So, the thermal efficiency will be:
Putting the values of the problem
Answer:

Explanation:

Answer:
Explanation:
If the passage of the waves is one crest every 2.5 seconds, then that is the frequency of the wave, f.
The distance between the 2 crests (or troughs) is the wavelength, λ.
We want the velocity of this wave. The equation that relates these 3 things is
and filling in:
so
v = 2.5(2.0) and
v = 5.0 m/s
C.even though there is almost no material in the interstellar medium, but do transfer energy.
Explanation:
Light waves travels through space even though there is almost no material in the interstellar medium but do transfer energy.
A wave is any disturbance that transmits energy from one place to another.
- Light is a form of wave which belongs to the electromagnetic spectrum.
- They are propagated transverse to their source of energy.
- These electromagnetic waves are special types of waves.
- They are distinct because they do not require a material medium for their propagation unlike other waves.
- In the interstellar medium. a vacuum is in place.
- There are no matter that can be used for propagating waves.
- Light waves still passes through because they do not require any medium to propagate.
