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.

Answer:
249.5 minutes
Explanation:
Ali's speed is given by:

where
d is the distance covered
t is the time taken
We know that he can run d = 12 mi in t = 114 min, so he can keep a speed of

The length of a maraton is
L = 26.2 miles
So we can find the time it takes for Ali to complete the marathon as follows

Because the scientific method can go around in a circle as many times as neccisary to get the results you need
