Answer:

Option C, It was a time of solar maximum, and there had been a big flare on the Sun earlier

Explanation:

It was solar maximum due to which the amount of magnetic flux on the sun's surface rises up

This causes high frequency radio blackouts and interrupt with the communication on earth

Some times they also cause ripple effect in the electronic items as in the remote control used by the college student. They can disrupt the electronic communications.

Hence, option C is correct

Triss [41]

Answer:

22.5 m

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 30 m/s

Time (t) = 1.5 s

Final velocity (v) = 0 m/s

Distance (s) =?

The distance to which the car move before stopping from the time the driver applied the brake can be obtained as follow:

s = (u + v)t/2

s = (30 + 0)1.5 / 2

s = (30 × 1.5) / 2

s = 45 / 2

s = 22.5 m

Thus, the car will move to a distance of 22.5 m before stopping from the time the driver applied the brake.
