What explosion in the upper solar atmosphere releases about as much energy as millions of 100-megaton hydrogen bombs exploding simultaneously?

Solar flare

Explanation:

In the Sun when there is an sudden increase in brightness which is generally accompanied by a coronal mass ejection it is known as a solar flare. Solar flares occur close to Sun spot.

Coronal mass ejection is the release of matter (plasma) with a strong magnetic field from the corona of the Sun.

The energy they release ranges between which is comparable to 100-megaton hydrogen bombs exploding simultaneously

it is true because as we rotate around the way we rotate makes day come and because the moon is rotating around the earth that's what makes it night come. hope this .

the total distance traveled by the car is

30km + 49km = 79 km .
