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

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
