When we see a meteor shower, it means that

a. earth is crossing the orbit of a comet the solar wind is unusually strong meteor dust
b. is causing rain drops to condense in our atmosphere
c. an earth-approaching asteroid
d. has recently come very close to our planet

option A

Explanation:

The meteor shower is the celestial activity in which meteors are observed to radiate or originate from one point.

Meteors are nothing but dust or ice from the trails of comets. Most of the meteors are less than the size of the sand particle.

We will see comet shower when we earth will cross the orbit of the comet.

Hence, the correct answer is option A

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
