Given that an electric field of 3×106V/m3×106V/m is required to produce an electrical spark within a volume of air, estimate the length of a thundercloud lightning bolt.

Length, l = 33.4 m

Explanation:

Given that,

Electrical field,

Let the electrical potential is,

We need to find the length of a thundercloud lightning bolt. The relation between electric field and the electric potential is given by :

So, the length of a thundercloud lightning bolt is 33.4 meters. Hence, this is the required solution.

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
