It’s a sunny Saturday afternoon and you are walking around the lake by your house, enjoying the last few days of summer. The sidewalk surrounding the perimeter of the circular lake is crowded with
walkers and runners. You then notice a runner approaching you wearing a T-shirt with writing on it.
You read the first two lines, but are unable to read the third line before he passes. You wonder,
”Hmmm, if he continues around the lake, I bet I’ll see him again but I should anticipate the time when
we’ll pass again.” You look at your watch and it is 5:07pm. You estimate your walking speed at 3 m/s
and the runner’s speed to be about 14 m/s. You also estimate that the diameter of the lake is about 2
miles. At what time should you expect to read the last line of the t-shirt?

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.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

god i hope this !
