Superman is standing 393 m horizontally away from lois lane. a villain drops a rock from 4.00 m directly above lois. if superman is to intervene and catch the rock just before it hits lois, what should be his minimum constant acceleration? if the acceleration is toward lois, enter a positive value. if the acceleration is away from lois, enter a negative value.

-963.93 m/s²

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

The acceleration of Superman would be -963.93 m/s² from Lois' perspective

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 answer for apex is the lowest
