Adisplacement b of 100m from the origi at an angle of 37° above the x-axis is the result of three successive displacement b1 of 100 along the negative x-axis and a displacement b3 find b3

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.

come closer and become far apart and become steam/gas

force tends to be low and long diustance masses are high

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
