Two shuffleboard disks of equal mass, one orange and the other yellow, are involved in an elastic, glancing collision. the yellow disk is initially at rest and is struck by the orange disk moving with a speed of 5.80 m/s. after the collision, the orange disk moves along a direction that makes an angle of 39.0° with its initial direction of motion. the velocities of the two disks are perpendicular after the collision. determine the final speed of each disk.

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.
