A0.440-kg object attached to a spring with a force constant of 8.00 n/m vibrates in simple harmonic motion with an amplitude of 12.6 cm. (assume the position of the object is at the origin at t = 0.) (a) calculate the maximum value of its speed. cm/s (b) calculate the maximum value of its acceleration. cm/s2 (c) calculate the value of its speed when the object is 8.60 cm from the equilibrium position. cm/s (d) calculate the value of its acceleration when the object is 8.60 cm from the equilibrium position. cm/s2 (e) calculate the tim

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.

double the distance = divide strength by 4
