The 1.5kg cylinder C travels along the path described by r sin m  0.6   . If arm OA is rotating counterclockwise with an angular velocity of   3 / rad s, determine the force exerted by the smooth slot in arm OA on the cylinder at the instant 60o   . The spring has a stiffness of 100 / N m and is unstretched when 30o   . The cylinder is in contact with only one edge of the slotted arm. Neglect the size of the cylinder. Motion occurs in the vertical plane (which means to account for gravity)

d is the answer i came up with

i believe it is b. what was the cause of the big bang

hope this !

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.
