How does convection affect our atmosphere? our layers of earth? our oceans?

Distinguish between a transverse wave and a longitudinal wave.

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.
