Asmall cylinder rests on a circular turntable that is rotating clockwise at a constant speed. the cylinder is at a distance of r = 12 cm from the center of the turntable. the coefficient of static friction between the bottom of the cylinder and the surface of the turntable is 0.45. what is the maximum speed vmax that the cylinder can have without slipping off the turntable?

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
