What is the difference between transverse waves and longitudinal waves?

a. both move perpendicularly to the direction of energy movement

b. transverse waves move parallel and longitudinal waves move perpendicular to the direction of energy movement

c. both move parallel to the direction of energy movement

d. transverse waves move perpendicular and longitudinal waves move parallel to the direction of energy movement

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.

Arope has one end tied to a vertical support. you hold the other end so that the rope is horizontal. if you move the end of the rope back and forth with a frequency of 4 hz, the transverse wave you produce has a wavelength of 0.5 m. what is the speed of the wave in the rope?

Are good conductors of heat also good conductors of electricity? explain your answer.
