You throw a basketball by exerting a force of 20 newtons. According to Newton's third law, there is another 20 -newton force created in the opposite direction. If there are two equal forces in opposite directions how does the ball accelerate ?

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.

Ajoint produces movement when its angle decreases. which type of movement is it?

Use the illustration to describe how the electromagnetic spectrum changes as its frequency moves from radio waves to higher energy gamma waves in terms of wavelength and amplitude.
