Solve a and b using energy considerations.

a) a 0.80 kg coconut is growing 10 m above the ground in a palm tree. the tree is just at the edge of a cliff that is 15m tall. what would the maximum speed of the coconut be if it fell to the ground at the base of the tree?

b) what would the maximum speed be if it fell from the tree to the bottom of the cliff?

Explain why you think this diagram shows what happened to the carbon in the biodome.

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.
