Una pelota de 30 CM de diámetro s sumerge totalmente en una alberca, si la pelota tiene una masa de 380 g el Pe de agua es de 9800 N/m3 calcular: a) ¿Que magnitud de empuje recibe?
b) ¿Cuál será la magnitud del peso aparente de la pelota?

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.

Give an example of how both short term and long term memory are involved. explain procedural, semantic ,and episodic memory and then how each is involved in this
