An electric circuit has an expected current of 80 amps. An electrician measures the current in the circuit at 120 amps Which statement provides a possible explanation for this observation? There is not enough electrical energy in the circuit.

The circuit has an extra resistor

There is not enough voltage in the circuit.

A resistor in the circuit is broken

An uplifted block of rock between two normal faults

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

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.
