A 10-20 vdc power source is a low output power supply used for small devices like battery chargers, notebook computers, and appliances. They use AC power input to convert it into DC power.
1. If you do work on an object in one-third the usual time, your power output is A) one third the usual power output. B) the usual power output. C) three times the usual power output. D) impossible to predict without additional information. Answer: C
it would be 9 times yesterday's power output
for example 2 to the power of two thirds, you have to find the percent of two thirds , then use the percent [to the power] then mutipy to the power [like with exponets] then you should get your answer.
The power could then be called an exponent. The number that is being raised to a power is called the base. In the case of 42, the exponent is 2 and the base is 4.
