<span>The unit for potential energy per unit charge, or voltage, is the volt, which has the symbol "V." It takes its name from the Italian physicist Alessandro Volta, credited with inventing one of the first electric batteries.Voltage refers to the work that would be necessary for each unit charge against the existing electric field to move a charge from Point A to Point B. One volt is the equivalent of multiplying one ampere (a unit of current) by one ohm (a unit of resistance). To get the power in terms of watts, it is necessary to multiply the voltage by the current in amps.</span>
Answer:
2pi
Step-by-step explanation:
Perimeter of square is 48 inches.
Square has 4 side so one side is 48/4= 12 inches.
Then the area of square is 12*12 = 144 inches^2
Answer:
8/27 ≈ 29.6%
Step-by-step explanation:
Two of the six faces are B, which means four of the six faces are not B.
The probability of rolling not B three times is:
P = (4/6)^3
P = (2/3)^3
P = 8/27
P ≈ 29.6%
