Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
9 to the 2 power is 81 9x9=81 When you are calculating powers you are really multiplying the first number by itself the number of times the second number says. so for 9 to the 2 power you are multiplying 9 by itself 2 times
7.5 watts
Approximately 0.01341 horsepower or 0.01 kilowatts.
The answer depends on the mass of the piano and the height of the floor.
Well, darling, the square root of x to the 8th power is x to the 4th power. It's like cutting a cake into 8 equal pieces and then taking the square root to get 4 pieces. Simple math, just like how I like my martinis – straight to the point.

The main piece of information needed is the load wattage or amperage that will be connected to the power supply. Once this is known the power supply of a greater size that the load should be chosen. Also with this information the size of the wires can be calculated from the power supply to the load. Too small a wire will create a voltage drop at the load end of the circuit. This will cause under performance of the load.
The formula for calculating power if you are given a magnetic field is sub 43
An autorefractor works by measuring how light is reflected off the retina to determine the eye's focusing ability. This information helps determine the person's eyeglass prescription by calculating the precise lens power needed to correct any vision issues.
The correct formula for calculating power is: Power = Work/Time.
The formula for calculating current in a circuit when given the values of power and resistance is i p/a.
The formula for calculating power in a circuit using the keyword "power i 2r" is P I2 R, where P represents power, I represents current, and R represents resistance.
volts X amps
Power is energy divided by time, P=E/t.
The formula for calculating power loss in a circuit is P i2 R, where P represents power loss, i is the current flowing through the circuit, and R is the resistance of the circuit.
The formula for calculating power loss in transmission lines is Ploss I2 R, where Ploss is the power loss, I is the current flowing through the transmission line, and R is the resistance of the transmission line.
