5p2 = 315 Therefore, p2 = 315/5 p = sqrt(63) p = ±7.94
p=pee
The Answer Is 120 :P -Kris
90-81=9 9/90=p(90)/90 9/90 0.1=p 10%
Go to school :P
if p² = 169, then p = ±√169 In other words, take the square root of 169 and p is either the positive or negative value of the square root.
The SI units for mechanical and electrical Power are the Watt (W), and the Watt (electrical) (We) respectively. Power is the rate of doing work, or that energy is converted. It can be thought of as - "amount of energy used to perform work, or converted from one form to another, in a specified period of time, namely, in a second".The equation is P=W/t, where P is Power, W is the work done and t is the time taken.The equation, P=E/t, where E is the amount energy used to do the work, means the same thing.The unit for Energy is the Joule (J), and the unit for time is the second (s).Therefore, you should see that the Watt is equal to 1 Joule (J) per second (s).There is also electrical power which should be considered, and there are a few different formulae depending on whether voltage, current or resistance are being considered.Electrical power is equal to the amount of current times the voltage, or P=IVAlso, electrical power is equal to the current squared times the resistance, P=I2RThere are other formulae for the average electrical power of a sinusoidal voltage, but this is outwith the scope of this answer.

The unit of power is then the watt,which is equal to 1 Joule (J) per second (s).Electrical PowerThere are a few different formulae depending on whether voltage, current or resistance are being considered. Electrical power is equal to the amount of current times the voltage, or P=IV. Electrical power is also equal to the current squared times the resistance, P=I2RThere are other formulae for the average electrical power of a sinusoidal voltage, but this is beyond the scope of this question.
If it's a simple resistive circuit, or a D.C. circuit, 1 kVA = 1 kW. Generally, it depends on your power factor. Since real power, P, is equal to the total power, S, multiplied by the power factor, p.f. Power factor is the cosine of the angle between the current and the voltage, O. So, P = S * cos(O)
P = (E2)/R = 81/9 = 9 watts
The relation is:P = I2RWhere:I is the current (for example, in amperes)R is the resistance (for example, in ohms)P is the power (energy per second) converted from electrical energy to heat. If the current is in amperes and the resistance in ohms, then power is in watts (equal to joules/second).

if the question were 81 S in a S P the answer would be 81 Squares in a Sudoku Puzzle so the extra S letter is a mystery unless 81 Squares in a Standard Sudoku Puzzle as there are other variations
dKE/dt = P= F.v Where KE is Kinetic Energy and P is Power.
Average power equals Work divided by time. P= W/t
