Use these equations here for this one. simply re-arrange to solve for the value you are missing:
I = current
E = volts
R = resistance
Power = watts

Equations
E = I x R
Power = I x E
Power = I^2 x R
Power = E^2 / R

Solving for I = 1.16Amps

What are the basic rules of basketball? Are the rules different for men’s versus women’s competition?
Vlad [161]

The 5 main rules are two teams of five players each try to score by shooting a ball through a hoop elevated 10 feet above the ground. The game is played on a rectangular floor called the court, and there is a hoop at each end. The rules are basically the same but the women's ball is one inch smaller than the mens ball.

A student wants to determine the impulse delivered to the lab cart when it runs into the wall. The student measures the mass of
forsale [732]
Impulse = Force * times and also Impulse = change in momentum.

Given that the mass does not change, change if momentum = mass * (final velocity -  initial velocity)

Given that you know mass and initial velocity (which is the velicity before the cart hits the wall) you need the final velocity (which is the velocity after the cart hits the wall).

Answer: the velocity of the cart after it hits the wall.
