How do you figure square footage of an area from total perimeter?
Triangle Area = ½base × height Square Area = length of side to the power of 2 Rectangle Area = breadth × height Parallelogram Area = breadth × height Circle Area = πrto the power of 2
What is the power if 35N force 5 Meters and takes 19 seconds to push?
Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
How many ms are in 6.7 seconds?
6.7 times 10 to the -3 power
During a winter storm an entire town lost power for 2.6 hours How many seconds is this?
2.6 hours = 2.6*60 minutes = 156 minutes = 156*60 seconds = 9360 seconds.
How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
A building crane lifts a 1500lb steel beam to a height of 45ft in 10 seconds find the power?
150W
A weightlifter raises a 90-kg barbell from the floor to a height of 2.2 m in 0.6 s What was his average power output during the lift?
42
A weightlifter expends 294 W of power lifting a weight to a height of 2 m in 10 seconds What mass has he lifted?
assume a = 10(m/s)/s power (w) = energy change/time 294 = (mass * 10 * 2)/10 then mass = (294*10 )/ (10*2) = 147kg
A machine lifts a load of 240-kilograms a distance of 120-meters in 45-seconds. How much power is generated by the machine?
If you multiply the weight (mass x gravity) by the height, you get the energy required. (Note: gravity is about 9.8 newton / kilogram.) You then need to divide that by the time, to get the power.
A weightlifter raises a 90 kg barbell from the floor to a height of 2.2 m in 0.6 s What was his average power output during the lift?
power = force x velocity velocity = distance/time = 68 x 11/3 = 2.2/0.6 = 249.3 Watts = 11/3
An elevator lifts five passengers 30 meters in 24 seconds the power is 15000 watts what is the total weight of the elevator and passengers?
12,000 N, since force is equal to weight in this situation
What is the number one rated brand of wheelchair platform lifts?

How much power is needed to lift the1 piano and 1 floor in ten seconds?
The answer depends on the mass of the piano and the height of the floor.
How much power is needed to lift the 200-n object to a height of 4m in 4 seconds?
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts
What power is use to operate the Eiffel tower?
The lifts are electric.
If an elevator motor lifts a load of 10 slugs through a distance of 20 feet in 8 seconds how much power is the motor producing?
The power output would be corralated with the gearing of the motor, but assuming a perfect 1:1 ratio you would have a force of 25lbs, and a power output of 1600 watts.
