The power of the machine can be calculated using the formula Power = Work/Time. Given that Work = Force x Distance, and the force required to lift the object will be its weight (N), the power can be calculated using the force (weight of object) and the distance it is lifted in the given time frame.

What is the power of a machine that does 1500 joules of work in 30 seconds?
The power of the machine is 50 watts. Power is calculated by dividing the work done (1500 joules) by the time taken to do the work (30 seconds).
How much is power output of a machine that lifts a 500kg object through a height of 20m in a time of 60s?
The work done by the machine would be the force required to lift the object multiplied by the distance it was lifted, which is 500kg * 9.81 m/s^2 * 20m = 98100 J. The power output would then be work done divided by time taken, which is 98100 J / 60 s = 1635 W or 1.64 kW.
What is the work done by a machine on an object?
The work done by a machine on an object is the transfer of energy that results in a change in the object's position, speed, or shape. It is calculated by multiplying the force applied by the machine on the object by the distance the object moves in the direction of the force. Work is typically measured in joules (J).
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.
Can a machine multiply power?
Yes, a machine can multiply power by increasing the force applied to an object or by increasing the speed at which work is done. Machines such as gears and pulleys are examples of mechanisms that can multiply power.
A building crane lifts a 1500lb steel beam to a height of 45ft in 10 seconds find the power?
150W

What is measured by the power of a machine?
Power is the amount of work a specific machine can do over a period of time. Work is the product of force and the distance an object travels as a result of that force. A more powerful machine can effect changes in velocity of an object more rapidly than a less powerful machine.

If it takes 726 watts of power to move an object 36 meters in 14 seconds, what is the mass of the object?
two watts a second
Can the power be increased if the same force acted over 50 seconds?
Yes, if the velocity of the object is increased.
Can a machine multiply power?
Yes, a machine can multiply power by increasing the force applied to an object or by increasing the speed at which work is done. Machines such as gears and pulleys are examples of mechanisms that can multiply power.
How do you get the medalion on time tangled island?
first, you have to go to the elevator which is simply a large object at the right of the river. wait for some seconds and go in it (simply walking left) then immediately jump and go neat the object that lifts you. Soon another train comes at the top and jump in it and then jump at the top and jump at the object that lifts you. you should end up in the geothermal energy inc. ( if you're in wind power tower you should jump to the left with the help of the gliders) then walk to the left, not jump, walk. On the trees they'll be an object jump on it. It will take you up and then jump to the left and enter on the top right floor there is a person he is you 50 years in the future he will give you the medallion.
What power is used by a machine to perform 800 joules of work in 25 seconds?
Power = energy/time During those 25 seconds, the machine is doing work at the rate of 800/25 = 32 watts. We don't know how much power the machine must consume in order to perform work at that rate, but we know it's more than 32 watts.
An object is lifted 2 m in 5 seconds by a force of 100 N.?
The work done to lift the object is 200 J (Work = Force x Distance). The power exerted to lift the object is 40 watts (Power = Work / Time).
