What is the power output of A man who is able to lift 250 kg 2.00M in 2.00S?

Raising 250 kg by 2 meters = 500 kgm-meters = 500 Joules of potential energy added to the load.
If this maneuver is accomplished in 2 seconds, then the rate of delivering energy to the load is
500/2 = 250 joules per second = 250 watts = roughly 1/3rd horsepower.

How does force affect power output?
Force affects the speed of power output. If the driving force is slow, the speed of power output will also be sluggish. Alternatively, if the driving force is fast, power output will be able to match the speed.
What is a 1 dB compression point?
Devices, such as amplifiers can't be linear over all input values. At some point they just can't output the required output power. I.e. an amplifier that increases input power by a factor of 10, may not be able to amplify a signal that comes in that is, let's say 10 watts. The point where the device is outputing 1 dB less POWER (which is roughly running at 80%) than it should is the 1 dB compression point. So lets say a 10 watt signal is input, and that the signal should be amplified by a factor of 10, and should output 100 watts. Let's also say the system output power is actually 1 dB down from the expected value and outputting roughly 80 watts, 10 watts is the input 1 dB compression point.

What is resonating frequency?
It is a the RF output of a transmitter that is tuned to a distanced receiver, it have to be in resonance with the transmitter signal to be able to receive the signal
How is wind power stored once it is recovered?
Wind power isn't stored. It is immediately generated into electricity that goes straight into the power lines. This is why there has to be power lines in and area for it to be able to have a wind farm.
What is the output force exerted by a move-able pulley if the input force is 50 N?
The answer will depend on the configuration of the rope as it goes around the movable pulley and the fixed roller.
How does force affect power output?
Force affects the speed of power output. If the driving force is slow, the speed of power output will also be sluggish. Alternatively, if the driving force is fast, power output will be able to match the speed.
What is horse power of a 415 volt 3 phase 7.5 kW electric motor?
Motors are rated according to their output power, never their input power. This is because it is the output power that determines the load the motor will be able to handle. The output power, of course, is lower than the input power due to the machine's losses.In North America, the output power is generally expressed in horsepower, whereas its input power is measured in watts. In the rest of the world, the horsepower is considered obsolete, so both the output power and the input power are measured in watts.As there are 746 W to the horsepower, your 75 kW output motor would be equivalent to approximately 100 horsepower.
How much electricity producer in chashma nuclear power plant in pakistan?
Chashma Unit I is operating with a power output of 300 MWe. Chashma Unit II is undergoing testing, and is able to produce 300 MWe. Chashma Units III and IV are under construction or planned with a power output of 340 MWe each.
What must you match when purchasing a power supply?
The equipments power requirements, and the mains voltage. The output of the power supply must be able to deliver the correct voltage to the equipment, at the appropriate wattage. Additionally, it should be capable of operating on the supplied mains voltage and wattage.
Is a cellphone a input or a output?
Cell phones have both input and output functionality, like being able to speak into and hear out of or being able to type text and see it on the screen.
Which camcorders can output in DivX format?
Not many camcorders these days are able to output in DivX, but there are some Canon ones that can, I believe.
Would a blue star still be able to possess a habitation zone like our own Sun?
As far as I know, the "habitable zone" is defined in terms of the expected temperature. So, what matters mainly is not the star's color, but its total power output (brightness). In any case, whatever the star's brightness (power output), it is to be expected that there is a certain distance from the star at which the temperature is appropriate.
What is power amp?
Hi, A power op-amp is an op-amp that has the capability to deliver higher output power than the more common garden variety of op-amps. Some of them are able to handle 150 watts of output or even higher. They're also quite expensive, too. Mainly they're used in industrial control, but probably could be used for some audio applications. Hope this helps, Cubby
What is a printers output rate?
The speed by which it is able to produce printed sheets.
Choosing Power House Generators?
If you are looking for performance, then you need to make sure that you by a generator that can give you the output you need while saving you on fuel. Power house generators are a great thing to look into if you want to have a great balance between energy output and fuel input. These generators are able to handle large loads when you need them without using up tons of precious fuel in the process.
What is 200m squared?
200 ^2 = 40000 You should be able to do the remaining. Note: distance cannot be used to measure area Area = distance ^2 (units wise)
Why need to stabilize amplifier?
the function of amplifier is to keep amplifying .............that is to keep multiplying the input with input to obtain larger output. hence , if this process is carried on indefinately then the system at a certain stage will not be able to retain its stability coz high of high power or output .thus it is necessary to stabalize by it by using. limter ' or threshold vaue
