One motor has twice the power as a second motor. which motor does greater work for the same interval of time?

"Power" is the rate of doing work (delivering energy).
A motor that is operating at higher power is delivering more energy per second, so it does greater work for the same interval of time than the second motor.
Here's a note though: The rating marked on a motor is the power it's capable of delivering, but not necessarily the power it is delivering whenever it's running. If your two motors had the same loads on them, then they'd be operating at the samepower level and doing the same amount of work per second, even though one might be capable of handling a greater load.

What number is greater 10 to the power 390?
If you mean "greater than", you can raise it to a higher power.
How do you find work done with given time interval?
W = Integral [ Power dt ] t1 -----> t2
How many watts of power are expanded when a force of 1 newton moves book 2 meter in a time interval of 1 second?
Work = (force) x (distance) = (2 x 1) = 2 newton-meters = 2 joulesPower = (work)/(time) = 2 joules / 1 second = 2 watts
Will a larger sprocket increase speed?
Larger pinion (directly on motor) yes, but at lower torque (power/force) If its not connects directly to motor than it slows the rest of the series. Connected to motor (drive) it will spin at a set rate. The more teeth/larger circumference the more transferable energy. If the first is large, and the second is small, it will turn the smaller one many many more times per one revolution of the motor turn. Example, if motor gear has 100 teeth, and the second has 10 teeth. For every one motor rev, the secondary will have to turn 10 times creating speed. Hope this helps. I have a decade of rc and robotics experience, what are you trying to do?
What power is expended of 100 N box is lifted the distance 2 meters in 1.0 Sec?
The formula for power is: amount of work / time interval 200 J / 1 sec. The amount of power expended: 200 Watts
How much work can a motor with a power output of 25W do in one second?
A power output of 25W for one second is 25 joules. It is also 0.03 horsepower (electric motor scale)
Why is the number 36.2 x 10 to second power not written is scientific notation?
The mantissa must be a number in the interval [1, 10).
What is the most recommended motor to put on the Hyundai excel model 1992 to give you a great fell of power it will be greater if there is a motor with turbo?
you're an idiot
Which whole number values of x greater than 0 is the value x to the second power is greater then the value of 2 to the power of x?
' x ' = any whole number greater than ' 2 '.
What is the GCF of 3y to the second power and 24y to the third power?
If ' y ' is greater than ' 1 ', then [ 3y to the second power ] is. If ' y ' is less than ' 1 ', then 3 is.
Explain why 6.3 mutiply 10 to the second power is greater than 9.7 mutiply by 10 to the fourth power?
It isn't.
The amount of work done divided by the time interval the work required is?
The average power during the time interval.
What is the problem with using an electric motor to run a generator stepped up with transformers that is used to run the motor and give electricity for other uses?
It's all to do with the conservation of energy. The output power of the transformer cannot be greater than the input power from the motor used to drive your generator! In fact, it will be significantly lower than the power of your first motor due to the efficiency of the motor, of the generator being driven by that motor, and of the transformer. So if you then try to run the original motor from the output of your transformer, the energy-losses will simply accumulate, and the motor will not be able to run!
How many poles in a six thousand RPM motor?
It depends on the frequency. At 60 Hertz, with an ordinary two pole synchronous motor, you cannot have an RPM that is greater than 1800, so a six thousand RPM motor has to have a different power supply.
If a three phase induction motor runs at a speed greater than synchronous speed?
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
How do you solve for power if mass distance and time is given?
power=work done/time interval
Why do you connect a capacitor with an Ac motor?
The capacitor is used to create a second phase from the single phase power source and it is the interaction between these two phases that causes the motor to turn.
