How many seconds would it take a 1200 W motor to raise a 9800 N to 10 m high?
Calculate the amount of potential energy required. Then divide by the power.
An electric drill has an efficiency of 75 percent. If the motor has a power input of 700 watts and is run for 30 seconds. How much actual work is done. How would I get a kilojoules answer?
Power input = 700 WEfficiency = 75% so power output = 75% of 700 = 525 W Time = 30 seconds => Work done = 525W * 30s = 15750 W.s = 15750 Joules = 15.75 kiloJoules.
Why can a car accelerate from 0 to 60 in less than 4 seconds?
Most likely, the motor can not handle the horse power it needs. Some cars are built to achieve that. But they are cars that are built for racing, or they have more horse power than the average family car.
How long would it take a 500 W electric motor to do 1.50 x 105 J of work?
To find the time it takes for a 500 W electric motor to do (1.50 \times 10^5) J of work, we can use the formula: [ \text{Power} = \frac{\text{Work}}{\text{Time}}. ] Rearranging gives us: [ \text{Time} = \frac{\text{Work}}{\text{Power}} = \frac{1.50 \times 10^5 \text{ J}}{500 \text{ W}} = 300 \text{ seconds}. ] Thus, it would take 300 seconds, or 5 minutes, for the motor to perform that amount of work.
Why load angle is positive for generator and negative for motor?
simply put a motor consumes power and a generator produces it. reactance of a generator = - reactance of a motor
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.
What amount of work can a 600 W motor do in 4 minutes?
(600 Watts) x (4 minutes) = (600 joules per second) x (240 seconds) = 144,000 joules =144 kilojoules
How many watts of motor are required for 30 kg material?
If it's to lift 30 kg, it depends how far it is to be lifted and how quickly the lift takes to complete. To lift 30 kg through 10 metres requires 30 x 9.8 x 10 joules of energy, that is 3000 Joules. To do that in 10 seconds needs 300 watts, which would be about half a horse power motor. To do it in 5 seconds the power would be 600 watts - a 1 horse power motor.
How much energy does the motor transfer every second?
The amount of energy that a motor transfers every second can be calculated by multiplying the power output of the motor by the time duration over which the power is being exerted. The unit of power is watts (W), and the unit of time is seconds (s). Therefore, the energy transfer per second can be expressed in units of joules per second, which is equivalent to a watt.
Is an airplane a motor or a vehicle?
An airplane is a VEHICLE. It's power is provided by a MOTOR.
Is your power into motor equal to your power out of motor at no load?
For a motor's output power to equal its input power, the motor's efficiency must be 100%. As no machine, particularly a rotating machine, can possibly achieve 100% efficiency, there is no condition under which its output power can ever match its input power.
How do you test a power window motor?
Disconnect wires from motor and check to see if you have power and ground going to motor--if so motor is bad if not have to check wiring and switch to that motor
How many seconds would it take a 1200 W motor to raise a 9800 N to 10 m high?
Calculate the amount of potential energy required. Then divide by the power.
How do you calculate 3ph AC motor power?
How do you calculate 3ph AC motor power?
Slip power in a induction motor?
slip power is a power which is develop by the induced voltage and current in an induction motor
Why does heater motor not work on a 1987 cariolet changed the motor have power to the rheostat?
The resistor has power going to it but, the resistor may be burned out and no power is coming out of it. Check for power at the blower motor connection.
How do you fix power window 2003 Chevy pickup?
remove door panel check to see if you are getting power and ground to motor. If so, bad motor--if no power to motor, check to see if you have power to switch if so ,bad switch--if not bad power feed to switch close but if the switch not on, you never get power to the motor.
