How much power in watts is needed to cut a lawn in 50 minutes if the work involved is 100000 joules?
The power needed to cut a lawn in 50 minutes, given that the work done is 100,000 joules, can be calculated by dividing the work by the time. 100,000 joules of work in 50 minutes is equivalent to 33.33 watts of power.
How much power is used (in watts) when 120 joules of work is done in 1 minute?
Power is the rate at which work is done, given by the formula Power = Work/Time. In this case, Power = 120 Joules / 60 seconds = 2 Watts.
How much power in units of horsepower is generated from 79.3 Joules of work done in 37.2 minutes?
First, convert 37.2 minutes to seconds (37.2 minutes x 60 seconds/minute = 2232 seconds). Then calculate power using the formula Power = Work / Time. So, Power = 79.3 Joules / 2232 seconds = 0.0355 Watts. Finally, convert Watts to horsepower (1 horsepower = 746 Watts), so 0.0355 Watts = 0.0000476 horsepower.
If 478 Watts of power are used in 14 seconds how much work was done?
The work done can be calculated using the formula: work = power × time. Substituting the given values, the work done would be 478 Watts × 14 seconds = 6692 Joules.
Why power is measured in minutes not in seconds?
Power is typically measured in watts, which represent the rate at which energy is expended over time. Since power is a measure of energy per unit time, it is commonly expressed in terms of minutes to provide a more practical and meaningful representation of how much work can be done over a certain period. Additionally, using minutes allows for easier comparison and calculation of energy consumption over longer durations.

How much work can a 500 watt electric mixer do in 2.50 minutes?
The work done by an electric mixer can be calculated by multiplying the power (500 watts) by the time (2.50 minutes) in seconds. First, convert the time to seconds: 2.50 minutes = 150 seconds. Then, calculate the work done: Work = Power x Time = 500 watts x 150 seconds = 75,000 joules.

Power is the rate at which work is done, given by the formula Power = Work/Time. In this case, Power = 120 Joules / 60 seconds = 2 Watts.
How many watts is 150 watts after 5 minutes?
150 watts remains 150 watts after 5 minutes as power is typically constant if not explicitly stated otherwise.

How much power is used when 600 J of work are done in 10 seconds?
The power used would be 60 watts. This can be calculated by dividing the work done (600 J) by the time taken (10 seconds), resulting in 60 watts.
A bag of books took 3 minutes to move. You did 12900 J of work. How much power was required to move the bag?
The power required to move the bag of books can be calculated by dividing the work done (12900 J) by the time taken (3 minutes = 180 s). So, the power required is 71.67 watts.
How much power does a 8-pin power supply connector provide?
300 watts
What is a measured of how much work can be done in a certain amount of time?
Power is a measure of how much work can be done in a certain amount of time. It quantifies the rate at which work is done or energy is transferred. Power is typically measured in units such as watts (W) or horsepower (hp).
A measure of how much work can be done in certain amount of time is called?
The measure of how much work can be done in a certain amount of time is called power. Power is the rate at which work is done or energy is transferred. It is commonly expressed in watts (W) or horsepower (hp).
