How much power is involved if 1800 joules of work are done in 1 minute?
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
Which of the situations involves more power200 Joules of work done in 20 seconds or 50 Joules of work done in 4 seconds?
Use the definition of power as energy / time (or the equivalent work / time). Do the calculation for both cases, then compare.
How much power in units of horsepower is generated from 79.3 Joules of work done in 37.2 minutes?
Power = energy/timeWatts = joules/seconds(79.3 joules/37.2 minutes) x (minute/60 seconds) = 0.03553 watt= 35.53 mW = +15.5 dBm (rounded)====================To answer the question:(79.3 joules/37.2 minutes) x (minute/60 seconds) x (horsepower/745.7 watts) = 0.0000476 HP (rounded)47.6 microhorsepower(power output of 47.6 microhorses)
If a person exerts 100 watts of power in 10 seconds. How much work was done?
If a human adult uses energy athe rate of 100 watts, or 100 joules per second, and sustains this rate for 10 seconds, the work done equals 1 kilojoule.
If A 100 kilogram man climbs a flight of stairs to a height of fourteen meter in ten seconds how much is the power and for the work done?
To raise 100 KG by 14 meters the work done is 100 x 9.81 x 14 = 13734 Joules. (9.81m/sec2 is the acceleration of a body in free fall, commonly called 'g') To do this work in 10 seconds means a power of 1373.4 Joules/second = 1373.4 watts
When calculating power what 2 pieces of information are needed?
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
How much power is involved if 1800 joules of work are done in 1 minute?
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.

How much power is used when 600J of work are done in 10s?
60 W

How much work is done using a 60-watt light bulb for 1 hour?
In terms of joules, the answer is 216,000 joules. First, you must convert 1 hour to seconds. 1 hr = 60 mins 60 mins = 3,600 seconds The formula for finding power can also be used to find work if power and time are provided. Power = Work/Time 60 watts =work/3,600 seconds To find this, multiply 3,600 by 60 3,600 X 60 = 216,000 The unit for work is joules, so the answer is 216,000 joules.use the power formula

If a human adult uses energy athe rate of 100 watts, or 100 joules per second, and sustains this rate for 10 seconds, the work done equals 1 kilojoule.
What is the rate at which what is done?
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
The amount of work done per unit of time?
Work done per unit of time is defined as power. In the metric system, this unit is a watt. In the standard system, it is horsepower.
If A 100 kilogram man climbs a flight of stairs to a height of fourteen meter in ten seconds how much is the power and for the work done?
To raise 100 KG by 14 meters the work done is 100 x 9.81 x 14 = 13734 Joules. (9.81m/sec2 is the acceleration of a body in free fall, commonly called 'g') To do this work in 10 seconds means a power of 1373.4 Joules/second = 1373.4 watts

What is the power when a 150kg block is lifted in 5 minutes?
The question cannot be answered without knowing the distance the block has been raised. work done (in Joules) = mass (in Kg) X gravitational constant (N kg^-1) X distance (in Meters) power (in watts) = work done / time (in seconds) So: power = 150 X 10 X (don't know) / 300 (seconds)
