∙ 15y agopower is how many Joules are used every second. So if we use 100J in 50s then we must be using 2J per second (you deivde everying by 50 to get that). Watt is the unit of power! (that's not a question) so our answer is 5 watts.

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)
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 does it take to do 104j of work in 60 seconds?
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
How long does it take to perform 450 Joules of work with 25 watts of power?
18 Seconds (:
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.
What is the power output of an engine that does 60 000 joules of work in 10 seconds?
60,000 joules per 10 seconds = 6,000 joules per second = 6,000 watts
How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
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 worker used 6000 joules of work to pull his sled 70 seconds what power does he need?
6000 joules / 70 seconds = 85.71 watts
Calculate the power in watts used if you exert 50 joules of work in 5 seconds?
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
Which of these has the most power?
an electric sander that does 5000 joules of work in 5 seconds
A power mower does 9.00 times 105 J of work in 0.0500h. what power does it develop?
You need to convert the time to seconds. Then, if you divide the work (in joules) by the time (in seconds), you will get the power in watts.
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 does it take to do 104j of work in 60 seconds?
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 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 needed to perform 600 Joules of work in 120 seconds?
7.5 watts
How long does it take to perform 450 Joules of work with 25 watts of power?
18 Seconds (:
