What is the power of a CD player if it uses 60000 joules for 30 minutes assuming 100 percent efficiency?
Power = energy used/time to use itPower of this CD player = 60,000/(30 x 60) = 331/3 wattsThat solution doesn't depend on the player's efficiency ... you specifiedonly the energy it uses.But since you did mention the concept of efficiency, I'm compelled to add athought here: If you're describing the kind of CD player that you can carryin your pocket and listen to it on the bus, then 33 watts is an astronomicalpower consumption for it. You'd need to carry a back-pack full of batteries,and recharge them every few hours.If these are real figures, and the thing really does consume 33 watts in normaluse, then I hope it plugs into the wall, and drives a nice pair of speakers.
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.
What is the rate at which work is done?
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
5 plus 6x10 to the fourth power?
5 + 6*104=60000+5=60005
What Equation is used to determine power loss?
Power (Joules) = the square root of the voltage squared divided by the resistance
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 used when 600J of work are done in 10s?
60 W
What number equals 60000 when taken to the 6th power?
6√60000 ≈ 6.2569
How many joules of work can a quarter - horsepower air conditioning unit perform in ten minutes?
Convert to compatible units: convert horse-power to watts, and minutes to seconds. Then use the formula: work = power x time.
How many joules does a 800 watt toaster consume in 2 minutes?
Energy = power X time. 800W X 120sec = 96000J
How much work can a 500 watt electric mixer do in 2.50 minutes?
The work or energy in Joules is the power in watts times the number of second it runs for. So 500 watts for 150 seconds is 75,000 Joules.
One thousand watts of power used in 60 minutes is?
You have to multiply the power times the time, to get energy. In this case, you get either 1 kilowatt-hour or 3,6 millions watt-seconds (joules).
An electric jug full of water needs 480000 joules to bring it to boil The element power is 1 Kilowatt how long will the jug take to boil?
1 kilowatt = 1000 joules per second, so it will take 480 seconds. (8 minutes).
What is the speed at which energy is transfered?
That is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = WattsThat is called "power". Energy / time = powerIn SI units: Joules / seconds = Watts
How much power in watts will an led bulb consume if its energy is 6 joules?
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
How do you calculate power if don't know joules?
Well, the first step is to learn joules and you'll be set!
