Power is measured in j per what?
Power is measured in Joules per Kilowatt.
What is the energy used in one second when a bulb have 40Watts.?
The energy used by a 40W bulb in one second is 40 Joules. This is because power is defined as the rate at which energy is transferred or converted, so if the bulb consumes 40W of power in one second, it uses 40 Joules of energy in that time period.
What is the unit measure for power?
The watt, which is equal to joules/second.
How many watts is needed to melt one pound of aluminum?
How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.
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
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).
The amount of power needed to do 10 joules of work in 1 second is?
10 joules per second = 10 watts
How much power in needed to produce 1700 Joules in 5 seconds?
The power needed can be calculated using the formula: Power = Energy / Time. Plugging in the given values, the power required to produce 1700 Joules in 5 seconds is 340 Watts.
What is the amount of power needed to do 10 joules of work in 1 second?
10 joules per second = 10 watts
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 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 is needed to perform 600 Joules of work in 120 seconds?
7.5 watts
How many joules are in 1500 grams?
Voltage is electrical pressure and Joules is a power rating so other info is needed
How much power is needed to do 648 joules of work in 100seconds?
Power is calculated using the formula P = W / t, where P is power, W is work done, and t is time taken. In this case, you would calculate power as 648 / 100 = 6.48 watts. Therefore, 6.48 watts of power is needed to do 648 joules of work in 100 seconds.
How much power is needed to do 10 joules of work 1 second?
Approximately 0.01341 horsepower or 0.01 kilowatts.
How do you freeze the clock on super power island?
press space bar but it only freezes time for 10 secounds and it takes five secounds to reset so you can uses it again.
How long would it take a machie to do 5000 joules of work if the power rating of the machine is 100 watts?
To calculate the time taken to do 5000 joules of work with a 100-watt machine, you can use the formula: time (seconds) = work (joules) / power (watts). Therefore, the time taken would be 5000 joules / 100 watts, which equals 50 seconds for the machine to complete the work.
