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.
10 joules per second = 10 watts
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.
To melt 1 gram of ice at 0°C, it requires 334 joules of energy. So for g grams of ice, the energy needed would be g multiplied by 334 joules.
It takes 4.184 joules of energy to change the temperature of 1 gram of water by 1 degree Celsius.
The amount of joules needed to drive a car 1 mile can vary depending on several factors such as the weight of the car, its efficiency, and the driving conditions. On average, it takes about 133,000 to 175,000 joules (30 to 40 kcal) to propel a car weighing around 2,000 pounds for a mile under normal conditions.
well then all you have to do is divide here i have a sort out just for you an examplepower (in watts) = work divided by timeor for you smart ones:power=joules divided by time or sec.Following the above:Power (in watts) * time (seconds) = joules100,000 joules = 100,000 watt / seconds => (100,000 Watt / seconds ) * (50 minutes, or 3000 seconds) = 33.3 watts.
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
Approx 2940 Joules.
2,26 Kj are necessary
10 joules per second = 10 watts
It had better be in joules. Watts and volts are not units of energy. yes, but how many as in ? joules/sec
10 joules per second = 10 watts
10,000
Voltage is electrical pressure and Joules is a power rating so other info is needed
100000
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.
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.
