50J /10 s =5 W
There are 5 minutes and 50 seconds
1 calorie = 4.1858 joules 1 joule = 0.2389029576186153 calories As an example, convert 5 calories to joules. 1 calorie = 4.1858 joules, therefore 5 calories = 4.1858 x 5 joules = 20.929 joules. So when converting calories to joules, multiply the number of calories by 4.1858 to give you the number of joules.
10 Min's - 5 Min's = 5 Min's - 50 Sec's = 4 Min's 10 Sec's - 15 Sec's = 3 Min's 55 Sec's 3 Minutes and 55 Seconds. ------------------- Interesting math, but the correct answer is still 4 minutes, 25 seconds. Why did you subtract the 15 seconds instead of adding it??
-50.
The power required to do 50 joules of work in 5 seconds is 10 watts. This is calculated by dividing the work done (50 joules) by the time taken (5 seconds), which equals 10 watts.
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
The power needed to do 50 joules of work in 5 seconds is calculated by dividing the work by the time, which equals to 10 watts. So, 10 watts of power is required to do this amount of work in the given time frame.
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.
If one were to do one hundred Joules of work in five seconds, he/she would have a power output of 20 Watts.
Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.
The amount of heat produced by the 100 W heater in 5 minutes can be calculated as follows: Power (in watts) = 100 W Time (in seconds) = 5 minutes * 60 seconds/minute = 300 seconds Energy = Power * Time = 100 W * 300 s = 30,000 joules So, the heater will produce 30,000 joules of heat.
Based on the formula, P = E/T , and 5 min is 300 seconds, 100 = E/300, E = 30000
as power=P=W/t=Fd/t=(10)(10)/10=10Watt
50J /10 s =5 W
B.) 10 Watts
Power is equal to work done divided by time, where work done is force multiplied by distance. In this case, the work done is 100 newtons * 10 meters = 1000 joules. Therefore, the power used would be 1000 joules / 5 seconds = 200 watts.
