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 power of a bulb that uses 3 jolts every 10 seconds?
Power is calculated as energy consumed per unit time. If a bulb uses 3 joules of energy every 10 seconds, its power can be calculated using the formula: Power (in watts) = Energy (in joules) / Time (in seconds). Therefore, the power of the bulb is 3 joules / 10 seconds = 0.3 watts.
Does 15 amps equals 1500 joules?
No, 15 amps does not equal 1500 joules. Amperes (amps) measure electric current, while joules measure energy. To relate them, you need to know the voltage (in volts) and the time (in seconds) for which the current flows. The formula for electrical energy is ( \text{Energy (Joules)} = \text{Power (Watts)} \times \text{Time (seconds)} ), where power is calculated as ( \text{Voltage (Volts)} \times \text{Current (Amps)} ).
What formula is e equals pt?
The formula for energy. E is for energy(Units = Joules) P is for power(Units = Watts) T is for time(Units = Seconds)
Find the work you do when you exert a force of 40 N to run a distance of 18 m in 4 seconds?
The work is Work= FD= 40x18= 720 Joules. The power is W/seconds = 720/4= 180 Watts.
How much power is needed to perform 600 Joules of work in 120 seconds?
7.5 watts
How long does it take to perform 475 Joules of work with 25 watts of power?
To calculate the time it takes to perform 475 Joules of work with 25 watts of power, you use the formula: time = work / power. In this case, time = 475 Joules / 25 watts = 19 seconds. So, it will take 19 seconds to perform 475 Joules of work with 25 watts of power.
How long does it take to perform 500 Joules of work with 25 watts of power?
To find the time taken to perform 500 joules of work at a power of 25 watts, you divide the work by the power. In this case, 500 Joules / 25 watts = 20 seconds. Therefore, it would take 20 seconds to perform 500 Joules of work with 25 watts of power.
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 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.
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 150 seconds?
Power = Work / time= 600 J / 150 secPower = 4 J/s or 4 Watts (1 Watt = 1 J/s)
How much power is necessary to do 60 joules of work in 20 seconds?
The power required to do 60 joules of work in 20 seconds is determined by the formula: Power = Work / Time. Therefore, Power = 60 joules / 20 seconds = 3 watts. So, 3 watts of power is necessary to do 60 joules of work in 20 seconds.
What is the time taken by a body to perform 440 Joules of work at rate of 11 watt?
11 watts = 11 joules per second(440 joules) / (11 joules per second) = 40 seconds
How long does it take to perform 480 Joules of work with 20 watts of power?
To calculate the time taken to perform work with a certain amount of power, you can use the formula: time = work / power. In this case, the time taken to perform 480 Joules of work with 20 watts of power would be 480 J / 20 W = 24 seconds.
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 us necessary to do 50 joules of work in 5 seconds?
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.
