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.
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 input energy of a blender?
The input energy of a blender refers to the electrical energy consumed by the blender during operation. It is measured in watts (W) and indicates the amount of power required to run the blender. The input energy can vary depending on the blender's power rating and the duration of its use.
What is the conversion from joules of energy to watts of energy?
Power (watts) is a measure of energy transfer over time, while energy (joules) is a measure of total work done. The formula to convert energy in joules to power in watts is: Power (watts) = Energy (joules) / time (seconds).

A blender has a power of 0.3 kW. It is used to make a fruit smoothie, which takes 50 seconds. How much energy is used Give your answer in kilojoules.kJ?
To calculate the energy used by the blender, we first convert the power from kilowatts to watts: 0.3 kW = 300 watts. Then, we use the formula Energy (in joules) = Power (in watts) x Time (in seconds). Plugging in the values, we get Energy = 300 watts x 50 seconds = 15,000 joules. Finally, to convert joules to kilojoules, we divide by 1,000: 15,000 joules ÷ 1,000 = 15 kJ. Therefore, the blender uses 15 kilojoules of energy to make the fruit smoothie.
How long does it take to perform 750 Joules of work with 30 watts of power?
25 sec.
How much power is needed to perform 600 Joules of work in 120 seconds?
7.5 watts
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 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 much power is needed to perform 900 Joules of work in 90 seconds?
Power is energy per unit time. So, the required power is 900/90 = 10 Watts.
What is the input energy of a blender?
The input energy of a blender refers to the electrical energy consumed by the blender during operation. It is measured in watts (W) and indicates the amount of power required to run the blender. The input energy can vary depending on the blender's power rating and the duration of its use.

Power (watts) is a measure of energy transfer over time, while energy (joules) is a measure of total work done. The formula to convert energy in joules to power in watts is: Power (watts) = Energy (joules) / time (seconds).
What does power 200 joules mean?
Power represents the rate at which work is done or energy is converted. In this case, a power of 200 joules means that 200 joules of energy is being transferred or converted every second.
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.
