How does watt and joule relate?
The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.
How dou you convert joules to watts?
Joule is a unit of energy, watt is a unit of power. Power is energy per time unit. In a way, those are incompatible units, but if you know in what time you spend a certain amount of Joule, you can convert to Watt, and vice versa. For example, if you use 200 Joule in 2 seconds, that is 200/2 = 100 Joule/second, or 100 Watts. Or, if a light-bulb uses 35 Watts, that is 35 Joules every second, so in an hour it will use 35 x 3600 = 126000 Joules, or 126 KJ.
What is gravitational potential energy for 200 n and 100 meter cliff?
GPE = mgh = (mg)*h = 200*100 = 20,000 Joules.
The average weight of a second grader?
average.. is about 100.
How much energy does it take to raise 100KG by 1 meter per second?
The amount of energy required is found by the following equation E=mgh Energy=mass*gravity*height m=100Kg g=9.81m/s^2 (Standard gravity on Earth) h=1.00m so, E=(100)*(9.81)*(1.00)=981J The second is irrelevant when determining energy, it would take 981J to lift it in 1 second or in 1 year. However, power takes time into consideration as it is the rate at which work is performed, P=E/t Power=energy/time =981/1=981W 100 Joules I believe. = =
What is the power of a light bulb that converts Electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
What is the power of light bulb that converts electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
How many joules of light energy are in 1440 watts of electrical energy?
To calculate the energy in joules, you can use the formula: energy (joules) = power (watts) × time (seconds). If you have 1440 watts of electrical power and want to calculate the energy in joules for a specific time period, you would need to know the time duration in seconds.
The power of a light bulb that converts electrical energy at a rate of 100 joules per second is what?
The power of the light bulb is 100 watts since 1 watt is equal to 1 joule per second.
How much energy does a 100-w light bulb use in 10 s?
Power = energy / time, in SI units: watts = joules / seconds. Solving for energy: Joules = watts x seconds.
How many joules are in 100 watts?
There are 100 joules in 1 watt-second, so in 1 second, there would be 100 joules per watt. Therefore, in 100 watts, there would be 10,000 joules.
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
To find the number of photons being radiated per second, you need to calculate the energy of each photon first. Since the light bulb emits 100 watts (100 joules per second), and each photon has an energy of about 4.86 x 10^-19 joules for visible light, you can divide the total energy emitted per second by the energy of each photon to find the number of photons emitted.
How many joules of energy does a 100 watt bulb require each second?
A 100-watt bulb requires 100 joules of energy per second. This is because power is a measure of energy consumption per unit time, so a 100-watt bulb consumes 100 joules of energy every second it is turned on.
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
In 2 seconds, a 100 Watt light bulb consumes 200 Joules of electrical energy from the electrical supply (100 Watts * 2 seconds = 200 Joules).
The power of a light bulb that converts electrical energy at a rate of one hundred joules per second is?
1 joule is the energy equal to 1 watt for 1 second.100 joules = 100w for 1 second.A 100 watt light bulb converts 100 joules of electrical energy into heat and light every second.Only about 1% of this is useful light, the rest is wasted as heat.AnswerPower is defined as the rate of doing work. As work is expressed in joules (J), it follows that power is measured in joules per second (J/s) -however, in SI, this is given a special name: the watt (W).So one joule per second is exactly equivalent to one watt. Therefore, 100 J/s is exactly equivalent to 100 W.
100 joules of heat plus to system of 60 joules of work?
The total energy added to the system is 160 Joules, comprising of 100 Joules of heat and 60 Joules of work. This increase in energy will lead to a rise in the system's internal energy.
What mechanical work can be done using 100kW energy?
100 kW is not an energy, it is a power. It is the same as 100 kJ/sec (100,000 joules/second. The 100 kW - or 100 kJ/second - can be converted to 100 kW of mechanical power - or less, depending on the type of energy, and how much is wasted.
