Watt- second -or kilowatt means?
You should think of "watt" as a rate or speed ... it's the speed of using energy, but instead of speed, it's called "power". 1 watt means that 1 joule of energy is being used every second. 1 watt-second means the amount of energy used in one second, when it's used at the rate of 1 watt. In the last paragraph, we just said that this is 1 joule of energy. "Kilowatt" is also a rate at which energy is used. It's 1,000 joules per second, or 1,000 watts.
How is power ralated to energy?
Power is the rate of change of energy ... The amount of energy generated or used, divided by the time to generate it or use it. If you're using 1 joule of energy every second, then you're using 1 watt of power.
Where would geothermal energy be used?
It is used every day in Iceland.
What is the power of an electrical cable car that uses 3500 joules every second?
3500W, or 3.5kW Power is measured in Watts; one Watt is 1 joule of energy converted/used per second. So, 3500 joules a second is 3500 Watts.
How does energy transfer in fans?
The energy transfer when a fan is used is known as forced convection.
How many energy do we use in a year?
Kilojoules of energy is used every year. Energy consumption is very high.
How much is a watt?
A watt is one joule of energy used every second. In electronics, applying 1 volt across a 1 ohm resistor will produce 1 W of heat.
How many energy levels are used in Boron?
it is in the second period. so boron has 2 energy levels
What is the molecule for energy?
It is commonly known as ATP, and used in the mitochondria.
What is the term used to describe the amount of energy released in an earthquake?
The energy is known in Joules and it can be compared to the explosive energy of TNT.
What are Kinetic and Potential energy?
Kinetic energy is the energy that make things move. They are known as the "Movement Energy". Potential energy is the energy stored in object, waiting to be used.
What year was nuclear energy used?
Every year since 1945
