What is after giga joules?
One kilowatt-hour of electricity is 3.6 megajoules. The gigajoule (GJ) is equal to one billion (109) joules. The petajoule (PJ) is equal to one quadrillion (1015) joules.
How much energy is a billion joules?
An average bolt of lightning, striking from cloud to ground, contains roughly one billion (1,000,000,000) joules of energy. This is no small amount, enough to power a 60-watt lightbulb for six months plus a forgotten open door refrigerator for a day.
How powerful is an Exajoule?
1 Exajoule: Energy of a quintillion joules. 1 Exajoule is equal to 1018 joules.
How many joules does it take to kill you?
Under certain conditions, 10^-18 joules can kill a human. Normally this would be imperceptible. However, if this energy comes in the form of a photon, it is enough to ionize DNA molecules, causing mutations.
What can 1 joule of energy do?
One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.
How many joules can a human punch?
The kinetic energy of a punch varies greatly. While beginners might only be able to muster a measly 37.5 joules of energy, experts can deliver over 400 joules, an amount roughly equal to getting shot by a handgun!
Is 1 joule a lot?
While the joule is the SI base unit for energy, when speaking in real-world terms, we often use the kilowatt-hour (kWh) instead. This is due to the fact that a joule is an extremely small amount of energy. To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it.
What is the highest amount of energy?
Carbohydrates has the highest amount of energy.
How many joules does a house use per day?
Or about 248 mega-joules/day. In another answer, user said 11,000 kwh per year was average. He was a little sloppy with his math, but this works out to 108 mega-joules per day. 11,000 hours is 11,000 x 3,600 seconds which is 396,000,000.
Is 1000 joules a lot?
Joules are a measure of energy; Watts are a measure of the rate of energy generated or consumed. A Watt is defined as one joule per second. So if your 1000 Joules flowed in one second, the power would be 1000 Watts or 1 kW. A unit with up to 1000 joules of surge protection is adequate for these small electronics.
How many joules is dangerous?
How many joules is dangerous? Greater than 10 Joules is considered hazardous. Greater than 50 Joules is a lethal level.
How many joules is deadly?
Henderson states, according to long established principles, an object which impacts a human is considered 20% chance of being lethal, with a head strike, if its kinetic energy is greater than 80 Joules. 90% chance of being lethal, with a head strike, it its kinetic energy is 150 Joules.
Which is the most powerful release of energy?
The most powerful energy release per unit mass is a matter-antimatter reaction. All of the matter/antimatter that goes into this reaction is converted to energy, 100% mass to energy conversion. In a nuclear fission reaction, complete fission should yield about 0.090% mass to energy, depending on the specific materials uses.
How much energy does a nuclear bomb release?
Chicago: World Book. 1999. 597. “Nuclear explosive devices can have a wide variety of yields. Some older bombs had yields of about 20 megatons, or 1540 Hiroshima bombs. A megaton is the amount of energy released by 1 million short tons (907,000 metric tons) of TNT. Today most nuclear devices have yields of less than 1 megaton.”
Why are there so many energies in the universe?
There are so many energies in universe such as nuclear energy, solar energy, cng wind power etc but gravitational energy or force of the planets & stars is unique because this invisible energy is found without intervation of human & far away from our sense organs. We can’t see hear smell taste touch or feel it.
Which is the most powerful energy in the universe?
If you want to look at the most energy released from an even, you can start with the Big Bang of course. That released everything in this universe, all at once. No separate piece is more energetic than the whole. For things that are still happening that we know about, I’d have to go to the collision of black holes.
