How many joules does one ton of coal produces?
One ton of coal produces approximately 24 million joules of energy when burned.
How many joules of energy does a 1 Newton book gain when it is elevated 4 meter?
The gravitational potential energy gained by lifting a 1 Newton book 4 meters is 4 Joules. This is calculated by multiplying the force (1 Newton) by the distance (4 meters) to get the energy in Joules.
Cardioversion of 200 joules - how many watts?
To calculate the power in watts, simply divide the energy in joules by the time taken to deliver that energy. If 200 joules of energy are delivered in 0.2 seconds during cardioversion, the power would be 200 Joules / 0.2 seconds = 1000 watts.
How energy is transferred from the sun to the earth?
The sun transfers energy to earth gravitationally and electrically. Energy Gravitationally = - GmeMs/r, Electric Power is transferred by Solar flux S= 4/3 Kwatts/m^2. This produces around 88E21 Joules per day.
How many joules in grass?
Grass does not have a fixed amount of joules as its energy content can vary based on factors like species, maturity, and growing conditions. However, grass mainly contains energy in the form of carbohydrates, which provide about 4 calories (approximately 16.7 joules) per gram.
How many joules of potential energy does a 1-N book gain when it is elevated 4 m?
The potential energy gained by the book can be calculated using the formula: potential energy = mass * gravity * height. The mass of the book is needed to calculate the exact amount of potential energy gained. Assuming a mass of 1 kg, the potential energy gained would be approximately 39.2 J.
How many calories equal to 84 joules?
1 cal=4 joule. 84 joules=84/4=21 cal
How is the sun energy produced?
Nuclear fusion in the sun's core, where Hydrogen-1 is converted to Helium-4 plus energy.
A 20 kg mass is held 4 m above the ground What is the approximate potential energy of the mass with respect to the ground?
The mass' approximate potential energy at four meters is 784 joules.
How sun produces energy?
Nuclear fusion, converting hydrogen-1 into helium-4.
What power is consumed in a dc circuit of 28volts and 4 amps?
Power is voltage times amperes, so 28 volts and 4 amperes is 112 watts. The reason for this is that voltage is actually joules per coulomb, and amperes is actually coulombs per second. Multiplying them together produces joules per second, which is the definition of watts.
How much energy gets from the sun?
The sun gives the earth 4/3 Kwatts/m2 . The sun radiates out 377e24 watts or Joules/second.
