If I've kept my units straight, that's about a megaton of TNT. Thermonuclear bombs and earthquakes are about all I can think of that release that amount of energy in a short time.
4 joules = about 1 ton of coal
A 1-newton book at 4 meters gains approximately 4 joules of potential energy.
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.
The mass' approximate potential energy at four meters is 784 joules.
Increase in the object's potential energy = (force) x (distance) = (200) x (4) = 800 newton-meters = 800 joulesPower = (800 joules) / (4 seconds) = 200 joules per second = 200 watts
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.
The potential difference is 1 volt = 4J/4C.
You need to multiply the force by the distance.
Nuclear fusion in the sun's core, where Hydrogen-1 is converted to Helium-4 plus energy.
Kinetic energy = (1/2)mv2, where m is mass and v is velocity.In this case, mass is 4 kg and velocity is 5 m/s, so K = (1/2)(4)(5)2 = 50 Joules.(The units of energy are Joules, as long as everything is measured in kilograms, meters, and seconds.)
1 cal=4 joule. 84 joules=84/4=21 cal
The sun produces 4 billion kilograms of energy per second..
