1000 Joule = 1kJ\n109.47J * 1000 = 109470\nSo, yes...it is.

Gravitational Potential Energy = m*g*h joules\n        where   m - mass of the object in kg\n                     g - accelaration due to gravity in m/s^2\n                     h - height of the object from the reference in m\nHere the height from reference is 500m\ng is taken to be a constant and its value is 9.81m/s^2 though it may vary slightly with latitude, altitude and other such factors.\nMass is given as 0.400kg\nThus Potential energy = 0.400 * 9.81 * 500\n          Potential Energy = 1962 joules\n\nHope so u got wat u needed.

kilo is the prefix meaning 1,000, thus one kilowatt would equal one thousand watts.... if this is for a class you will probably run into some more numerical prefixes so ill give u a few more...\n\nassuming the standard unit is 1:\ncenti-100th\nmilli-1000th\nmicro-1,000,000th\nnano1,000,000,000th

i don't know how to calculate it, but i get 5250 Kj/mol from

First answer said convert Joules in electron volts and then compute. You don't need to convert to eV; just divide joules by potential difference (volts) to get 5 coulombs.

um.. this is a physics question, but i'll answer it~\n\nQ=cm(delta)t, therefore, Q=(4.184 J/g C)(75g)(60-35 C)\nQ= 10983 Joules

Formula:  J = K*m*(T2-T1)\n\nSince both K & m are 1 for your problem, J = 125 Joules\n\nK is the specific heat defined as 1 for water.  Varies with other materials.  Also this formula is not strictly true for 1 liter unless you assume the 1 liter weighs 1 kg.  Liters are volume and the formula is for mass.

They are both measures of energy. However, joule has mostly replaced calorie except for food where calorie is still the most common measurement. There are two main measurements of the calorie:\n\n* The small calorie or gram calorie is exactly equal to the energy needed to increase the temperature of 1 g of water from 14 °C to 15 °C. This is about 4.185 J. \n* The large calorie or kilogram calorie is exactly to the energy needed to increase the temperature of 1 kg of water from 14 °C to 15 °C. This is about 4.185 kJ, and exactly 1000 small calories. It is named after British scientist James Prescott Joule.\n\nThe joule is the SI unit for energy. The joule is a derived unit defined as the work done or energy required, to exert a force of one newton for a distance of one metre, so the same quantity may be referred to as a newton metre or newton-metre (also with meter spelling), with the symbol N·m or N m. It can also be written as kg·m2/s2. However, the newton metre is usually used as a measure of torque, not energy.\n\nAs a rough guide, 1 joule is the absolute minimum amount of energy required (on the surface of Earth) to lift a one kilogram object up by a height of 10 centimetres. To convert calories to joules, multiply by 4.1868.
