At lower speeds, the kinetic energy is 1/2 mv2 (1/2 times mass times speed squared), but since we are approaching the speed of light, the more accurate formula is (note: I am using root() to indicate the square root):
mc2(1 / root(1 - (v/c)2) - 1), which in this case is (mass in kilograms) x (300,000,000 m/s)2 x (1 / (root(1 - 1/4)) - 1) = mass x 9x1016 x (1 / (root(3/4)) - 1) = mass x 9x1016 x (1 / 0.866 - 1) = mass x 9x1016 x (1.155 - 1) = mass x 9x1016 x 0.155 = 1.395 x 1016 (Joule for every kilogram).
Note 1: This is the kinetic energy content of the spaceship, and the minimum amount of energy required to accelerate it to that speed; if any energy is wasted, the total needed would of course be more.
Note 2: The standard (non-relativistic) formula is 1/2 x mass times (150,000,000 m/s)2 = 1.125 x 1016. This is somewhat lower than if you use the correct relativistic formula. The more you approach the speed of light, the larger will be the discrepancy between the relativistic formula and the classic formula. At less than 1% of the speed of light or so, the discrepancy is so small that it isn't worthwhile to use the more accurate (and more complicated) relativistic formula.
If the activation energy elated to travelling is high, then a large amount of energy is required to start a chemical reaction. After the reaction is initiated, less energy is needed.
The coaster have a large amount of potential energy when it gain height, kinetic energy when it gain speed instead.
ATP contains a large amount of energy because it has high-energy phosphate bonds.
Leaves are broad and flat so that they can absorb large amounts of light energy from the sun, which is needed in order for photosynthesis (the conversion of carbon dioxide and water into glucose) to occur. The green colour signifies the fact that the plant contains chlorophyll, which is a pigment needed to trap light energy.
Because they are metabolically very active.They need a huge amound of energy for their activites.
The energy needed to cut down a tree depends on the size of the tree. Small trees need a less amount of energy than large trees.
Some sources of energy are described as dilute. This means that large amounts are needed to produce small amounts of useful energy.
because its to fat
yes
If the activation energy elated to travelling is high, then a large amount of energy is required to start a chemical reaction. After the reaction is initiated, less energy is needed.
Cardiac cells are very active. A lot of energy is needed
too much energy is needed to vaporize water
energy source is inconsistent
Enzymes are proteins that act as biological catalysts. Catalysts are substances that accelerate a chemical reaction. They decrease the activation energy of a chemical reaction.
saturated fats
Because the energy released by nuclear fission is extremely great compared with the energy released by coal burning.
The large calorie, kilogram calorie, dietary calorie or food calorie approximates the energy needed to increase the temperature of 1 kilogram of water by 1 °C.
