1800 to 2400 calories
A person requires a minimum number of calories each day to provide energy for essential bodily functions such as breathing, circulation, and organ function. Calories are also necessary for activities of daily living and to maintain a healthy weight. Consuming enough calories ensures the body is supplied with the nutrients it needs to function properly.
In energy optimization, a local energy minimum is a point where the energy is lower than in its immediate surroundings, but not necessarily the lowest overall. A global energy minimum is the point with the lowest energy value in the entire system. It is important to find the global minimum to achieve the most efficient energy optimization.
photosynthesis requires cellular energy
A minimum energy transfer orbit is a hohmann transfer orbit. A hohmann transfer orbit requires the smallest amount of delta V as the first burn is at periapsis (closes point to body being orbited) and the second burn is at apoapsis. For a planetary transfer the minimum energy launch windows occur at intervals of the target planets synodic period in relation to the departure planet.
evaporation requires energy from the sun
EMV is the most healthy energy drink.
Electric energy requires the movement of electrons.
THRESHOLD ENERGY(T.E) You consider any particular reaction. the molecules of the reactants must necessarily possess certain minimum value of kinetic energy for the collision with other reactant and to from product . this minimum energy that the reactant molecules should possess is known as threshold energy (T.E) ACTIVATION ENERGY (A.E) Do you think all the molecules will possess this particular minimum kinetic energy required to form products? obviously not. if you take the graph of no of molecules vs their kinetic energy graph, you will see that only few molecules possess this minimum kinetic energy. so for other molecules also to participate in the reaction you need to provide certain extra energy to them by some means which is known as the activation energy. (A.E) Now the question arises ,how to calculate the activation energy. suppose in a reaction the average kinetic energy of the molecules of reactant be 10Joules , threshold energy is 50Joules. so what energy should be supplied for all the molecules to react. this is nothing but T.E - Average kinetic energy i.e.,50-10=40Joules. this is what is known as activation energy so ACTIVATION ENERGY (A.E) THRESHOLD ENERGY (T.E) AND AVERAGE KINETIC ENERGY (K.E) ARE RELATED AS A.E=T.E - K.E
A job that requires energy to do
The minimum kinetic energy that can be calculated according to the uncertainty principle is known as the zero-point energy.
A temperature change requires as gain or loss of heat energy.
Active transport requires energy to move a molecule.
