Recall and use the equation for mechanical working 1.7.2 Power Define power as work done per unit time and also as energy transferred per unit time; recall and use the equations 1.7.3 Energy State that energy may be stored as kinetic, gravitational potential, chemical, elastic (strain), nucl...
Bernoulli’s equation is a form of the conservation of energy principle. Note that the second and third terms are the kinetic and potential energy with m replaced by ρ. In fact, each term in the equation has units of energy per unit volume. We can prove this for the second term by su...

For the other two graphs, Equation (2) is similarly expanded. In applying the geometrical relation of Equation (2) to each of the above-considered three graphs and then expanding the geometric entities of each resultant equation in terms of the derivatives of the two-variable function as ...
Because the massmand speedvare given, the kinetic energy can be calculated from its definition as given in the equationKE=12mv2KE=12mv2. Solution The kinetic energy is given byKE=12mv2KE=12mv2. Entering known values gives KE = 0.5 (30.0 kg)(0.500 m/s)2, which yields ...
And then on the formula for a guide, get:, From the initial conditions: when,, knowable:,, L have,; (2) at that time, the equation was:, Can be written: [taking into account the higher mathematics, the general solution is:] Available: i.e.: And then on the formula for a guide...
Reactor antineutrinos are detected by the IBD interaction, as discussed above (Equation (1)), during which an electron flavour antineutrino is captured on a free proton (hydrogen nucleus), producing a positron and a neutron. The positron first deposits its kinetic energy and then it annihilates,...
