Due to a problem with its upper stage it failed to leave low Earth orbit, and reentered the atmosphere a few days later. 3x^2-2x+1=0 Rearrange the A pendulum of length l metres takes t seconds to complete one full oscillation. Mentor. I know hv is the energy supplied by the photon and the threshold energy is how much energy is required to eject an electron from the atom, so does that mean the (1/2)mv^2, which is kinetic energy, is just the amount of energy the electron has after its ejected from the atom? Also, if the energy of the photon isn't enough to eject an electron . well let me simplify how the equation was derived: you know that P=mv and Ek=1/2 m (v^2) Therefore, make v the subject in the momentum equation you will have v=P/m substitute this in to the kinetic energy equation for value of will now have Ek=1/2m (p/m)^2 if you solve that you get: Ek= 1/2m (p^2)/ (m^2) you can now .나연 밝기
