when the dried-up seed pod of a scotch broom plant bursts open, it shoots out a seed with an initial veolcity of 2.62 m/s at an angle of 60.5 degrees above the horizontal. (A) How long does it take for the seed to land? (Assuming it gets shout out from ground level) (B) What horizontal distance does it cover during its flight?

Any color picture tube and electric field exerts a net force of magnitude 1.68x 10^-13 n on an electron the rest mass of an electron is 9.11 x 10^-13 what is the electron acceleration?

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
