Consider a 1.5 m optical telescope that has an angular resolution limit of 0.10 arcseconds when observing at a wavelength of 600 nm. How many times larger would a radio telescope need to be to have the same resolution when observing at a typical radio wavelength of 70 cm

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
