Calculate the time (in years) it would take to send a message to the Galactic Capitol located at the center of our Milky Way galaxy and then receive the reply. We live about 2.5x10^20 meters away from the Galaxy center. Assume the message leaves the Earth and travels at the speed of light and that they take 1 year to decide what to answer..

If the area of a square has increased by a factor of 16, by how much has each side increased?

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.
