Three forces with magnitudes of 67 pounds, 109 pounds and 145 pounds act on an object at angles 170°, 250° and 320° respectivly with the positive xaxis Find the magnitude and direction

Which of the following correctly describes the early view of catastrophism?

By what primary heat transfer mechanism does the sun warm the earth?

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.
