A conductor carries a current that is decreasing exponentially with time. the current is modeled as where is the current at time and is the time constant. how much charge flows through the conductor between and ?

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

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.
