Aproton with an initial speed of 400,000 m/s is brought to rest by an electric field. did the proton move into a region of higher potential or lower potential? a. because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential. b. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential. c. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential. d. because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
