A proton (mass m = 1.67 × 10-27 kg) is being accelerated along a straight line at 2.90 × 1013 m/s2 in a machine. If the proton has an initial speed of 2.00 × 105 m/s and travels 1.80 cm, what then is (a) its speed and (b) the increase in its kinetic energy?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

Which of the following is an example of motion in two dimensions?

An charge with mass m and charge q is emitted from the origin, (x, y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
