An ion with a mass m and a magnitude of charge of 1e is initially at rest when it is accelerated by a potential difference of magnitude δv. after exiting the accelerating potential, it enters a region with a uniform magnetic field perpendicular to the ion's velocity. the ion moves in a semicircle of radius r. next, an ion with a mass m'and a magnitude of charge of 4e is accelerated by the same potential difference and deflected by the same magnetic field. the radius of its semicircular path is r' = 3r. find the ratio of the ion masses, m'/m.

m'/m = ?

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.

What occurs during a combustion reaction

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
