An object spins in a horizontal circle with a radius of 15.0 cm. The rotations are timed and the amount of time it takes for it to go around once is 0.56 s. The centripetal force is measured to be 6.1 N. According to the experiment, the speed of the object is closest to:'

Which atomic model was proposed as a result of j. j. thomson’s work?

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
