02 Multiple Choice A disk is mounted horizontally on an axle and is free to rotate around that axle. A force is going to be applied in the same plane as
the disk to generate a torque on the disk. In order to get the highest angular acceleration possible, where and how should that force
be applied?
A. Halfway between the axle and the edge, perpendicular to the edge (toward the axis)
B. at the edge but not tangentially or perpendicularly
C. Halfway between the axle and the edge tangentially
at the edge perpendicular to the edge (toward the axis)
D. At the edge tangentially

Which is the best predictor of the radioactive nature of an isotope? o the proton-to-electron ratio the neutron-to-proton ratio o the neutron-to-electron ratio the electron-to-proton ratio

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

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
