A doubly ionized molecule (i. e., a molecule lacking two electrons) moving in a magnetic field experiences a magnetic force of 6.75 × 10 − 16 N 6.75×10−16 N as it moves at 207 m/s 207 m/s at 74.9 ∘ 74.9∘ to the direction of the field. Find the magnitude of the magnetic field.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

An inclined plane wrapped around a metal shaft is a a. lever b. screw c. pulley d. wedge

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
