Using Coulomb's Law calculate the electrical force when Q1 = -4.5 x 10^-8, Q2= -3.8 x 10^-9, and the separation distance is 1.5 m.

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.

The ph is the a.independent variable b.the dependent variable c.control group
