Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of +59. Sphere B carries a charge of
—9. Sphere
C carries no net charge. Spheres A and B are touched together and
then separated. Sphere C is then touched to sphere A and separated
from it. Last, sphere C is touched to sphere B and separated from it.
(a) How much charge ends up on sphere C? What is the total charge
on the three spheres (b) before they are allowed to touch each other
and (c) after they have touched?

What determines the amount of inertia an object has

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
