A metallic sphere has a charge of +4.0 nC. A negatively charged rod has a charge of -6.0 nC. When the rod touches the sphere, 8.2 x 109 electrons are transferred. What are the charges of the sphere and the rod now? [Sphere = 2.688 nC and Rod=-4.688 nC]

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud

True or false graphs must include scales that increase by the same amount

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
