While the cart is moving along an aisle, it comes in contact with a smear of margarine that had recently been dropped on the floor. suddenly the friction force is reduced for -40.0 newtons to -20.0 newtons. what is the net force on the cart if the "pushing force" remains at 40.0 newtons? does the grocery cart move at constant velocity over the spilled maragine?

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
