What happens to the magnitude of the force of gravitation between two objects if: 1. distance between the objects is tripled? 2. mass of both objects doubled? 3. mass of both objects as well as the distance distance between them is doubled? ees class teacher grade 9 a oct 5 3 class comments

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
