Suppose that, while in a squatting position, you stand on your hands, and then you pull up on your feet with a great deal of force. you are applying a large force to the bottoms of your feet, but no matter how strong you are, you will never be able to lift yourself off the ground. use your understanding of force and motion to explain why this is not possible.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
