Q10M.3 Imagine that the proton and electron in a hydrogen atom were not charged. They could still form an atom based on the gravitational (instead of electrostatic) attraction between the two quantons. What would be (a) the minimum orbital radius and (b) the minimum energy of the electron in this gravitational atom? Answer E₁ = 4 x 10-⁹7 J.

Wolverine has an arm that is 1[m] long and claws that are 0.5[m] long. He's trying to knock over a wall. His shoulder can exert a torque of 1,500[N-m]. What is the ratio of force on the wall with vs without his claws extended? 1.5[m] point Pivot F /F Adamantium Wall without with claws claws A. 2/3 F Wolverine with В. 3/2 with claws С. 1 1.0[m] Pivot Adamantium D. I don't know but the torque direction is point Wall E. I don't know but the torque direction is Fwithout Wolverine Bare hands

Will rate!! A Freebody diagram is foreign object is shown in the figure. FA = 420 N, FB = 300 N, FC = 275N, and FD = 295N. Assume angle left = 31degrees, and alpha =13 degree. How much work in (J) does FA do on the object if it moves 2.9 m downward?
