Homework H20.A Given: A disk having a weight of W and an outer radius of R rests on a rough, horizontal floor. A force F acts at the center of the disk and presses the disk against a wedge at surface B, with the wedge also being supported by a smooth wall at surface A. A vertical force P acts on the wedge. The coefficient of static friction at surfaces B and C is vs. The weight of the wedge can be considered to be negligible compared to the other forces acting on the system. Find: Determine the largest force P that can be applied to the wedge without moving the disk. What is the impending motion of the system at this value of the load: does the disk slip on the wedge or on the floor

What is the moment of inertia i of this assembly about the axis through which it is pivoted? express the moment of inertia in terms of mr

Substances that assume the shape of their container, but do not have a definite size are called

Intro: a solid ball of radius rb has a uniform charge density ρ. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.
