Please answer all and if not please answer a-c 5. For a charged disk with radius R and uniformsurface charge density ơ, the electric potentialat the center is given by V = oR/2ɛo. (Here wehave taken the potential to be zero at infinity.)b) What is the magnitude of the electric field ofthe annulus at this center point?c) What force acts on the gold nucleus when it islocated there?a) Given this, find the electric potential energy ofa gold nucleus (with charge +79e), if ithappens to be located at the center of acharged annulus as shown.d) The gold nucleus is given a tiny nudge out ofthe plane of the annulus. What will happen toit?e) Find the speed of the gold nucleus when itgets very far away from the annulus. (Denotethe mass of the nucleus by M.) *

Problem 1. A war airship leaves the port in Liberio and flies 175 km at 48.0" East of North and then changes direction to fly 235 km at 54.0 South of East. However because of the damage it took, it made an immediate emergency landing on a desert.

You are wondering how high that hawk is, surveying your back yard from a perch at the top of an oak tree toward the back property line. Remembering that you learned about vectors in physics, you measure off two components of a vector from your feet to the bird. Let "x" be parallel to the back of your house, and "y" perpendicular to the house out to the base of the tree. The vector to the bird would be (x, y, z). If x is 49 and y is 70 meters, what would z be in meters such that the angle from your feet to the bird is 45 degrees?
A Red Cross helicopter takes off from headquarters and flies 115 km in the direction 195° from North.It drops off some relief supplies, then flies 135 km at 350° from North to pick up three medics.If the helicoper then heads directly back to headquarters, find the distance and direction (rounded to one decimal place) it should fly. The direction should be in degrees from north.
