The Hubble space telescope has a resolution of40 milli-arc seconds (0.04 arc seconds).This means that the characteristic width of a pointsource is 40 milli-arc seconds, but we canfind the position of the source to a better accuracy(you know the position of the peak of aEgyption pyramid to a greater precision than the sizeof its base). Let’s say that Hubble canmeasure relative positions to an accuracy of 0.004arc seconds. What is the maximum distanceat which Hubble can detect stellar parallax, in unitsof parsecs? (2 pts)

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
