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)

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
