Q. The racing yacht America (USA) defeated the Aurora (England) in 1851 to win the 100 Guinea Cup. From the starting buoy the America's skipper sailed 400 meters at an angle 45° west of north, then 250 meters at an angle 30° east of north, and finally 350 meters at an angle 60° west of north. Draw the path of the America on a coordinate system as a set of vectors placed tip to tail. Then draw the total displacement vector.

Q. A galvanometer whose full scale current is 150.0 amps and coal resistance is 75.0 ohms is used with a 1.50 ohms shunt resistor to make an ammeter. what is the largest current which can be measured by the ammeter?
