Q1. A superhero ?ies 337m from the top of a tall building at an angle of 35? below the horizontal. What is the vertical component of the superhero's displacement?

Q2. Two long parallel wires each with a mass per unit length of 25.10 g/m are supported in a horizontal plane by 2.5 cm long strings. Each wire carries the same current, I, causing the wires to repel each other so that the angle between supporting strings is 20.46 degrees. Find the magnitude of each current. Answer in units of A.
