Convex mirrors are often used in sideview mirrors on cars. Many such mirrorsdisplay the warning “Objects in mirror are closer than they appear.” Assume a convex mirror has a radius of curvature of magnitude 14 m and that there is a car that is 11 mbehind the mirror. For a flat mirror, the image distance would be 11 m and the magnification would be 1. Determine the position, orientation, and magnification of the final image.
A plane is flying in the horizontal plane. At time t1 = 0 s with the components of its velocity are vx= 100 m/s and vy = 120 m/s. At time t2= 20 s the components are vx = 80 m/s and vy = 142 m/s.
In a rectangular corrdinate system, a postitve point charge q = 6.00nC is placed at the point x = +.150 m, y = 0, and an identical point charge is placed at x = -.150 m, y = 0.
For the third circuit, consisting of a single battery and two light bulbs in parallel, What is the current through each bulb
