Plane A travels along the indicated path with a constant speed vA = 285 km /h. Relative to the pilot in plane B, which is fl ying at a constant speed vB = 350 km /h, what are the velocities which plane A appears to have when it is at positions C and E? Both planes are fl ying horizontally

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

think its the third option

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
