The left end of a long glass rod 9.00 cm in diameter, with an index of refraction 1.55, is ground and polished to a convex hemispherical surface with a radius of 4.50 cm . an object in the form of an arrow 1.50 mm tall, at right angles to the axis of the rod, is located on the axis 23.0 cm to the left of the vertex of the convex surface.
part a: find the position of the image of the arrow formed by paraxial raysincident on the convex surface. part b: find the height of the image formed by paraxial rays incident onthe convex surface.

Isobars are lines of constant or equal pressure on a weather map. they can be used to find areas of low or high pressure over a broad area, and they can tell us how intense the system may be. on weather maps, you may have noticed areas that have a large l or h over a region with lines circling around them. the l stands for low pressure and h stands for high pressure. the lines circling them are isobars. check out the pressure system and isobars over georgia and florida. what is the present weather in this area ? a) clear and sunny b) cold and cloudy c) changing weather d) lots of precipitation
