A 1-cm tall object is placed 10-cm in front of a concave mirror. a 4-cm tall image is formed infront of the mirror.
A) Draw a diagram for this problem.
B) Find the image location. Is it real or virtual?
C) Find radius of curvature of the concave mirror.
D) If the object is placed 40-cm in front of the mirror, find the location and the height of the image. Is it real or virtual?
The figure below shows a hollow cylinder that has a length equal to 1.80 m, a mass M equal to 0.88 kg, and radius equal to 0.20 m. The cylinder is free to rotate about a vertical axis that passes through its center and is perpendicular to the cylinde..
