The radii of curvature of the surfaces of a thin converging meniscus lens are R1 = 12.0cmand R2 = 28.0cm . The index of refraction of the lens material is 1.60.
A) Compute the position and size of the image of an object in the form of an arrow 5.00mm tall, perpendicular to the lens axis and 45.0cm to the left of the lens.... This has two answers
B) A second converging lens with the same focal length is placed 3.15m to the right of the first. Find the position and size of the final image
C) Is the final image erect or inverted with respect to the original object?
A 68-kg person on skis is going down a hill sloped at 30° from the horizontal. The coefficient of friction between the skis and the snow is 0.11. What would be the magnitude of acceleration.
A classroom slide projector projects an enlarged (50 times taller) image of a 24mm high photographic film onto a screen located 10 meters from the projector. What focal length lens (cm) does the slide projector require to produce a sharply focus i..

A ball is thrown upward from the ground with an initial speed of 23.90 m/s; at = same instant, a ball is dropped from a building 16 m high. After how long will the balls be at the same height.
An indestructible bullet 1.85 cm long is fired straight through a board that is 11.10 cm thick. The bullet strikes board with a speed of 455m/s and emerges with a speed of 279m/s. (To simplify, suppose that the bullet accelerates only while the fr..
Then, a thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed the spheres still repel but with a force of F2 = 0.100 N. Using this information, find the initial charge on each sphere, q1 and ..
The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a maximum of 88.0 cm, what was the speed of bullet at impact with the block.
A 1000N force stretches a wire by 4.0mm . A:A second wire of the same material is twice as long and has twice the diameter. How much force is needed to stretch it by 1.0 mm? B:A third wire of the same material is twice as long as the first and has..
A woman is reported to have fallen 139 ft from a building, landing on a metal ventilator box, which she crushed to a depth of 30 in. She suffered only minor injuries.
