A farsighted man uses contact lenses with a refractive power of 2.00 diopters. Wearing the contacts, he is able to yead books held no closer than 25.0 cm from would like a his eyes. He prescription for eyeglasses to serve the same purpose. What is the correct prescription for the eyeglasses if the distance from the eyeglasses to his eyes is 200 cm 2.00 diopters

from a concave lens. The An object 5.3cm tall is 25.0 cm from resulting image is two-fifths is two-fifths as large the focal length of the lens? as the object. What is as cm

The drawing shows a rectangular block of glass (n=1.56) surrounded by liquid carbon disulfide (n=1.64). A ray of light is incident on the glass at point A with a O₁ = 47.0° angle of incidence. At what angle of refraction does the ray leave the glass at point B? A B

There is a magic item in Dungeons & Dragons called The Baton of Many Sizes, which is a staff that can magically change lengths between 0.305 m (1 foot) long and 15.2 m (50 feet) long, though it always has a mass of 3.18 kg.  Assume the moment of inertia of the staff is 112mL2112mL2  where L is the total length.  The angular acceleration is 4.9075 rad/s^2, the angular velocity is 17.57 rad/s. The staff then shrinks to a length of 1.12 m while no longer applying any torque.  What is the staff’s new angular velocity?

Samus Aran from the Metroid series of video games has the ability to roll into a ball to get into smaller areas. Samus rolls down a path which drops down 22.0 m. If she was at rest when she started at the top, what is her linear velocity at the bottom of the path? Treat her as a solid sphere with a moment of inertia of 2/5 mr^2 .

Moon Knight, from both comics and the show of the same name, has crescent shaped daggers he throws at enemies. To throw a crescent dagger he applies a force of 0.918 N at an angle of 75.0° relative to the dagger’s center of mass at a point 0.0690 m away from the dagger’s center of mass. If the crescent dagger has a moment of inertia of 2.57⋅10^−5 kg⋅m^2 , what is the angular acceleration of a crescent dagger as it is thrown?

Because you are taking physics, your friend asks you to explain the detection of gravity waves that was made by LIGO in early 2016. (See the section that discusses LIGO.) To do this, you first explain about Einstein's notion of large masses, like those of stars, causing a curvature of spacetime. (See the section on general relativity.) To demonstrate, you put a bowling ball on your bed, so that it sinks downward and creates a deep depression in the mattress. Your sheet has a checked pattern that provides a nice coordinate system, as shown in the figure below. This is an example of a large mass (the bowling ball) creating a curvature of a flat, two-dimensional surface (the mattress) into a third dimension. (Spacetime is four dimensional, so its curvature is not easily visualized.) Then, you are going to amaze your friend by projecting a marble horizontally along a section of the sheet surface that is curved downward by the bowling ball so that the marble follows a circular path, as…
