Concept explainers

A machine is a device that accepts energy in some available form and utilizes it to do a type of work. Energy, work, or power has to be transferred from one mechanical part to another to run a machine. While the transfer of energy between two machine par…

Kinetic Energy and Work-Energy Theorem

In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the d…

! Required information The radius of the Moon is 1.737 Mm and the distance between Earth and the Moon is 384.5 Mm. The intensity of the moonlight incident on her eye is 0.0220 W/m². What is the intensity incident on her retina if the diameter of her pupil is 6.54 mm and the diameter of her eye is 1.94 cm? W/m²

Required information An object is placed 20.0 cm from a converging lens with focal length 15.0 cm (see the figure, not drawn to scale). A concave mirror with focal length 10.0 cm is located 76.5 cm to the right of the lens. Light goes through the lens, reflects from the mirror, and passes through the lens again, forming a final image. Converging lens Object Concave mirror 15.0 cm -20.0 cm- 10.0 cm d cm d = 76.5. What is the location of the final image? cm to the left of the lens

! Required information A man requires reading glasses with +2.15-D refractive power to read a book held 40.0 cm away with a relaxed eye. Assume the glasses are 1.90 cm from his eyes. His uncorrected near point is 1.00 m. If one of the lenses is the one for distance vision, what should the refractive power of the other lens (for close-up vision) in his bifocals be to give him clear vision from 25.0 cm to infinity? 2.98 D
