(a) If the block reaches the bottom of the slope at 12.0 m/s, what is the average frictional force between the block and the surface of the slope? (b) What is the kinetic cofficient of friction of t
A transparent film (n = 1.26) is deposited on a glass plate (n = 1.52) to form a nonreflecting coating. The film has a thickness of 1.05 x 10-7 m. What is the longest possible wavelength (in vacuum)
How much work is done to bring this wheel from rest to a speed of 120 rpm in a time interval of 34.2 s?
A magnifying glass creates a virtual image of the observed object. Explain how it is possible, that humans can see the virtual images. The virtual image created by the magnifying glass is one exampl
In order to improve sharpness of pictures, photographers sometimes decrease lens's aperture (i.e. cover part of the lens). Explain why this procedure leads to a sharper image.
The observer is positioned so that the far edge of the bottom of the empty glass is just visible. When the glass is filled to the top with ethyl alcohol, the center of the bottom of the glass is jus
Two Lens that are L=29 cm apart are used to form an image. Lens 1 is converging and has a focal length f1=12 cm; Lens 2 is diverging and has a focal length f2=-7.0 cm. a) Determine the distance from
How many 65-W lightbulbs can be connected in parallel across a potential difference of 95V before the total current in the circuit exceeds 2.2A?
At what angle from the beam axis will the first order peak occur if the tube emits light with wavelength of 516.6 nm? At what angle will the second order peak occur?
A pirate sights a distant ship with a spyglass that gives an angular magnification of 24. If the focal length of the eyepiece is 14 , what is the focal length of the objective?
Suppose a small coil (808 turns, radius of 0.00847m and resistence 1.62 ohms) is placed at the center of the soleniod, it's axis paralell to the axis of the soleniod. Find the rms current induced in
At t = 0 s the leading edge of the loop hits the edge of the square region. Find the magnitude of the force you must apply to move the loop at constant speed:

What is the maximum current when the circuit is at resonance, if the amplitude of the (ac) voltage is 48.0 V
You apply an ac voltage that peaks at 60.0 V and observe, using an oscilloscope, that the resonance frequency occurs at 51900 s-1. What is the inductance of the inductor in millihenrys?
Include in your answer the distinction between positive and negative work and the influence of anthropometric factors.
To determine the maximum possible work that a heat engine could produce one must assume that there is:
A 50.0-kg block is being pushed up a 15.0° slope by a force of 300 N which is directed 30.0° below the slope. The coefficient of kinetic friction between the block and the slope is 0.200. Wh
