Two objects are placed on a flat turntable at 10.0 cm and 20.0 cm from the center, respectively.
The coefficient of static friction with the turntable is 0.50. The turntable's rotational speed is gradually enhanced.
a. Which of the two objects will start to slide first? Why?
b. At what rotational speed does the inner object begin to slide?
An equiconvex lens has the radius of one curved surface is 0.12 m and focal length of 0.10 m. Determine the refractive index of the material of the convex lens.
Used normally, a 150-watt, 120 volt light bulb requires how many amps of current? Ans: Used generally, a 150-watt, 120 volt light bulb needs 1.25 amps.
Define the Magnets Magnets work according to rules similar to electric charges. All magnets have two poles, north (actually north-seeking) and south poles. Like poles repel and
Write down the relation between focal length and power of a lens. Write down the expression for the equivalent focal length of two thin lenses separated by a distance.
Inertia in an automobile You can view the same effect as in experiment 8 when you are riding in a car that is rapidly stopped. You have to brace yourself to keep from sliding
