General Physics 2 Namer PHYS1002-Pre Final Week PrimerfTake Home Exercise Set 1 Work in pencil Show all work Neatness Circle all answers in ink Include all units counts Part I Value- 10 Points 1. T or F:Voltage is a moasure of the potential eneny of a charge in an electric field. 2. The function of a capacitor is to J. If the plates of a capacitor are pulled apart without kosing any charge, the voltage on the plates will_ 4 TorF: The charges on capacitons connected in series are equal S. The resistance of a semiconductor (a) increases or (b) decreases with an increase in temperature. 6. Resistivity is an ) intrinsis or (b) estrinsis property of matorials 7 A voltmeter measures ()xoltagc. V: (b) diffirsnsss in yolags AV: or (c) slestron xoltscy Tor F:The radius of curvature and focal length of a thin lens are approximately identical values. For concave mirrors and convex lenses, incident parallel ays converge at the 10. Which of the following cannot form a real image when used by itself without other optics? b. convex mirror or a concave lens a, concave mirror or a convex lens c. convex mirror or a convex lens d. concave mirror or a concave lens 11. The wavelengths of visible light range fromnm 12. In above, the longest wavelength corresponds to the color 13. Give the order of the following in terms of increasing frrsuensy ( and the shortest to lowest frequency). ?gamma rays,-TV,?visible light,-xms,-infrared,-microwave 14. If the refractive index of water is 1.333, the spood of light in water is 15. Total internal reflection occurs only when a light ray travels from a medium of (a) high or () low refractive index into a m/s. medium of (c) higher or (d) lower refractive index. 16. A typical application for total internal reflection is 17. Tor F The speed and frequency of light is the same in any material. 18. The law of reflection states that 19. The variation of refractive index of a material with wavelength is called 20. Your enlarged image in a makeup mirror is (a) real or (b) virtual and is (e) srest or (d) invertedExplanation / Answer
True, V= potential energy/ charge.
------
Capacitor is used to store charge.
------
The volatge decreases,
V=E/d
Voltage is inversely proportional to distance between plates.
--------
True, in series both capacitors share same value of charge.
---------
Resistance of semiconductor decreases with increase in temperature.
-------
Comment in case any doubt.. Goodluck
