To choose the correct option: the light source which makes light my making a piece of metal hot enough to glow, among the options such as (A) fluorescent bulb (B) incandescent bulb (C) neon bulb (D) laser.

Answer to Problem 11STP
The correct option is (B).
Explanation of Solution
Introduction:
The light source which produces light by heating metal till it glows is incandescent bulb. Incandescent bulb or lamp is a source of light that works by incandescence that is emission of light produced by heating the filament. Incandescence means light produced by heating.
An incandescent bulb typically consists of a glass enclosure containing a tungsten filament. An
Conclusion:
Hence, the correct answer is (B).

(Figure 1) If it then falls freely (T = 0) from an essentially balanced at-rest position, determine the speed at which the corner A strikes the pad at B. The stone does not slip at its corner C as it falls. Suppose that height of the stone is L = 1.2 ft.

The battery has emf ε = 69 volts and negligible internal resistance. The inductance is L = 0.4 H and the resistances are R 1 = 12 Ω and R 2 = 9.0 Ω. Initially the switch S is open and no currents flow. Then the switch is closed. After leaving the switch closed for a very long time, it is opened again. Just after it is opened, what is the current in R 1?arrow_forward
- A capacitor with a capacitance of C = 5.95×10−5 F is charged by connecting it to a 12.5 −V battery. The capacitor is then disconnected from the battery and connected across an inductor with an inductance of L = 1.55 H . At the time 2.35×10−2 s after the connection to the inductor is made, what is the current in the inductor? At that time, how much electrical energy is stored in the inductor?arrow_forwardCan someone help me with this question. Thanks.arrow_forwardCan someone help me with this question.
