What is the wavelength of 7.0-TeV protons? A) 550 nm B) 750 nm C) 5.4x10^-15 m D) 3.2x10^-18 m E) 1.8x10^-19 m
AnnZ [28]

Answer:

1.776 x 10^-19 m

Explanation:

Energy, E = 7 TeV

Let λ be the wavelength.

Energy = h c / λ

Where, h is the Planks,s constant and c be the velocity of light

h = 6.63 x 10-^-34 Js

c = 3 x 10^8 m/s

Convert TeV into J

1 TeV = 1.6 x 10^-7 J

So, E = 7 x 1.6 x 10^-7 = 11.2 x 10^-7 J

11.2 x 10^-7 = (6.63 x 10^-34 x 3 x 10^8) / λ

λ = 1.776 x 10^-19 m

An incandescent light bulb produces light when electrons flow through the
azamat
<span>Electric current passes through a filament of an incandescent bulb, thereby increasing it temperature. When current flows, it contains electrons through the filament to produce light. The answer is c. Typically, incandescent light bulb consists of a glass enclosure that contains tungsten filament. The glass enclosure contains either a vacuum or an inert gas that serves as the filament protection from evaporating. Incandescent light bulbs contain a stem attached at to its base to allow the electrical contacts to run through the envelope without gas or air leaks</span>
