Answer:
Rayon
Wool
Silk Yarn
Explanation:
Rayon
This is Fabric A. Rayon basically burns very quickly even quicker than fabrics like cotton and linen. Its ash is gray in color. The rayon fabric smells of burning paper when it is burnt.
Wool:
This is Fabric B. Wool is basically hard to ignite. It burns slowly. Its ash is dark in color. The wool fabric smells of burning hair when it is burnt.
Silk Yarn:
This is Fabric C. The silk yarn shrinks from the flame when it is burned. It has a grayish black ash. The silk yarn fabric smells burnt meat of when it is burnt.
1. Stop transmitting start and stop sending photons. This is typical morse code like transmissions of information. By varying the pattern of starts stops you vary the information sent. Also used in digital communications over radios, modems, and pulse dialing over radio/phones.
<span>2. Change the frequency. You use a pattern of shorter and longer wavelengths of radio waves higher and lower energies of individual photons to transmit information. This is frequency modulation </span>
Answer:
electric field amplitude is 0.1133 V/m
Explanation:
given data
energy density = 5.69 × 10^−14 J/m3
speed of light = 2.99792 × 10^8 m/s
permeability of free space = 4π × 10^−7 N/A2
to find out
corresponding electric field amplitude
solution
we know electric filed amplitude E is
E = BC ..............1
so first we find magnetic filed B from energy density
that is energy density
u = B²/ 2µ
so B = √2µu
put value
B = √2(4π×
×5.69 ×
)
B = 3.780645 × 
so from equation 1
E = 3.780645 ×
(2.99792 × 10^8)
E = 0.1133
electric field amplitude is 0.1133 V/m
