Answer:

D.  Sound

Explanation:

<u>Waves</u>: one of the ways that energy may be transferred. Waves can be described as oscillations.

Electromagnetic (EM) waves are <u>transverse waves</u>.

EM waves can be separated into <u>seven groups</u> in the spectrum.  From long wavelength to short wavelength:

  • Radio waves
  • Microwaves
  • Infrared
  • Visible light
  • Ultraviolet
  • X-rays
  • Gamma rays

Sound waves are <u>longitudinal waves</u>.

The direction of oscillations is <em>different </em>between longitudinal and transverse waves:

  • <u>Longitudinal waves</u>: the vibrations are parallel to the direction of wave travel.
  • <u>Transverse waves</u>: the vibrations are at right angles to the direction of wave travel.

Answer:

Sound

Explanation:

EN waves are known as electromagnetic waves

  • They can be identified from the electromagnetic spectrum

They are divided into seven parts

  • Microwaves
  • Radiowaves
  • Visible light
  • X-rays
  • UV rays
  • Gamma rays
  • Infrared

We can only watch Visible light not others .

Sound is not transverse wave

What is 7.832 rounded to the nearest 10th?
Galina-37 [17]

When rounding you look at the number right after the one you want to round. The tenth place is the one right after the decimal. If the number after it is more than five it goes up by one, it it's less than five it stays the same. So since the number after the 8 is a 3 it stays the same.

The answer is 7.8

How far does light travel in the time it takes sound to travel 1 cm in air at 20°c?
kykrilka [37]
The speed of sound at 20^{\circ}C is approximately v=343 m/s. The distance covered by the sound wave is
s=1 cm=0.01 m
And the time it takes is
t= \frac{S}{v}= \frac{0.01 m}{343 m/s}=2.9 \cdot 10^{-5} s

Now we want to find how far the light travels during this time. Light travels at speed c=3 \cdot 10^8 m/s, therefore the distance it covers during this time is
S=ct = (3 \cdot 10^8 m/s)(2.9 \cdot 10^{-5} s)=8700 m

How independent are we on technology?​
Leona [35]

Technology makes us feel more alone because we are more dependent on social media connections than real life connections. Simply put, technology-independent architecture means not being biased towards any particular platform or software language.
