Explain in detail why you cannot hear in space but you can see light(explanation includes particle movement of liquid, solids, g

ases, and plasma)
Physics
1 answer:
expeople1 [14]3 years ago
4 0

Answer:

The reason why one cannot hear in space but light can be seen is because light and sound are different kinds of wave

Light is an electromagnetic wave that propagates by a changing magnetic field hat creates a changing electric field. Light is created by a vibrating electric charge, and is transmitted through a medium by the absorption and reemission of the light by the medium particles

Sound is a longitudinal mechanical wave that is propagated by the vibration of the particles of the medium.

Sound requires a medium to propagate and it cannot be propagated or heard through space which is a vacuum.

Sound is created by a source that is vibrating and the vibration is transmitted to particles in the medium including solids, liquids, gases and plasma that the vibrating energy is in direct contact with and the transfer of the sound energy continues between layers of adjacent particles for the medium for the sound to be propagated from place to place

What magnification is best for the observation of most tissue slides? Explain why this has proved to be true?
Komok [63]

Answer:

The 10X objective is use for the identification of actual size of histology tissues and 4X magnification is best for observation of most tissues slides

Explanation:

4X magnification is best for observation of most tissues slides because it has an objective lens that have lower power and have great high field overview which make it very easier to locate specimens on the slide. It is use to get the overview of histology slides. It is use to showcase more detailed observations about histology.

The 40X objective is use majorly to identify tissue , to observe the finer details and study tissue organization on the histology slide.

2. Below what depth would a submarine have to submerge so that it would not be swayed by surface waves with a wavelength of 24 m
Travka [436]

<u>Answer:</u> Below 12m of depth, the submarine has to submerge so that it would not be swayed by surface waves

<u>Explanation:</u>

To avoid the surface waves, a submarine has to submerge below the wave base. It is the position below which the motion of the waves is negligible.

This wave base is equal to half of the wavelength. The equation becomes:

Wave base = \frac{\text{Wavelength}}{2}

We are given:

Wavelength = 24 m

Putting values in above equation, we get:

Wave base = \frac{24m}{2}=12m

Hence, below 12m of depth, the submarine has to submerge so that it would not be swayed by surface waves

The theory of evolution is
tresset_1 [31]

one of several competing scientific models that all seem equally successful in explaining the nature of life on Earth

Explanation:

  • The theory of evolution is one of the several competing scientific models that all seems to successfully explain the nature of life on earth.
  • A theory is usually drawn from careful observation of scientific investigation.
  • Theories generally provides explanation into a phenomenon that occurs in nature.
  • They are products of careful scientific observations and experiments.
  • The theory of evolution is but one of them.

What is the average speed of a cheetah that runs 88 m in 5 seconds
vovangra [49]

So, the average speed of the Cheetah is 17.6 m/s.

<h3>Introduction</h3>

Hello ! I'm Deva from Brainly Indonesia. This time, I will help regarding the average speed. The average speed is obtained from finding the average of the speeds that occur or can be detected from the division between distance and travel time. The average speed can be formulated by :

\boxed{\sf{\bold{\overline{v} = \frac{s}{t}}}}

With the following condition :

  • \sf{\overline{v}} = average speed (m/s)
  • s = shift or distance objects from initial movement (m)
  • t = interval of the time (s)

<h3>Problem Solving</h3>

We know that :

  • s = shift = 88 m
  • t = interval of the time = 5 seconds

What was asked :

  • \sf{\overline{v}} = average speed = ... m/s

Step by step :

\sf{\overline{v} = \frac{s}{t}}

\sf{\overline{v} = \frac{88}{5}}

\boxed{\sf{\overline{v} = 17.6 \: m/s}}

So, the average speed of the Cheetah is 17.6 m/s.
