Glass is good insulator because of the following reason:

Thanks for joining brainly community!

Glass is considered a good insulator because of its special way its molecules are arranged and its properties.

Glass is not like other solid materials because it doesn't have a regular structure. This messy pattern of atoms in glass makes lots of tiny holes and dirt in the material. Air bubbles and dirt make it harder for heat to move through the glass, so less heat moves through it.

Glass doesn't transfer heat easily because it has low thermal conductivity. Glass does not allow heat to move through it easily and helps to keep heat inside.

Glass does not easily let electricity pass through it. This means that it doesn't let electricity pass through easily. Glass cannot conduct electricity because it does not have any free electrons or mobile charged particles.

Glass allows infrared radiation, which is a type of heat energy, to pass through it. Glass lets light in but stops some heat from getting through.

Answer:

They are all composed of gases.

Explanation:

The inner planets are mainly composed of types of rock. The surface and interior is rocky but the atmosphere is composed of gases. The outer planets happen to be composed mainly of gas, or in other terms, elements. The two primary elements that make up these planets are hydrogen and helium. Because the inner planets are made up of primarily, they have given the nickname the "Terrestial Planets" and the outer planets are called "Gas Giants" because of their gas (elements) composed atmospheres and overall interiors.

Answer:

1, 2, and 3.

Explanation:

Hypotheses must be able to be proven false, otherwise it’s a law. It must be consistent with other theories otherwise it’s not true, and it has to be possible to prove correct, otherwise it’s a theory.

The true statement is "Falsifiable by experimental testing or observations." The correct option is 1.

In science, a hypothesis is a proposed explanation or prediction for a phenomenon or set of observations.

A new hypothesis is a fresh idea put forth by a scientist to explain a phenomenon or observation that has not been explained or understood fully by existing scientific theories or hypotheses.

The new hypothesis should be based on previous knowledge and observations, and it should be testable and falsifiable through experiments or observations. Scientists use hypotheses to guide their research and develop theories, which are more comprehensive explanations backed up by multiple lines of evidence.

Therefore, only Option (1) is the correct answer.

The velocity of the resulting mass after the perfectly inelastic collision of identical balls of clay A and B is 1 m/s to the left.

The final velocity of the two identical balls is determined by applying the principle of conservation of linear momentum as shown below;

m₁u₁ + m₂u₂ = v(m₁ + m₂)

where;

m₁ = m₂ = m

let right direction = positive direction

let left direction = negative direction

m(4) + m(-6) = v(m + m)

4m - 6m = 2mv

-2m = 2mv

v = -2m/2m

v = - 1 m/s

Thus, the velocity of the resulting mass after the perfectly inelastic collision of identical balls of clay A and B is 1 m/s to the left.

The height of the liquid column is 4.08 metres.

The peak of the liquid column is 4.08 metres.

As we realize that any liquid exerts a strain at a factor relies upon on the density of the liquid and the vertical intensity. depth is given = h and the acceleration because of gravity is g.

calculation:-

pressure = ρgh

ρ = density of the liquid

g = accaleration due to gravity

h = depth from the surface

l = 500kg/m3

p = 20,000

g = 9.8 ms-2

20,000Pa= 500*9.8*h

h=4.08m

The stress is the measure of pressure acting on a unit region. Density is the measure of the way intently any given entity is packed, or it is the ratio of the mass of the entity to its extent. The relation between strain and density is direct. exchange in stress will be contemplated in a exchange in density and vice-versa.

Answer:

If a bar magnets neutral region is broken into two, the newly cut faces will become the new north or south poles of the smaller pieces.

Answer:

Explanation:

You will create two separate bar magnets. Let's say we have a bar magnet with a north pole at the top region, and a south pole in the bottom region. The magnetic field lines will run from the north pole to the south pole. If the bar magnet were broken into the two, the portion containing the north pole will now have a south pole at the point where it was broken. Similarly, the section containing the south pole will have a north pole at the point where it was broken.

The reason for this is because magnetic monopoles do not exist. There are electric monopoles, those are called electrons. But there are no magnetic monopoles. There is no such thing as a magnetic charge. Mathematically, this is captured in Maxwell's equations. The divergence of the magnetic field is always zero, which means there is no such thing as a magnetic monopole. There is nothing theoretically stopping a magnetic monopole from existing. A lot of theories actually favor it. We just have no proof of it, so we assume they dont exist.

A) The distance x from the nearest speaker when intensity is at maximum  ; 0.4272 m

B) The distance x from the nearest speaker when intensity is at minimum ; 0.8123 m

Given data :

Distance between speakers ( d ) = 0.695 m

Frequency of oscillator = 668 Hz

Speed of sound waves in air ( v ) = 343 m/s

Given that

λ = v / f

  = 343 / 668

  = 0.5135

Also

Δx = [tex]\sqrt{d^2+x^2} - x[/tex]

Δx = λ  for maximum intensity

λ  = [tex]\sqrt{d^2+x^2} - x[/tex]

x = ( d² - λ² ) / λ

  = ( 0.695² - 0.5135² ) / 0.5135

  = 0.4272 m

Given that

λ = v / f

  = 343 / 668

  = 0.5135

Also

Δx = S₁P - S₂P

Δx = [tex]\sqrt{d^2+x^2} - x[/tex]

since the intensity is minimum

Δx = λ/2

Therefore

λ/2  = [tex]\sqrt{d^2+x^2} - x[/tex]

x = ( d² - λ²/4 ) / λ

  = ( 0.695² - 0.5135² / 4 ) /  0.5135

  = ( 0.695² - 0.0659 ) / 0.5135

  = 0.4171 / 0.5135 = 0.8123 m
