Answer:

Following are the solution to the given question:

Explanation:

  • Its interactions among light waves as well as different media were also called light products.
  • Even before sound rays hit a medium, the light rays bounce off.
  • Even at a similar angle with which the material initially struck its medium, sunlight reflecting.
  • When the light hits a mirror at such an angle of forty degrees, everything just rebonds at an angle of 40 degrees.
  • When light waves pass via a transparent medium, those who bend as well as change their direction.
  • Light is called transparent if it can pass via an object.
  • Whenever light waves strike a platform, this is neither re-elected nor refracted, nor expected to move.
  • The light of interacts with these materials are:

Reflection Mirror:

Water glass: refractive

Dark fabricate: Absorption 

  • Sound waves and waves of water are examples of matter waves.
  • Light waves and X-rays are electromagnetic waves.
  • There is no need for sound radiation to pass through a medium/requirement to communicate with other particles to travel like waves of matter.
  • No, even though sound waves didn't reach through the space vacuum.
  • Matter waves should interact with solid, liquid, or gas particulates to travel.

The light waves pass thru the air more quickly than sound waves.

Sound waves almost always go through a metal frame.

Light waves travel faster than electrical signals even though they don't have to crash in electromagnetic waves to particles.

What is 10 times as many as 1 hundred is blank hundred or blank thousand ?
Rama09 [41]

10 times as many as 1 hundred is 10 hundred or 1 thousand.

This is the question of simple multiplications related to a place value system.

The given equation in unit form can be rewritten as:

10 × 1 × 100 = (X × 100) or (Y × 1000)

Arranging in two parts, we get,

10 × 1 × 100 = X × 100           ........(1)

10 × 1 × 100 = Y × 1000         ........(2)

Now, calculating the value of X and Y,

From equation (1), we get,

10 × 1 × 100 = X×100

or, 1000 = X × 100

or, X = 10

Hence, 10 times as many as 1 hundred is 10 hundred.

Similarly, from equation (2). we get,

10 × 1 × 100 = Y × 1000

or, 1000 = Y × 1000

or, Y = 1

Hence, 10 times as many as 1 hundred is 1 thousand.

Therefore, 10 times as many as 1 hundred is 10 hundred or 1 thousand.

When 3.00 g of sulfur are combined with 3.00 g of oxygen, 6.00 g of sulfur dioxide (SO2) are formed. What mass of oxygen would b
bazaltina [42]
Actually, we can answer the problem even without the first statement. All we have to do is write the reaction for the production of sulfur trioxide.

2 S + 3 O₂ → 2 SO₃

The stoichiometric calculations is as follows:

6 g S * 1 mol/32.06 g S = 0.187 mol S
Moles O₂ needed = 0.187 mol S * 3 mol O₂/2 mol S = 0.2805 mol O₂
Since the molar mas of O₂ is 32 g/mol,
Mass of O₂ needed = 0.2805 mol O₂ * 32 g/mol = 8.976 g O₂

A burning splint will burn more vigorously in pure oxygen than in air because ________. a burning splint will burn more vigorous
GrogVix [38]
A burning splint will burn more vigorously in pure oxygen than in air because <span>oxygen is a reactant in combustion and concentration of oxygen is higher in pure oxygen than is in air.
Oxygen concentration in air is approximately 20%, the rest of are nitrogen, carbon dioxide and other gases. Oxygen is oxidazing reactant, that means oxygen give electrons in chemical reactions.
