The distance from the trough of one wave to the trough of another wave is wave amplitude

2 answers:

6 0

This is actually incorrect, the distance as stated above either from trough to trough or from crest to crest within a corresponding wave, would be referred or called as the wavelength of the given wave.

No, that would be the wavelength. It would also be equal to the distance from peak to peak. The amplitude is the distance from the midpoint to the peak or from the midpoint to the trough

What are some compare and contrasts between Terrestrial Planets and Gas Planets?

dexar [7]

<h3><u><em>The different types of planets would be the gas giants all have more than 12 moons whereas the terrestrial planets all have less than 3 moons. A second difference is that that gas giants are all larger in diameter than the terrestrial planets. Also the Gas Giants are usually bigger than Terrestrial Planets. Gas Giants also have thicker atmospheres, and have gaseous surfaces. Terrestrial planet tend to be smaller, and have solid surfaces. In our solar system, Mercury, Venus, Earth (home), and Mars are Terrestrial planets.I am glad to help anytime ...Brainliest?</em></u></h3>

The rate of effusion of an unknown gas was measured and found to be 11.9 mL/min. Under identical conditions, the rate of effusio

iren2701 [21]

Answer : The correct option is, (B) $CO_2$

Solution :

According to the Graham's law, the rate of effusion of gas is inversely proportional to the square root of the molar mass of gas.

$R\propto \sqrt{\frac{1}{M}}$

or,

$(\frac{R_1}{R_2})=\sqrt{\frac{M_2}{M_1}}$ ..........(1)

where,

$R_1$ = rate of effusion of unknown gas = $11.9\text{ mL }min^{-1}$

$R_2$ = rate of effusion of oxygen gas = $14.0\text{ mL }min^{-1}$

$M_1$ = molar mass of unknown gas = ?

$M_2$ = molar mass of oxygen gas = 32 g/mole

Now put all the given values in the above formula 1, we get:

$(\frac{11.9\text{ mL }min^{-1}}{14.0\text{ mL }min^{-1}})=\sqrt{\frac{32g/mole}{M_1}}$

$M_1=44.2g/mole$

The unknown gas could be carbon dioxide $(CO_2)$ that has approximately 44 g/mole of molar mass.

Thus, the unknown gas could be carbon dioxide $(CO_2)$

<h3>Answer:</h3>

d) 1 and 4

<h3>Explanation:</h3>

Elements are made up of particles known as atoms.
Atoms of the same element have the same properties as the element.
The atoms of an element may differ in terms of the number of neutrons and have a different mass number, such atoms are known as isotopes.
However, the isotopes have an equal number of protons or atomic number.
In this case, atom 1 has a mass number of 20 and an atomic number of 10 while atom 4 has a mass number of 21 and an atomic number of 21.
Therefore, atom 1 and 4 are isotopes of element E.
