The weighted average of the masses of the isotopes of an element

Physics
1 answer:
solmaris [256]3 years ago
4 0

Answer:

Atomic mass

Explanation:

The weighted average of the masses of the various isotopes of an element makes the atomic mass. This is why most atomic mass values usually have decimals.

In order to calculate the atomic mass of an element using the weighted average masses, we use the expression below:

                    Atomic mass = ∑m_{i}α_{i}

Where m_{i} is the mass of isotope i

           α_{i} is the abundance of isotope i

The abundance or geonormal abundance is the proportion by which each of the isotope occurs in nature.

At room temperature, sound travels at a speed of about 344 m/s in air. You see a distant flash of lightning and hear the thunder
bearhunter [10]

Answer:

<em>The lighten travels 0.853 miles.</em>

Explanation:

Sound: Sound is a form of wave which is conveyed through an elastic medium from a vibrating body to a listener.

v = 2x/t .......................................... Equation 1

making x the subject of the equation

x = vt/2........................................ Equation 2

Where v = velocity of sound in air, x = distance traveled by the sound, t = time

Given: v = 344 m/s t = 8 s

Substituting into equation 2

x = 344(8)/2

x = 1376 m.

x = 1376×0.00062 miles = 0.853 miles

<em>Thus the lighten travels 0.853 miles.</em>

Which of the following can be thought of as either a wave or a particle?
IrinaK [193]

Both matter and light have been demonstrated to exhibit wave-like and particle-like behavior.

Light as a wave: light can diffract & refract

Light as a particle: photoelectric effect, Compton scattering

Matter as a wave: Davisson-Germer experiment

Matter as a particle: find a picture of any kinematics problem in a high school physics textbook

Choice D

Explain diffraction at a single slit (light)
Leto [7]

Answer:

At some point on say, the receiving screen, light emanating from the left side of the slit will be out of phase (a difference of 1/2 wavelengths) from   light coming from the center of the slit.

Thus for every point that is left of the center of the slit, there will be a point on the right side of the slit that is out of phase,

There will be no light on the screen at that particular point and thus there will be a dark fringe there.

That is the basic explanation for the appearance of dark and bright fringes on the receiving screen.
