nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
To arrange these elements according to the atomic radius (smallest to largest) would be:
Be, Mg, Ca, Sr, Ba
Under normal conditions, water freezes at 0 degrees Celsius or 32 degrees Fahrenheit. However by, adding salt, the water will cause the freezing point to become lower.
oops pls forgive me I accidentally did the wrong question.
Answer:
is the de Broglie wavelength associated with a baseball that is moving with a velocity of 42 mph.
Explanation:
De-Broglie's wavelength, which is:
where,
= De-Broglie's wavelength = ?
h = Planck's constant =
m = mass of particle =
v = velocity of the particle
We have :
Mass of baseball = m = 220 g = 0.220 kg ( 1g = 0.001 kg)
Velocity of the base ball = v = 42mph =
1 m/s = 2.237 mph
De-Broglie wavelength of the baseball at v:
=1.604\times 10^{-34} m=1.604\times 10^{-25} nm[/tex]
is the de Broglie wavelength associated with a baseball that is moving with a velocity of 42 mph.
