Answer:

Under 2,greater than

Explanation:

With both containers having the same size, gas pressure, temperature, the velocity of the gass will be determined basically by the characteristics of the gas. With the O2 molecules being much bigger than the H2 molecules, it would result in more hits between the molecules and the walls of the containers, resulting in a bigger average velocity for the O2 molecules.

So the answer is under 2, greater than.

What are the tiny particles that make up protons and neutrons
love history [14]


Protons and neutrons are made up of tiny particles called quarks.

A proton is a baryon made up two Up and one Down  quark.

A neutron is made of two Down quarks and one Up quark.

The Up quarks possess a 2/3 positive charge  while the Down quark possess a 1/3 negative  charge.

When we refer that a proton consists of two Up quarks and a Down, this simply means that its net appearance matches this description.

It is thought that quarks themselves are surrounded by gluons. 

Gluons are the basic particles underlying the strong interaction between protons and neutrons in the nucleus.

Determine the frequency of radiation whose wavelength is 7.67 x 10^-7 cm. Then, determine the amount of energy in the radiation.
dimulka [17.4K]

Answer:

They frequency = 3.9 * 10^16 Hz

The amount of energy E = 2.58 *10^-17 J

Explanation:

Step 1: Data given

wavelength is 7.67 * 10^-7 cm

Step 2: Calculate the frequency

f = c / λ

⇒ with  λ = the wavelength in nm = 7.67 nm

⇒ with c = the speed of light  = 3.00 * 10^8 m/s

⇒ f = the frequency = TO BE DETERMINED

f = (3.00 * 10^8 m/s) / 7.67 * 10^-9 m

f = 3.9 * 10 ^16 /s = 3.9 * 10^16 Hz

They frequency is 3.9 * 10^16 Hz

Step 3: Calculate the amount of energy

E  =  h *f

⇒ with E = the amount of energy (in joule)

⇒ h = Planck's constant =  6.626  *10^-34 J*s

⇒ with f = the frequency

E =  6.626  *10^-34 J*s * 3.9 * 10^16 Hz

E = 2.58 *10^-17 J
