Answer:
Explanation:
The De Broglie's wavelength of an object is given by:
where
h is the Planck constant
m is the mass of the object
v is the speed of the object
In this problem, we have:
is the mass of the pellet
is the speed of the pellet
Substituting into the equation, we find the wavelength of the pellet:
Hi. The answer is, "gram". Hope this helps.
Take care,

Incomplete question as number of moles and length is missing.So I have assumed 3 moles and length of 0.300 m.So the complete question is here:
Three moles of an ideal gas are in a rigid cubical box with sides of length 0.300 m.What is the force that the gas exerts on each of the six sides of the box when the gas temperature is 20.0∘C?
Answer:
The Force act on each side is 2.43×10⁴N
Explanation:
Given data
n=3 mol
L=0.3 m
Temperature=20.0°C=293 K
To find
Force F
Solution
To get force act on each side it would employ by
F=P.A
Where P is pressure
A is Area
First we need to find pressure by applying ideal gas law
So
So The Force is given as:
The Force act on each side is 2.43×10⁴N
The wavelength of the wave that you are tuning in decreases.
Explanation:
The relation that relates with the speed of wave, frequency of wave and wavelength is given as
Wavelength =
The speed of the wave in a medium remains constant and therefore the wavelength is inversely proportional to the frequency of wave.
That is if the frequency is increased, the wavelength decreases and the wavelength is increased as the frequency is decreased.
Hence, as you tune your radio to a higher frequency, from 88.5 FM to 103,3 FM, the wavelength of the wave that you are tuning in decreases.
