When studying quantum mechanics, the de Broglie wavelength is a key idea. De Broglie wavelength is the wavelength () that is connected to an item in relation to its momentum and mass.
Typically, a particle's force is inversely proportional to its de Broglie wavelength.
Assuming that the smallest measurable wavelength in an experiment is 0.830 fm , what is the maximum mass of an object traveling at 171 m⋅s−1 for which the de Broglie wavelength is observable?
We know:
- The shortest wavelength that is detectable, λm = 0.330 fm
- the object's velocity, v = 157 m/s
According to the following equation, an object's de-Broglie wavelength solely depends on its momentum:
λ = h/p = h/m*v, where,
- h = 6.626 × 10^(−34) J⋅s
- p = mv is the object's momentum. It is based on the moving object's mass, m, and velocity, v.
By rearranging the above equation, the object's mass can be written as:
m = h/λv
The maximum mass and the minimum de Broglie wavelength of the item are inversely correlated because the two quantities are inversely proportional to one another. When we enter the values provided, we get:
m = {6.626×10^(−34) J⋅s} / {0.330 fm × 157 m/s}
≈ 1.28×10^(−20) kg

Answer:
it gets euthanized. or it gets put down
Answer:
H---H and Cl---Cl bonds are broken and H---Cl bonds are formed.
Explanation:
The reaction between Hydrogen and Chlorine to produce HCl is:
⇒ ![HCl](https://tex.z-dn.net/?f=HCl)
In this reaction the reactants are
and
.
The product is HCl.
The bonds existing in the reactants are
1) H---H bond in
(Non polar and covalent bond)
2)Cl---Cl bond in
( Non polar and covalent bond)
The bonds existing in product is/are:
1)H---Cl bond in HCl (Polar and covalent bond)
So all the chemical bonds in the reactants are broken to produce the chemical bonds in the products
In other words,
The H---H bonds and Cl---Cl bonds are broken to produce H---Cl bonds.
Answer: In a chemical equation the reactants are located on the left side and the products are located on the right side.
Answer:
=2.7 g/cm³
=2700 kg/m³
Explanation:
Density is a ratio of the mass of an object to its volume.
The volume of the named block of aluminium is calculated as follows:
90mL - 75mL= 15mL
15mL = 15 cm³
The mass = 40.5 g
Therefore ρ=m/v
=40.5g/15cm³
=2.7 g/cm³
=2700 kg/m³
