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

Africa

Explanation:

Burning fossil fuels and deforestation is disturbingly heightened in Africa with almost no viable measure taking to control it's effect. No effective programs are presently in place to control excessive tree falling used for herbs, firewood, charcoal business and a whole lot. Below standard carbon rating PMS are in high circulation with fumes, carbon monoxide is full abundance in the atmosphere. Presently, all these unchecked activities have resulted into unexplainable excessive increase in temperatures, breeding neck twisting diseases, severe skin infections, dehydration and increase diabetes. Drought has eaten up landlocked cities in Nigeria and Central Africa. Infact farmers have lost count of the usual natural cycle of rainfall and the beginning of each farming season due to this essential evil of climate change

Talja [164]

Answer:

3,4

Explanation:

Hydrogen has no other electron hence there is no screening of the valence electron by inner electrons. It is the lightest known element with a relative molecular mass of 2. Screening effect refers to the fact that inner or core electrons prevent the outermost electron from feeling the attractive force of the nucleus.

user100 [1]
Let MM(x) be the molar mass of x.

MM(Pb) : MM(PbO)
=207.21 : 223.20  =  451.4 g : x g

cross multiply and solve for x
x=223.2/207.21*451.4
= 486.23 g

Percentage yield = 365.0/486.23= 0.75067 = 75.07% (rounded to 4 sign. fig.)

Anna007 [38]
Look out for angioedema (like hives but a deeper swelling due to an allergic reacrion), bleeding (such as intracranial, gastrointestinal and genitourinal hemorrhaging) and adverse reactions to drugs. Nausea, blood pressure spikes, severe headaches, acute hypertsnsion, etc are other signs of negative reacrions to iv t-pa as well.
