Answer with Explanation:
It is given that
1) Force of Drag
2) Weight
Equating drag and weight we get
where,
'm' is mass of the object
'g' is acceleration due to gravity
'A' is the area of the person
is the density of air
Approximating the weight of a man to be 75 kg and area of man
Applying the values in the formula we get
Answer:
Explanation:
For moving particle , the wavelength is given by the expression
E is kinetic energy of the particle
Here particle is electron and its kinetic energy
E = 150 nm
= 1244 / 150
= 8.3 eV
8.3 X 1.6 X 10⁻¹⁹ J
=13.28 X 10⁻¹⁹ J
Putting these values in the expression for wavelength as given above we have
λ = .425 nm
Wave length of electron wave will be 0.425 nm
Hence its wavelength will be smaller and therefore magnitude of angle made by it will also be smaller. So magnitude of β will be smaller than that of α .
