Answer:
Explanation:
Angular Momentum Formula For atoms=
Where:
m_{s}h is the momentum for one atom (m_s is the spin quantum number)
N is the number of atoms=
Where:
N_A is Avogadro Number
m is the mass of sphere
M is the molar mass of iron
Angular Momentum Formula For atoms will be=
Angular Momentum of Sphere=
where:
So,Angular Momentum of Sphere=
Angular Momentum of sphere=Angular Momentum of atoms
=
=
For iron, . So above equation will become:
Where R=2mm, M=0.0558Kg/mol (Molar Mass of iron),h=Planck's Constant/2π
Answer:
The speed of the water shoot out of the hole is 20 m/s.
(d) is correct option.
Explanation:
Given that,
Height = 20 m
We need to calculate the velocity
Using formula Bernoulli equation
Where,
v₁= initial velocity
v₂=final velocity
h₁=total height
h₂=height of the hole from the base
Put the value into the formula
Hence, The speed of the water shoot out of the hole is 20 m/s.
