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 planes’ acceleration from A to B is 500m/s^2
Explanation:
Given that the initial velocity u is 8000m/s
and also given the final velocity v=10,000 m/s
the time taken to move from A to B = 40 second
The acceleration is defined as the rate of change of velocity with time
we know that the expression for acceleration is given as
a=(v-u)/t
substituting our given data into the expression for a we have
a=(10000-8000)/40
a=2000/40
a=500m/s^2
The planes’ acceleration from A to B is 500m/s^2
Do u know Chinese ?if yes I can explain to u easily
We are given the gravitational potential energy and the height of the ball and is asked in the problem to determine the mass of the ball. the formula to be followed is PE = mgh where g is the gravitational acceleration equal to 9.81 m/s^2. substituting, 58.8 J = m*9.8 m/s^2 * 30 m; m = 0.2 kg.
