If mass of an atom is M moving with a speed v what will be it's speed ...
Given:
Mass of the atom = M
Speed of the atom = v
We need to find the speed of the atom after the emission of an alpha particle.
Solution:
When an alpha particle is emitted, the mass of the atom decreases by 4 units (since an alpha particle has a mass of 4 units) and the momentum is conserved.
Let's consider the initial momentum of the atom:
Initial momentum = Mass x Velocity = Mv
Since momentum is conserved, the final momentum of the system (atom + alpha particle) should be equal to the initial momentum.
Final momentum = Initial momentum
Let's consider the final velocity of the atom after the emission of the alpha particle as V.
Final momentum of the atom = Mass of the atom x Final velocity of the atom = M x V
Now, let's consider the momentum of the emitted alpha particle:
Mass of the alpha particle = 4 units
Speed of the alpha particle = 0 (given)
Momentum of the alpha particle = Mass of the alpha particle x Speed of the alpha particle = 4 x 0 = 0
Since momentum is conserved, the final momentum of the system (atom + alpha particle) should be equal to the initial momentum.
Final momentum = Initial momentum
Mv = M x V + 0
Mv = M x V
Dividing both sides by M:
v = V
Therefore, the speed of the atom after the emission of an alpha particle is equal to its initial speed, v.
Answer:
The speed of the atom after the emission of an alpha particle is v.
Mass of the atom = M
Speed of the atom = v
We need to find the speed of the atom after the emission of an alpha particle.
Solution:
When an alpha particle is emitted, the mass of the atom decreases by 4 units (since an alpha particle has a mass of 4 units) and the momentum is conserved.
Let's consider the initial momentum of the atom:
Initial momentum = Mass x Velocity = Mv
Since momentum is conserved, the final momentum of the system (atom + alpha particle) should be equal to the initial momentum.
Final momentum = Initial momentum
Let's consider the final velocity of the atom after the emission of the alpha particle as V.
Final momentum of the atom = Mass of the atom x Final velocity of the atom = M x V
Now, let's consider the momentum of the emitted alpha particle:
Mass of the alpha particle = 4 units
Speed of the alpha particle = 0 (given)
Momentum of the alpha particle = Mass of the alpha particle x Speed of the alpha particle = 4 x 0 = 0
Since momentum is conserved, the final momentum of the system (atom + alpha particle) should be equal to the initial momentum.
Final momentum = Initial momentum
Mv = M x V + 0
Mv = M x V
Dividing both sides by M:
v = V
Therefore, the speed of the atom after the emission of an alpha particle is equal to its initial speed, v.
Answer:
The speed of the atom after the emission of an alpha particle is v.
