Answer:
Atomic number of the daughter isotope = (Atomic number of the parent isotope) - 4
Explanation:
An alpha particle has atomic number of 2 and a mass number of 4
Losing two alpha particles would lead to a reduction of 4 in atomic number and 8 in mass number for the radioactive isotope, to give the stable daughter isotope.
The weight would be 62.92.
Answer:
The magnitude of force on P is 2.75 N
The magnitude of force on Q is 7.15 N
Solution:
As per the question:
Mass of the object, M = 11.0 kg
Acceleration of the object when the forces are directed leftwards, a = 
Acceleration when the forces are in opposite direction, a' = 
Now,
The net force on the object in first case is given by:
(1)
The net force on the object in second case is given by:
(2)
Adding both eqn (1) and (2):
Putting the above value in eqn (1):
Answer:
Let the volume of the cube be V and the fraction of cube outside water be f.
Thus, volume of ice inside water = volume of water displaced =(1−f)V
Under equilibrium,
Weight of ice = Weight of water displaced
⟹Vρ
ice
g=(1−f)Vρ
water
g
⟹(1−f)=

9
⟹f=

1
Thus, the percentage of volume outside water =10%
Answer:
Fission
Explanation:
When an atom splits into two parts, either through natural decay or when instigated within a lab, it releases energy. This process is known as fission.
