Explanation:
mass number is now 4 times less than the original value so alpha decay occur during alpha decay the mass number is decreased 4 times and atomic number decreased 2 times than the original value
Answer:
Explanation:
Given that,
Height of the inclined plane, h = 2.02 m
Final velocity of the object, v = 5.72 m/s
To find,
The moment of inertia of the object.
Solution,
As the object rolls down the inclined plane, its gravitational potential energy gets converted to the kinetic energy along with rotational kinetic energy.
Since,
On rearranging the above equation and finding the value of I as :
So, the moment of inertia of an object that rolls without slipping down is
