Answer : The angular acceleration is 
Solution : Given,


The given angular velocity equation is,

At t = 0, 
At t = t, 
Angular acceleration : It is defined as the rate of change of angular velocity with respect to time.
Formula used for angular acceleration :

where,
= angular acceleration
= angular velocity at time 't'
= angular velocity at time '0'
t = time
Now put all the given values in this formula, we get the angular acceleration.


Therefore, the angular acceleration is 
B. New atoms are formed as products.
Answer:
(c) 
Explanation:
The solubility product of a solid is the amount of solid dissociates into its respective ions in the solution. Thus more the value of the Ksp, the more is the salt soluble in the solvent.
So, Given that:-




The salt having highest value of Ksp is AgCN. So, it is most soluble.
