1 Its low gravitational influence.
2 Its extremely faint, compared to all the other objects out there.
3 Its Size
Condensation polymerization : releasing water as by product, occurs in monomer that has functional group that can react with each other e.g alcohol&carboxlic acid to form polyesters, carboxylic acid and amines to form polyamides,etc.
Radical Polymerization: occurs by propagating radical monomers or monomer that has unsaturated bonds, such as ethene, initiated by formation of radical from the monomer by using uv lights/other initiator, does not produce any by products
What are the elements so i can help?????
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
