Coulomb interaction is responsible
Answer:
April to June
Explanation:
Not really an explanation, I just know it.
Answer:
thermoset
Explanation:
A thermoset material is a polymer that is irreversibly hardened by curing. Curing is induced by heat and cannot be undone because the polymers cross link during the process, creating permanent chemical bonds.
Answer:
F = 0.483 N
Explanation:
Initial momentum, 
Final momentum, 
Time, t = 31 s
We need to find the force of a lead ball. We can use here the impulse momentum theorem.

F is force

So, the force is 0.483 N.
