Yo sup??

we can solve this problem by applying Newton's 2nd law

F*t=Δp

p=momentum

pi=mu=1500*30

pf=mv=m*0=0

Therefore

F*3=1500*30

F=15000 N

Hope this helps.

Which of these solid compounds are most likely to have its dominant bonding mechanism as covalent? (Select all that are true.)
I am Lyosha [343]

The compounds that have covalent bonding as their dominant bonding scheme are diamond and silica.

A covalent bond is formed between two nonmetals. Usually, when two nonmetals combine, electrons are shared between the two atoms involved in the bond.

Now, the solids diamond and silica are predominantly covalent solids. The atoms that combine in diamond are carbon atoms(nonmetals) while the atoms that combine in silica are silicon and oxygen (nonmetals also)

Hence, diamond and silica both have covalent bonding as their dominant bonding scheme.
