Answer:

Explanation:
If we have a net force F acting on a body of mass m it will experiment an acceleration a. Newton's 2nd Law gives us the relation between these quantities: F=ma.
In our case, we want to calculate the acceleration, so we write:

With the values we have we get:

Weak winds that blow for short periods of time with a short fetch.
Answer:
circuit b will have the higher current than circuit a
Answer: 4 is the subscript in
.
Explanation:
We know that,
Subscript: The number of atom present in a given compound.
In
, 4 represents the number of chlorine atom in 1 mole of Silicon tetra chloride.
Coefficient: Number of atom which is used in reaction.
For example: In
, 3 is the coefficient of silicon tetra chloride.
A Product : In the balance equation, right hand side is called product.
A reactant : In the balance equation, left hand side is called reactant.
For example: the balance equation is

In this equation,
is the reactants and
is products.
Hence, 4 is the subscript in
.
