Nellie pulls on a 10kg wagon with a constant horizontal force of 30N. If there are no other horizontal gorces what is the wagons
kicyunya [14]

Answer:

a=3m/s^2

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:

a=\frac{F}{m}

With the values we have we get:

a=\frac{30N}{10Kg}=3m/s^2

What is the number “4” in SiCl4? a subscript a coefficient a product a reactant
Svetlanka [38]

Answer: 4 is the subscript in SiCl_{4}.

Explanation:

We know that,

Subscript: The number of atom present in a given compound.

In SiCl_{4}, 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 3SiCl_{4}, 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

2Mg+O_{2}\rightarrow 2MgO

In this equation, 2Mg+O_{2} is the reactants and 2MgO is products.

Hence, 4 is the subscript in SiCl_{4}.
