A boater is accompanied by a person at least 16 years of age. In michigan, what is the youngest age that this person can be and
dexar [7]

The youngest age that this person can be and legally operate a boat powered by a motor of more than 35 hp will be 12 years of age.

<h3 /><h3>What is electric power?</h3>

It is the rate of the electric work done. Its unit is the watt. Horsepower is the unit of power.

A person under the age of 12 may only legally operate a boat with a motor that has more than 6 horsepower but no more than 35 horsepower

if they meet two requirements: they have a boating safety certificate, which they must have on board; and they are being closely watched by an adult who is at least 16 years old.

Hence the youngest age that this person can be and legally operate a boat powered by a motor of more than 35 hp will be 12 years of age.

Ex1. An atom has atomic number Z = 6 and mass number A = 12. Establish:
Maksim231197 [3]

Answer:

Ex1.

a) Carbon : atomic number Z = 6 and mass number A = 12

b) Protons = 6; electrons = 6 ; neutrons = 6.

Ex2.

Molar mass of H₂O₂ = 34 g;  BaF = 156 g; CO = 28 g.

Explanation:

Ex1.

a) the element with atomic number 6 and mass number 12 is carbon

b) number of protons and electrons in a element is given by its atomic number; and for neutrons its mass number - atomic number (A-Z).

⇒ protons = Z = 6;  electrons = Z = 6.;   neutrons = A-Z = 12-6 = 6.

Ex2.

Molecular formula of hydrogen peroxide is given by H₂O₂.

⇒ molar mass = 2×mass of hydrogen + 2×mass of oxygen

⇒ molar mass = 2×1 + 2×16 = 34.g

molar mass of BaF = mass of barium + mass of fluoride.

                               = 137 + 19 = 156 g

molar mass of CO = mass of carbon + mass of oxygen

                              = 12 + 16 = 28 g
