Answer:

Explanation:

Fuses and circuit breakers helps to:

protect equipment by stopping the flow of electric current; protect your house from fire

GFCI helps prevent electric shocks in a house:

GFCI outlets prevent electrocution if you are touching a wet appliance

Three 3ohms resistors in series would give you give a combined resistance of:

Resistance = (3+3+3)ohms = 9ohms

The piece of wood shown above has a mass of 20 grams. Calculate its volume and density. Then
kozerog [31]

We have that The Density and Volume is given as

\rho=0.67\\\\\V=30cm^3

The factors that affect Density are Mass and Volume

From the question we are told that

The piece of wood shown above has a mass of 20 grams.

Wood parameters

2cm

5cm

3cm

Generally the equation for the Volume  is mathematically given as

V=L*B*H\\\\\V=2*5*3\\\\V=30cm^3

Generally the equation for the Density is mathematically given as

\rho=\frac{m}{v}\\\\\\rho=\frac{20}{30}\\\\\rho=0.67

Therefore the factors that affect Density are Mass and Volume
