Answer:

Millions of years.

Explanation:

Fossil fuels are fuels formed by natural processes. It involves decomposition of dead and decaying animals, marine and plants for over million years. This some times take more than hundred million years to convert into fuel. This is why they are called non renewable resources of energy. The decomposition of dead plant species forms coal and decomposition animals of land and sea forms crude oil and gas.

Answer:

Conversion of carbon to fossil fuels takes hundreds of millions of years beneath the earth-crust.

Explanation:

  • Conversion of carbon to fossil fuels takes hundreds of millions of years beneath the earth-crust. Fossil fuel is formed by the anaerobic decomposition of dead remains of the plants and animals.
  • When the remains of the plants and animals get buried under the earth surface under high temperature and pressure it starts converting into fossil fuels. Coal, natural gas and petroleum are the extracts of the fossil fuel.

10. A book has a mass of 400 g. The surface of the book in contact with a table has dimensions 0.10m x 0.20 m. The gravitational
morpeh [17]

The pressure exerted on the table due to the book is 200 N/m².

The given parameters;

  • <em>mass of the book, m = 400 g = 0.4 kg</em>
  • <em>dimension of the table,  = 0.10m x 0.20 m.</em>
  • <em>gravitational field strength g =  10 N/kg.</em>

The area of the table is calculated as follows;

A = 0.1 x 0.2 = 0.02 m²

The pressure exerted on the table due to the book is calculated as follows;

P = \frac{F}{A}

where;

  • <em>F is the force of the book due to its weight</em>

<em />

P =\frac{F}{A} = \frac{mg}{A} = \frac{0.4 \times 10}{0.02} = 200 \ N/m^2

Thus, the pressure exerted on the table due to the book is 200 N/m².

In a circuit, the supplied voltage is 1.5 volts, and the resistor value is 3 ohms. What is the current in the circuit?
pogonyaev
Using Ohm's Law:

V = IR

Where V = Voltage in Volts, I = Current in Ampere, R = Resistance in Ohms

V = IR

1.5 = I * 3

1.5 = 3I

3*I = 1.5

I = 1.5/3

I = 0.50 A

Current in the Circuit is 0.50 Ampere.

SCORPION-xisa [38]

Answer:

4 : 1

Explanation:

<h3><u>Pulse rate</u></h3>

Also referred as heart rate can be affected due to vigorous exercise, age, health. Normally the pulse rate of an adult is between 60 to 100 beats per minute. pulse rate: 80 bpm.

<h3><u>Breathing rate</u></h3>

The amount of oxygen taken in inside of our body from the air. Breathing rate is usually affected due to age. Normal breathing rate of an adult is between 15 to 24 breaths per minute. breathing rate: 20 bpm.

<h3><u>Ratio of breathing to pulse rate</u></h3>

pulse rate : breathing rate

            80 : 20

              4 : 1
