Breathing Process in Humans

                                         




                                          


We take in air through our nostrils. When we inhale air, it passes through our nostrils into the nasal cavity and is sent to the lungs through the wind pipe. The lungs are present in the chest cavity. This cavity is covered by the ribs in the both sides. A large muscular sheet called diaphragm forms the floor. During inhalation, ribs move up and and outwards the diaphragm moves down. This movement increases space in our chest cavity and air rushes into the lungs. The lungs get filled with air. During exhalation, ribs move down and inwards, while diaphragm moves up to its former position. This reduces the size of the chest cavity and air is pushed out of the lungs. This is the breathing process in humans.

Cyclone Formation

                                   




                                        


Before cloud formation water takes up heat from atmosphere to change into water vapor. When water
vapor changes back into liquid form as rain drops, this heat is released to the atmosphere warms the air around.The air tends to rise and causes a drop in pressure. More air rushes to the center of the storm. This cycle is repeated. The chain of events ends with the formation of a very low pressure system with very high speed winds revolving around it. It is this whether condition that we call a cyclone. Factors like wind speed, wind direction, temperature and humidity contribute to the development of cyclones.

Simple Pendulum

A simple pendulum consists of a small metallic ball suspended from a rigid stand by a thread. The metallic ball is called the bob of the pendulum. When the bob of the pendulum is released after taking it slightly to one side, it begins to move to and fro motion of a simple pendulums is an example of a periodic or an oscillation when its bob, starting from the mean position B, moves to A, to C and back to O. The pendulum also completes one
oscillation when its bob moves from one extreme position A to the other extreme position C and comes back to A. The time taken by the pendulum to complete one oscillation is called its
time period.

Fragmentation

Fragmentation is a type of asexual reproduction organisms like 

algae, star fish, and coral. The organism matures and gets broken up into two or more fragments or pieces. Which is developed into new individuals and live an independent life. After it mature the same process happens.

WORKING OF AN ELECTRIC BELL

                              

Electric bell consists of a coil of wire wound on an iron piece.The coil acts as an electromagnet.An iron strip with a hammer at one end is kept close to the electromagnet.There is a contact screw near

near the iron strip.When the iron strip is in contact with the screw,

the current flows through the coil which becomes an electromagnet.

It, then, pulls the iron strip.In this process, the hammer at the end of the strip strikes the gong of the bell to produce a sound.However,

when the electromagnet pulls the iron strip,it also breaks the circuit.

The current through the coil will stop flowing.It is no longer an electromagnet.It no longer attracts the iron strip.The iron strip comes back to its original position and touches the contact screw again. This completes the circuit.The current flows in the coil and the hammer strikes the gong again.This process is repeated in quick

succession.The hammer strikes the gong every time the circuit is completed.This is how an electric bell works.

SPORE FORMATION

Spore Formation is a type of asexual reproduction in organisms like

fungi.When spores are released they keep floating in the air.As they are very light they can cover long distances.Each spores is covered

by a hard protective coat to withstand unfavorable conditions,a spore germinates and develops into a new individuals.
