Nowadays, most people in the world love to listen to the music. Some of them use it for relaxation, some for inspiration and energy, but regardless of the reasons, music became an important part of our lives. This is proved by the fact that now we can meet more and more people with earphones in their ears while walking, going in subway or even working. Portable audio players are now as popular as the Beatles were in the 1960’s (Biersdorfer 2009).

Yogita Ingle 5 years ago

The medicines which kill or stop the growth of microorganisms in our body are called antibiotics. These are very useful to us as they prevent us from the effects of microorganisms. Antibiotics are made from bacteria and fungi. The penicillin is the first antibiotics which is discovered by Alexander Fleming in 1929. These days a number of antibiotics are used to cure various human and animal diseases. Streptomycin, Tetracycline, Erythromycin etc. are some common antibiotics. Precautions: We should take antibiotics only by the advice of a qualified doctor. Antibiotics should only be taken when needed. Otherwise, they may be harmful and become less effective in future.

It is also expensive like gold. Because of its black colour it is referred has black gold

Kartika Nandre 5 years ago

Because it is exhaustible resources. It needs a very long time to get prepared. We didn't get it easily.

Yogita Ingle 5 years ago

Petroleum is referred to as 'black gold' because when crude oil is extracted from the land it is black in colour. People call it gold because of its oils and value. It is very difficult to find.

This is because when crude oil is extracted from the land it is black in color.Crude oil is jet black before purification but after purification, it turns golden in color; therefore, it's tagged as Gold.

Virus lie between living and non living in air it is non living and in body of any organisms it will living
Viruses are microscopic disease causing entities which reproduce only inside the cells of the host organisms. Example = Chinken pox and Corona
virus is a non-living pathogen and it is acellular (meaning that it is a one celled organism) and extremely small. A virus cannot live on its own. This means that a virus needs to have a host in order to be able to survive and reproduce. Most viruses simply do not serve any useful purpose but not all viruses are harmful to humans.

When a box starts sliding, the contact point of irregularities do not get enough time to lock between the surface of the floor. That is why the static friction is more than sliding friction

Yogita Ingle 5 years ago

 The two sliding objects find less time to get interlocked against each other (objects and irregularities of surface). So they get less friction. Therefore sliding friction is always less than static friction.

Arshiya Bhatia 5 years ago

Static Friction is more than sliding friction because, in case of STATIC FRICTION, the body needs to overcome the inertia of rest. And also in case of SLIDING FRICTION, the body posses inertia of motion since the body is already in motion

Examples of Kharif Crops Following are some of the examples of Kharif crops: Rice Maize Sorghum Bajra Soybean Cotton Rabi Crops Rabi crops are known as winter crops.

No because aluminium is a reactive metal which can react with acid so if we store lemon pickle in it it will react with aluminium

Pragya Bharti 5 years ago

Thanks Kruthika,Manas and Bxngtan.....

Kruthika Reddy 5 years ago

No dear we cannot store lemon pickle in an aluminium utensil because aluminium is a metal and metals readily react with acids to produce hydrogen. When aluminium comes in contact with lemon, which is acidic , would react to give hydrogen and the pickles will be spoiled .
No,. Because aluminium utensil is metal and lemon pickle is is acidic so, when they come in to contact, chemical reaction take place in which hydrogen gas is produced and the lemon pickle is not useable any more.

Bxngtan ⁷ 5 years ago

No, we cannot store the lemon pickle in aluminium utensil because aluminium is a metal and lemon is acid. The acids react with aluminium to release hydrogen which would spoil the food and render it unfit for use.
