Weeding is done manually by using khurpi and by using mechanical machines. Weeds are also controlled by using some chemical substances like 2, 4-D. These chemicals are called weedicide and used to kill and destroy the weed.

Here, some of the most notable uses of electricity on a daily basis are mentioned.

  • Entertainment: Today, the modern sources of entertainment starting from listening to music from MP3 players, watching Television, playing movies in DVDs or VCDs or VCRs runs on electricity.
  • Healthcare: We can see the use of electricity for operating modern technologies every day. These surgical operations won’t even start without electricity. For example, the doctors need a powerful light during an operation on a patient and without electricity, the light won’t function, and operation can prove fatal.
  • Engineering: onstructions of buildings and structures for the convenience of people require electricity in every step. Building houses, installing gates and windows, welding of materials require current electricity to operate the machines.
  • Transport and Communication: Reaching places or communicating from a different corner of the world is only possible because of electricity. A power cut during airline travel can be dangerous.

Less than friction

Yogita Ingle 5 years ago

The most important function of the small intestine is the absorption of nutrients from food that passes through the tract. This large surface area allows for efficient uptake of nutrients. This efficiency is increased even more because each cell in the villi has microvilli on their surface. Hence the absence of this villis will decrease nutrient and digested food absorption by intestinal walls leading to severe nutritional disorders.

1) Friction comes into play when irregularities present in the surfaces of two objects in contact get interlocked with each other. In sliding, the time given for interlocking is very small. Hence, interlocking is not strong. Therefore, less force is required to overcome this interlocking. Because f this reason, sliding friction is less than static friction.

2) Along with several other brake system components, the brake pads are responsible for stopping a vehicle. They are made with special materials that maximize friction. When the brakes are applied, the brake pads grip the sides of the wheel that creates friction that slows and stops the bike.

Buddhism

Jainism

Rebirth is one of the principal beliefs in Buddhism. It is thought that the endless cycle of birth and re-birth can only be broken by attaining <i>Nirvana </i>(Enlightenment) Jainism believes that the circle of rebirths and deaths will continue due to good or bad deeds until liberation is achieved
Scriptures include <i>Tripitaka</i>, which is a vast text consisting of 3 sections: the Discipline, the Discourse and the Commentaries.  Jain religious texts are called <i>Agamas</i>
The principal teaching of Buddhism is that life is suffering and to escape suffering (end cause of desire) one needs to dispel ignorance by realizing the Four Noble Truths and practising the Eightfold Path Jainism lays emphasis on the respect of all living beings. Liberation from the cycle of rebirths is attained by taking the Five Vows and following the principles of the Three Jewels
Sin is not a concept in Buddhism Sin is defined as harm to others
Buddhism is divided into two major sects upon the death of Gautama Buddha. They are the Mahayana and the Theravada  Svetambara and Digambara are the two major sects of Jainism
According to some texts in Buddhism, there are beings in heaven but they are bound by “<i>samsara”</i>. They suffer less bu they ave, not yet achieved salvation Deities in Jainism are known as <i>“Titrtheneakas”. </i> But they are not worshipped in the conventional sense as they are regarded as wise teachers whose teachings must be followed

Common examples of internallubricants include fatty alcohols, esters (low esterification), and EVA wax. External lubricants provide metal release and help reduce process temperature. Common examples of external lubricants include PE waxes, paraffin, metal soaps, esters (high esterification), amides, and fatty acids.

Yogita Ingle 5 years ago

The eggs of birds such as hen and duck carry immature embryo in them. The hard shells of eggs protect them from damage. Once the fetus is matured, the egg hatches.  The trait of egg-laying animals is known as oviparity.

Sodium is stored in keresone bcoz, sodium in not to much hard ...that we can cut it by the khide also.... As souium is not too strong in texture but it is heighly reactive metal... When the sodium will come in contact with air, then the reaction between sodium and oxygen tools place and hydrogen gass is excreated.... So, sodium should not come concact with air ...so putted in keresone oil. ?If u r satisfied with my ans u can like it.. ?Thanks?
