Amar Kumar 8 years, 3 months ago

An erg is the amount of work done by a force of one dyne exerted for a distance of one centimetre. In the CGS base units, it is equal to one gram centimetre-squared per second-squared (g. cm²/s²). It is thus equal to 10⁻⁷ joules or 100 Nano joules (nJ) in SI units.

ANSWER

Does coefficient of friction depend on mass of the object?

Posted by Stuti Sharma 8 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Amar Kumar 8 years, 3 months ago

The magnitude of the friction force is the product of the mass of the object, the acceleration due to gravity, and the coefficient of friction. However, the coefficient of friction is not a function of mass or volume it depends only on the material.

Can water be made to boil without heating

Posted by Vishal Mishra 8 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Amar Kumar 8 years, 3 months ago

If the pressure is quickly reduced, the 221°F (105°C) water at normal pressure will now boil. For another example, put water at room temperature into a vacuum chamber and begin removing the air. Eventually, the boiling temperature will fall below the water temperature and boiling will begin without heating.

What is wave motion

Posted by Shubham Kumar 8 years, 3 months ago

CBSE > Class 11 > Physics

2 answers

Amar Kumar 8 years, 3 months ago

Wave motion:the motion of the particles of a medium in mechanically propagated waves (as water waves or sound waves)

A wave is an oscillation accompanied by a transfer of energy. Frequency refers to the addition of time.

Wave motion transfers energy from one point to another, which displace particles of the transmission medium–that is, with little or no associated mass transport. Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations.

Tushita Sangwan 8 years, 3 months ago

Wave motion, propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.

what do you mean by instanious velocity

Posted by Vishal Tiwary 8 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Amar Kumar 8 years, 3 months ago

Instantaneous velocity is defined as the rate of change of position for a time interval which is very small (almost zero). As this time interval approaches zero, the displacement also approaches zero. But the limit of the ratio of displacement and time is non zero and is called the instantaneous velocity.
