What is degree of freedom

Posted by Janvi Dahre 7 years, 2 months ago

Ayushi Ayushi 7 years, 2 months ago

Degree of freedom refers to the number of directions in which a system is free to move. A pendulum is free to move in only one direction, and hence, has 1 degree of freedom.

Ankit Aryan Shivan 7 years, 2 months ago

According to Bernoulli's principle,In case of steady flow(streamline fluid flow),non viscous, incopressible flowing in a tube having non-uniform cross-sectional area,sum of the pressure , K.E per unit volume and P.E per unit volume is constant.

I want its derivation!! Yaar

1Thank You

Yogita Ingle 7 years, 2 months ago

For a streamline fluid flow, the sum of the pressure (P), the kinetic energy per unit volume (ρv2/2) and the potential energy per unit volume (ρgh) remain constant.
Mathematically:- P+ ρv²/2 + ρgh = constant
- where P= pressure ,
- E./ Volume=1/2mv²/V = 1/2v²(m/V) = 1/2ρv²
- E./Volume = mgh/V = (m/V)gh = ρgh

What is the basis of caesium atomic clock

Posted by Ajay Ajay 7 years, 2 months ago

CBSE > Class 11 > Physics

Yogita Ingle 7 years, 2 months ago

To measure a time interval we need a clock. Clocks in India works on the atomic standard of time, which is based on the periodic vibrations produced in a Cesium atom. That’s why Indian clocks are also called Cesium Clock. The standard unit of time is second.

Why does the speed of a planet vary in it's orbit around the sun????

Posted by Sanidhya Jadaun? 7 years, 2 months ago

CBSE > Class 11 > Physics

Sarthak . 7 years, 2 months ago

Because the orbit is elliptical, the planet has to travel greater distance when it is near sun in comparison to when it is away from sun in the same time(second law)and hence its speed varies

Establish relation between two specific heat of gas which is Greater and why

Posted by Divy Patel 7 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Yuvraj Yadav 7 years, 2 months ago

Specific heat at constant pressure is Greater then specific heat at constant volume because at constant pressure there is a small change in volume which leads to work done and hence the total required energy increases while at constant volume there is no such change in volume and hence it is less than the other .

explain if the ice on the polar caps of the earth melts how will it affect the duration of the day

Posted by Divy Patel 7 years, 2 months ago

CBSE > Class 11 > Physics

1 answers

Prakhar Jadaun ? 7 years, 2 months ago

Days would get slightly longer . This is because the liquid water would distribute more evenly about the globe rather than all being near the poles, so the Earth's moment of inertia would increase. Since the Earth's angular momentum will not change, that means that its angular velocity (rate of turning) will decrease.

Sanidhya Jadaun? 7 years, 2 months ago

When ice on the polar caps will melt then whole water is spread throughout the earth due to this,moment of inertia will increase and by conservation of angular momentum angular velocity will decrease . Since angular velocity , w= 2π/t , therefore time period will increase,i.e.,duration of day will increase

2Thank You

Priya Dharshini ? 7 years, 2 months ago

Yes the days would be longer. Since the ice that was at the South Pole is now distributed around the world, there is a change in the distribution of mass. Like an ice skater opening their arms. Since the mass is further from the axis of rotation, the rotation slows; which means the days are longer.this due to increase in moment of inertia
