The attraction between any two particle by virtue of their masses is referred as gravitational force. It is universal force.

1Thank You

Yogita Ingle 7 years, 1 month ago

The gravitational force is the force of mutual attraction between any two objects by virtue of their masses. It is a universal force. Every object experiences this force due to every other object in the universe. All objects on the earth, for example, experience the force of gravity due to the earth. In particular, gravity governs the motion of the moon and artificial satellites around the earth, motion of the earth and planets around the sun, and, of course, the motion of bodies falling to the earth. It plays a key role in the large-scale phenomena of the universe, such as formation and evolution of stars, galaxies and galactic clusters.

1 answers

Vicky Kumar 7 years, 1 month ago

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity cannot be added nor removed.

Why value of cp is greater than cv?

Posted by Ronak Burdak 7 years, 1 month ago

CBSE > Class 11 > Physics

1 answers

Ankit Aryan Shivan 7 years, 1 month ago

Cp is greater than Cv because at const.pressure whole heat is used in two ways. 1.Change in internal energy. 2.Work done,while at const. Volume,whole heat is converted into change in internal energy only. Hence Cp>Cv.

Why road looks straight ,as earth is round

Posted by Parneet Kaur 7 years, 1 month ago

CBSE > Class 11 > Physics

Ayush Mohite 7 years, 1 month ago

Because the road is only a unit square(or can say a very very small part or point on earth ) so since it is very small it seems to be straight. Like if you see a sphere and put your hand on it in which your thumb must be perpendicular to the rest of the hand you will see that the very small area taken as an observation it seems to be like almost same.

ANSWER

which is more elastic rubber or thin steel foil

Posted by Nakul Sagar 7 years, 1 month ago

CBSE > Class 11 > Physics

3 answers

Chesta Pawan Manchanda 7 years, 1 month ago

Because elasticity is equal to stress/strain and by this formula you can conclude that thin steel foil is more elastic. Let's do an experiment take a rubber and a steel foil and stretch them you will observe the stretching power of a rubber is higher but the longation of foil is higher than rubber.
