Which is more elastic???1 steel2 rubber band |
| Answer» Steel as it requires more stress to elogate than rubber....as youngs modulus= stress/strain...therefore more the numerator more the value of youngs modulus and more the youngs modulud nore is the elasticity<br>steel is more elastic than rubber because steel comes back to its original shape faster than rubber when the deforming forces are removed. Elasticity In Physics And In Common Life: In common life we label a substance as more elastic if it can be stretched more than others.<br>Steel<br>Steel is more elastic than rubber band because it\'s young\'s modulus is higher than rubber band<br>steel | |

Define gravitation potential at a point |
| Answer» Thanks<br>Gravitational Potential Energy\tPotential energy is due to the virtue of position of the object.\tGravitational Potential Energy is due to the potential energy of a body arising out of the force of gravity.\tConsider a particle which is at a point P above the surface of earth and when it falls on the surface of earth at position Q, the particle is changing its position because of force of gravity.\tThe change in potential energy from position P to Q is same as the work done by the gravity.\tIt depends on the height above the ground and mass of the body. | |
