What is bulk modulus?write its SI unit |
| Answer» The bulk modulus of a substance is a measure of how incompressible/resistant to compressibility that substance is. It is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume.The inverse of the bulk modulus gives a substance\'s compressibility. | |

What is geostationary satellite ? State the necessary condition for a satellite to be geostationary |
| Answer» The sattelites which revolve around the earth along the equator are called geostationary sattelites. Their time period is same as that of the planet around which it revolves.The necessary condition for a sattelite to be geostationary is that -- the necessary centrifugal force must be provided by the gravitational force of the planet such that these two forces cancel out each other and the sattelite is suspended in the space. | |

Can we travle in time |
|
Answer» It is said that in earlier age the saints are able to travel in time because of meditation and concentration. And if our ancestors could do that we can also do that because we have those genes present in our DNA too but activating them is a very difficult task but it doesn\'t mean that this is impossible. So according to my view it can be done. Yes we can ,if we have that much strength in mind |
