What\'s kinetic energy |
|
Answer» A moving partical is said to be have more energy then an identical partical st rest the energy of the moving partical Energy required for movement or *Energy* used for *Movement* is known as Kinetic Energy. Ex:- We take a container and keep some Marbles in it when we burn that container we see the movements of marbles.Now by this experiment we can say that the marbles have some Kinetic Energy. Energy required for movement or*Energy* used for *Movement* is known as Kinetic Energy.Ex:- We take a container and keep some Marbles in it when we burn that container we see the movements of marbles.Now by this experiment we can say that the marbles have some Kinetic Energy. |

Derive an expression for the excess pressure inside a soap bubble |
| Answer» Pnet = Pi - Pa Now, as the radius of the drop has increased, work has been done by the net internal pressure.So, this work done will be W = force x displacementorW = (pressure x area) x displacement and in this caseW = (pressure x area) x increase in drop radius so, the work done will beW = (P net x 4?r 2 ) x dr (1)but, the increase potential energy will be twicedU = 16?r.dr x S (2) this is because in case of a bubble there are two free surfaces, the outside surface and the inside surface. The potential energy will thus change accordingly. so, as (1) equals (2), we have(Pnet x 4?r2) x dr = 16?r.dr x Sor the net pressure inside a bubble will bePnet = 4S / r [twice than the that inside the drop] | |

What anamolous behaviour do water have? |
| Answer» Generally,matter expands on heating and contract on cooling.water also expands on heating if its temperature is greater than 4°C.However water contracts in the temperature range 0°C to4°C.The behaviour of water in the this temperature range is called anomalous behaviour of water. | |
