What difference between vector and scalar quantity |
|
Answer» SCALAR QUANTITY are those physical quantity which have only magnitude but not direction. The do not follow vector edition. Ex- area, length mass etc.Whereas VECTOR QUANTITY are those physical quantity which have both magnitude as well as direction. The follow the vector law. Ex- velocity, acceleration etc.(Vector edition is a way of additon and substraction in physics) Scaler quanity. Those quantity which have magnitude as well as direction Vector quantity. Those quantity which have magnitude only SCALAR QUANTITYboth magnitude and direction is dere.....VECTOR QUANTITYonly magnitude is dere not direction..... What is this ****?? |

What is uniform accelerated |
|
Answer» If the velocity of a body changes by equal amounts in equal interval of time however small or large these intervals may be the acceleration is said to be uniform . Acceleration due to gravity is an example of unifrom acceleration. if the velocity of an object increasing uniformly in equal interval of time then the body is in uniform accelerated motion. When a object move equal velocity in equal interval of time is called uniform Acceleration |

What is latent heat of boiling |
|
Answer» The latent heat of boling of a liquid is the quantity of heat in joules required to convert 1 kg of the liquid to vapour or gas, without changing in its temperature.For example- the latent heat of boling of water is. 22.5×10 to the power 5 joules/kg Hidden heat that helps it to break the bonds and then convert it into gas in known as latent heat of boiling. I am really sorry ?I try to remind it but i didn\' t know its answer? |

How does pressure help in liquidation of a gas |
| Answer» when you apply pressure for compressing you decrease the space available for the molecules and hence the collission frequency increases if we don’t change temperature.But when we lower the temperature we take the energy from molecules and thus due to low energy they come closer to each other without changing pressure of gas.When you apply external pressure on a gas the molecules of gas come closer to each other.thus the frequency of collision of molecules increases and the pressure of gas increases which opposes further increase in external pressure, and when this happens the volume of the gas decreases in this case temperature of gas remains contant if we compress it only via pressure. | |
