On which factors liquid pressure depends |
|
Answer» according to me it depends upon the depth of the fluid ,the density of the fluid and also I think acceleration of gravity Pressure is the force acting perpendicularly on unit area of the object.Pressure depends upon the factors that follows:-(1)It depends on force applied.(2)Area over in which force acts.The same force can produce different pressure depending upon area in which it acts.When the force acts over a large area,the pressure produced is less.Pressure = Force/Area Height and density of liquid prominently... I think that liquid pressure depends on buoyant force |

What are difference between mass of an object and its weight |
|
Answer» ,Mass of an object is constant and does not change from place to place while weight of an object is the force with which it is attracted towards earth. Weight change from place to place. \t\xa0 Mass\xa0 Weight\xa0 Mass is the quantity of matter contained in the body.\xa0 Weight is the force of gravity acting on the body.\xa0 It is the measure of inertia of the body.\xa0 It is the measure of gravity.\xa0 Mass is a constant quantity.\xa0 Weight is not a constant quantity. It is different at different places.\xa0 It only has magnitude.\xa0 It has magnitude as well as direction.\xa0 Its SI unit is kilogram (kg).\xa0 Its SI unit is the same as the SI unit of force, i.e., Newton (N).\t |

How soil is formed explain |
|
Answer» first you need to know what is soil .it is the very fine particles of rock which is made up of weathing of rock in the formation of rock to stage take place :- 1) weathring 2) humification Soil is a mixture of rock particles, minerals, decayed organic material, air, and water. The formation of soil happens over a very long period of time and is majorly formed by the weathering of rock. Weathering in turn is the breaking down of huge pieces of rocks into smaller pieces by the action of natural forces, such as water, heat, glaciers, wind and roots of plants, etc. |

What is the drawback of Rutherford s model |
| Answer» The maine drawback of Rutherford\'s model was that it could not explain the stability of an atom. According to him -ve charged electrons are revolving around the +be charged nucleus. But according to Maxwell\'s theory of radiation whenever a charged body revolves it emits radiation and loses energy. Thus in that case the atom would collapse and matter would cease to exist | |

Difference between longitudinal and transverse waves |
|
Answer» \tLongitudinalTransverseThe movement of the medium is of the same direction of the waveThe movement of the medium is perpendicular to the direction of waveIt acts in one dimensionIt acts in two dimensionThe wave cannot be polarized or alignedThe wave can be polarized or alignedThis wave can be produced in any medium such as gas, liquid or solidThis wave can be produced in solid and liquid’s surfaceEarthquake P wave is an exampleEarthquake S wave is an exampleIt is made of refractions and compressionsIt is made of troughs and crests\t Well ...This is it ...as far as i think!.. When the particles of the medium move back and forth in the direction of motion of the wave then it is said to be a longitudnal wave And when the particles of the medium move up and down in the direvtion of motion of the wave then it is said to be a travsverse wave |
