4. Briefly describe how can you prove that weightof body is a kind of force. |
|
Answer» force is DEFINED as F=ma , where m = mass of a body & a= ACCELERATION of a body. And we also know that weight=mass*g, where g is GRAVITATIONAL acceleration. And this definition also FITS in the definition of force therefore it is safe to say that weight is a kind of force only. |

A chain of mass media is attached at two points Aand B of two fixed walls as shown in the figure. The tension between the chain is at A is.... please help me with itno spam!! |
|
Answer» As per QUESTIONS the vertical component of tension must BALANCE the weight of the chain. And also it is a case of variable tension since theta is changing. But still MAGNITUDES of horizontal component of tension at each point must be same at every point.Let's tension and point A and point B be T and at midpoint of chain be T'Then 2T SIN theta = mg which gives T = mg/2 cosecAAlso T cos theta= T'so, T' = mg/2 cot theta(NOTE : when you write you should use the symbol of theta instead of writing "theta")HOPE THIS HELPS YOU BETTER PLZ MARK ME AS BRAINLIEST |

Which of the following quantities cannot be exoressed in volts? potensialpotensial differenceemfwork done |
|
Answer» has the units of Force/Area = N/m 2 , while STRAIN (=Δl/l) is dimensionless. So option A is CORRECT.Surface tension is Force/Length, thus N/m, hence B is ALSO correct.Energy has the units of [ML 2 T −2 ], hence the units have to be KGM 2 /s 2 . Thus C is incorrect option.Pressure is Force/Area = N/m 2 , thus D is again correct. |

Meaning of viruswith full statement |
|
Answer» The earliest INDICATIONS of the biological nature of viruses came from studies in 1892 by the Russian scientist Dmitry I. Ivanovsky and in 1898 by the Dutch scientist Martinus W. Beijerinck. Beijerinck first surmised that the virus under study was a new kind of infectious agent, which he designated contagium vivum fluidum, meaning that it was a live, reproducing organism that differed from other organisms. Both of these investigators found that a disease of TOBACCO PLANTS could be transmitted by an agent, later called tobacco mosaic virus, passing through a minute filter that would not allow the passage of bacteria. This virus and those subsequently isolated would not grow on an artificial medium and were not visible under the light microscope. In independent studies in 1915 by the British investigator Frederick W. Twort and in 1917 by the French Canadian scientist Félix H. d’Hérelle, lesions in cultures of bacteria were discovered and ATTRIBUTED to an agent called bacteriophage (“eater of bacteria”), now known to be viruses that specifically INFECT bacteria. |
