Why do we need to classify organisms? |
|
Answer» To understand all organisms easily and efficiently. For better studies It is necessary to classify organisms because:\tClassification allows us to understand diversity better.\tIt helps in the identification of living organisms as well as in understanding the diversity of living organisms.\tClassification helps us to learn about different kinds of plants and animals, their features, similarities and differences.\tIt enables us to understand how complex organisms evolve from simpler organisms.\tTo understand and study the features, similarities and differences between different living organisms, they are grouped under different categories.\tClassification is a tool which helps us to deal with a great diversity of living forms.\tIt is essential to understand the inter-relationships among the different groups of organisms.\tClassification forms a base for the development of other biological sciences.\xa0 To make the study easy |

Derive three equation of motion by graphical metod |
| Answer» We have the third equation of motion as,v2 = U2 + 2aSWhere,v is the final velocity,S is said to be as displacement of the particle,u is the initial velocity,a = acceleration (constant),At t = 0 sec, u is the initial velocity of the particle.At t = t sec, v is the final velocity of the particle.Now, if we draw the graph for the above set of statements then, from the graph we have,(Displacement)S = Area of Rectangle + Area of Triangle{tex}S=\\frac{u t+1}{2(v-u)(t)}{/tex}\xa0.........eqn1From the first equation of motion we have\xa0{tex}t=\\frac {(v-u)}{a}{/tex}Now let us substitute the value of t in eqn 1{tex}S=u\\left(\\frac{v-u}{a}\\right)+\\frac{\\frac{1}{2}((v-u)(v-u))}{a}{/tex}By simplifying and rearranging the terms,We get the expression asv2 = u2 + 2aS = third equation of motion.Hence the third equation of motion is proved with the help of graphical method.\xa0 | |

First low of motikj |
|
Answer» According to forest law of motion when at rest it became be rest and when an object at motion it become in motion when an external force not applied Newton\'s First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion. |
