We have the third equation of motion as,
v2 = U2 + 2aS
Where,
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} .........eqn1
From the first equation of motion we have {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 as
v2 = u2 + 2aS = third equation of motion.
Hence the third equation of motion is proved with the help of graphical method.

Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet.

When a object fall from height towards the earth under gravitational force

Shreeyanshi Shukla 5 years, 11 months ago

Did it helped you??

Shreeyanshi Shukla 5 years, 11 months ago

When a body is falling downwards or no force other than gravitational force is acting on it, it is a free fall.

No

Reena Pal 5 years, 11 months ago

No ,the value of acceleration due to gravity is more on poles and less on equator.... We took approx value 9.8m/s2 this difference due to radius of earth radius of earth is less as compare to equator as we know that g=Gme/d where G is gravitational constant and me is mass of earth and d is distance between the center of earth to the object d is less on pole hence g is more and d is more on equator hence g is less... Hole answer will help you....

Namrata Jindal 5 years, 11 months ago

No. Gravity varies inversely to square of distance. Since radius of earth is less at poles as compared to equator, acceleration due to gravity is stronger there.

At that time the heat provided to the ice to change its state is absorbed by the ice to change into liquid and so the temperature don't rise. It is the latent heat of fusion.

Because it is turning into ice so water is not so cool than that of ice

To understand all organisms easily and efficiently.

For better studies

Yogita Ingle 5 years, 11 months ago

It is necessary to classify organisms because:

  • Classification allows us to understand diversity better.
  • It helps in the identification of living organisms as well as in understanding the diversity of living organisms.
  • Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences.
  • It enables us to understand how complex organisms evolve from simpler organisms.
  • To understand and study the features, similarities and differences between different living organisms, they are grouped under different categories.
  • Classification is a tool which helps us to deal with a great diversity of living forms.
  • It is essential to understand the inter-relationships among the different groups of organisms.
  • Classification forms a base for the development of other biological sciences.

Object with mass 6 kg .

Vinit Kumar Dubey 5 years, 11 months ago
