We all know that acceleration is equal to The rate of net velocity V-U/t Now , A = V-U/t Or, V-U=At (cross multiply) Or, V=U+At Thankyou

Gaurav Seth 4 years, 6 months ago

(1) First equation of Motion:

V = u + at
soln.
Consider a body of mass “m” having initial velocity “u”.Let after time “t” its final velocity becomes “v” due to uniform acceleration “a”.

Now we know that:
Acceleration = change in velocity/Time taken

=> Acceleration = Final velocity-Initial velocity / time taken

=> a = v-u /t
=>at = v-u

or v = u + at
This is the first equation of motion.
—————————————-
(2) Second equation of motion:
s = ut + 1/2 at^2

sol.
Let the distance travelled by the body be “s”.
We know that
Distance = Average velocity X Time

Also, Average velocity = (u+v)/2

.: Distance (t) = (u+v)/2 X t …….eq.(1)

Again we know that:
v = u + at
substituting this value of “v” in eq.(2), we get

s = (u+u+at)/2 x t
=>s = (2u+at)/2 X t
=>s = (2ut+at^2)/2
=>s = 2ut/2 + at^2/2

or s = ut +1/2 at^2

This is the 2nd equation of motion.
……………………………………………………………
(3) Third equation of Motion
v^2 = u^2 +2as

sol.
We know that
V = u + at
=> v-u = at
or t = (v-u)/a ………..eq.(3)

Also we know that
Distance = average velocity X Time
.: s = [(v+u)/2] X [(v-u)/a]
=> s = (v^2 – u^2)/2a

=>2as = v^2 – u^2

or v^2 = u^2 + 2as

This is the third equation of motion.

Plasma is a state of matter that is often thought of as a subset of gases, but the two states behave very differently. But unlike ordinary gases, plasmas are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely.

Centrosomes are structures found inside of cells. They are made from two centrioles. Centrioles are microtubule rings. The main purpose of a centrosome is to organize microtubules and provide structure for the cell, as well as work to pull chromatids apart during cell division.

This law states that mass can neither be created nor destroyed in a chemical reaction.

Yogita Ingle 4 years, 6 months ago

The law states that mass can neither be created nor destroyed in a chemical reaction i.e. Total masses of reactants is equal to the sum of masses of products and the masses of unreacted reactants. For instance, the reaction of carbon with oxygen to produce carbon-dioxide involves conservation of mass in the following way.

C (12g) + O2 (32g) → CO2 (44g)

Here we used 12 g of carbon and 32 g of oxygen. After reaction the amount of carbon –dioxide produced will be 44g i.e. the sum total of the amount of  carbon and oxygen used.

32 electrons is the maximum number of electron thet can be accomodated in N shell.

Kushangi ..... 4 years, 6 months ago

According to the first rule : 2n^2 is the formula to find the max. No. of electrons So, 2*4^2=32 where n=the no. Of shell like (1,2,3......) Hence the max.electrons could be 32. Now according to octet rule it can carry only 8 as its max. No. Of electrons.
