Rajnish,
I thought marks are given to the first person, who gives correct answer. Anyway, 5 points to Sita di too.
Your answer regarding atomic mass and mass number is correct. So 5 points to you too.

I think you are right. this will be unfair to give marks to more than one person one same question so i will not count the points which has been given to member on question which already answered. 😊

@ sita di....ur ans. is right sita di....so 5 points to u......👏👏👏wase it was easy for u coz we both r the sawaries of the same kashti😆......wase i know how it feels when we don't  get selected in PMT😭 ....even i cudn't clear my 1 st attempt coz i was preparing for  12th board also.......wase even i'm more interested in MBBS...and not in BDS.......wase i was surprised to know that even u r a bio student....same pinch.....😆

 

@ rajnish bhaiya.......i'm not good at comp. but i think ur  ans. is....

Modem is short form of modulator-demodulator . It is an electronic device used in computers.IT'S USES - it converts a computer's digital signals into specific frequencies to travel over telephone or cable television lines. At the destination, the receiving modem demodulates the frequencies back into digital data. Computers use modems to communicate with one another over a network.

ok my question is what type of drugs r used in medicines  ?

you are right 5 points to you. If you want I can explain the funtioning of modem in detail😊.
I am not answering your question because i don't know the answer😭😭

next question-
What is difference between AM and FM??

AM stands for amplitude modulation and FM for frequency modulation.
With AM radio, the amplitude of signal (carrier wave) is varied to transmit various kinds of information about sound.

With FM radio, the frequency of signal is varied for the transmission.

Because of various disturbances, the signal loses some strength. In other words, its amplitude changes. This affects the quality of the signal being transmitted. So, this is a problem with AM.
FM does not suffer from this problem because accurate value of amplitude is not so important for FM.

Rajnish,

well answered avinash 5 points to you. avinash jasleen is bhopaliyellow. her name is jasleen and username bhopaliyellow. she answered two question one of transformer and other of modem so i gave her 10 points
your answer
_________________________________________________________
The force of friction by the table to the book is towards north.
Well i cannot draw the FBD here so let me explain. as we move table towards north due to inertia the book will try to remain in its position which means the relative motion of  book wrt table is towards south. so the force of friction acts towards north. this force of friction is reason why the book moves towards north together with table.

my question
what is the difference between hydrogen bomb and atom bomb?

 as three of you answered my question i am giving points to you all

hey tannishta i gave you marks 😛 full 5 points
