no I didn't. How can I do it using the c++?

it is c++ , can you help with the code ?

I am trying to generate a random number between i and j.

The code at the bottom always generates the same number which is 42.

How can I fix this ?

int RandInt (int i , int j)

{

return rand( ) % (j-i+1) + i ;

}

Lim x--> infinity (2x/x+1)^5

Can I get the limit into the brackets , apply l'hopital rule and the result ^5?

Then the answer is 2^5 ?

what is the limit of a^n as n reaches infinity if a <-1, and WHY ?

How to get the magnetic field in the centre of a squared wired of length L ?

studying for the final

Can u help with this problem?

A charged particle of mass 1.50 g is moving at a

speed of 1.50 3 104 m/s. Suddenly, a uniform magnetic

field of magnitude 0.150 mT in a direction perpendicular

to the particle's velocity is turned on and then turned off in

a time interval of 1.00 s. During this time interval, the magnitude

and direction of the velocity of the particle undergo a negligible change,

but the particle moves by a distance of 0.150 m in a direction perpendicular

r to the velocity. Find the charge on the particle.

I know that qvb=ma

The only unknown to get q is a. How to get it ?

Also I am confused, of how it is mentioned that change of velocity is negligible and there is acceleration ? shouldn't a be zero ?

Why is SF5 polar, while PF5 is non polar ?

What is the effect on a moving charge particle as the magnetic field become more intensified. The reason I am asking that I read in a book

that the magnetic field only have effect only on changing the direction of a moving charged particle and doesn't affect its speed.
