What is 111111111*111111111 ?

To find it we use simple logic - Since 11*11=121, 111*111=12321 so we see a pattern here, the square of 11 give us three digits and reverses after 2 digits that is 121. Square of 111 gives us 5 digits and reverse after 3 digits that is 12321. Similarly square of 111111111 will be of 17 digits and will reverse after 9 digits that is 12345678987654321.

Suppose you are stuck in a car which is on a friction less surface and you have to move the car forward without coming out of the car, how will you do it?

Here we can can apply the law of conservation of momentum, since the surface is friction less so the net external horizontal force on the car is zero(Assuming no air drag). so the momentum of the system( Car and you) is conserved. so what you do is that you through something from inside the car(say=seat) towards the back of the car and the car will start moving forward. Lets see how- Lets say Mc=mass of car, Vc=velocity of car , Ms=mass of seat , Vs velocity of seat Now Mc*Vc=Ms*Vs (By Momentum conservation) so Vc= (Ms*Vs)/Mc So the car will start moving forward with a speed of Vc= (Ms*Vs)/Mc.
