Let us assume a remote controlled car which operates at 2.4GHz frequency band. When the accelerate or left or right turn button is pressed what value changes so that the car detects which button was pressed?

Everything is in '+' ... terms can cancel out only if there is some '-' if I'm right

(1+x+x2+x3+x4+x5+x6+x7+x8)(1+x2+x4+x6+x8)(1+x3+x6)(1+x4+x8)(1+x5)(1+x6)(1+x7)(1+x8) = 1+x+2x2+3x3+5x4+7x5+11x6+15x7+22x8+...+x56 Please explain me the step-wise procedure to arrive at the solution.

sand bag is dropped...i can understand that vertical acceleration is 9.8m/s^2...so vertical velocity increases in a.p (9.8, 19.6... m/s)...but this book says horizontal velocity of sandbag is constant and same as that of hot-air balloon (i.e., 12m/s)...I think the horizontal velocity should...

In a thermo flask the air between the outer and under wall is sucked out and a vacuum is created. So the air pressure should push the outer wall towards the inner wall and vice versa. But it doesn't happen. Why?

Ok thanks

How can you say that displacement is area under the velocity curve?

acceleration= velocity/time

Yup

v=d/t ;d=vt a=d/t^2 ;d=at^2 1/2d+1/2d=1/2vt+1/2at^2 d=1/2(vt+at^2)

d=vt+1/2at^2 Derive me this formula please... When I do I get 1/2(vt+at^2)...i know that I'm doing a mistake by not considering the initial velocity... So how do I correct it?
