You are applying a anti reflecting coating to your plane. You don't want to be seen by radar which uses 'light' of wavelength 2cm. determine the minimum thickness of this coating
Giancoli, page 30 --when they say that x-xo increases with the square of the initial speed. Why do they say square of initial speed only, what about square of final speed? And why do they ignore that the distance also decreases by a factor of 2.
A proton is initially at rest at a point where the potential is 459 V. Sometime later the proton is at a point where the potential is 218 V. If no force other than an electrostatic force acts on the proton, what is its final kinetic energy.
