Doppler Effect
Describing the classical Doppler Effect for sound waves. The Doppler Effect is a means through that wave properties (specifically frequencies) are influenced through the movement of a source or listener. If you've ever been waiting at a railroad crossing and listened to the train whistle, you've in all probability noticed that the pitch of the whistle changes as it moves associatively to your position. Same, the pitch of a siren change as it approaches and then passes you on the road.
A ball is 6.5 m from a convex mirror with a magnification of 0.75. If the image is 0.25 m in diameter. What is the diameter of the actual ball?
Unbalanced forces cause accelerations. In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down. To verify if the forces acting
the velocity of a particle moving along x axis is defined by v=kx^3-4x^2+6x where v is in m/s,x in m and k is a constant .if k=2 compute the acceleration when x=2m
