What is the difference between `2.0 m` and `2.00 m`.

What is the difference in height between a point 270 m above sea level and 80 m below sea level ?

Two sinusoidal waves in a string are defined by the function y_(1)=(2.00 cm) sin (20.0x-32.0t) and y_(2)=(2.00 cm) sin (25.0x-40.0t) where y_(1), y_(2) and x are in centimetres and t is in seconds. (a). What is the phase difference between these two waves at the point x=5.00 cm at t=2.00 s ? (b) what is the positive x value closest to the original for which the two phase differ by +_ pi at t=2.00 s? (That os a location where the two waves add to zero.)

Two points are located at a distance of 10 m and 15 m from the source of oscillation. The period of oscillation is 0.05 s and the velocity of the wave is 300m//s . What is the phase difference between the oscillation of two points?
