A ball falls off a table and reaches the ground in 1s. Assuming g = 10 m/s², calculate its speed on reaching the ground and the height of the table.
we can list the given data as, initial velocity , u = 0m/s time t = 1s g =…
Characteristics of Stationary Waves
The stationary wave have following characteristics ⇒ Stationary waves are…
A wave of frequency 500 Hz is travelling with a speed of 350 m/s. (a) What is the phase difference between two displacements at a certain point at times 1.0 ms apart? (b) what will be the smallest distance between two points which are 45º out of phase at an instant of time?
The given that can be listed is frequency n = 500Hz speed v = 350m/s we c…
