Answer:
The wave produced is a standing wave.
y' = [2ymax - kx] cos wt.
y max is maximum displacement, k is angular wave number, x is equal to the length L, w is angular frequency, t is time.
The time taken for the wave to travel to the ceiling and get reflected is given as:
t = 1/f = (2L)/nv. Where n =, 1,2,3, .... and v is wave speed, f is wave frequency.
Answer: Gravity
Explanation:The sun may have a lot of gravitational pull but the further away the less it has, meaning planets like uranus or neptune take a long time to orbit around the sun.
A theoretical perspective is a set of assumptions about reality that inform the questions we ask and the kinds of answers we arrive as a result.
