Answer: 7.436 s
Explanation:
This situation is related to vertical motion, specifically free fall and can be modelled by the following equation:
Where:
is the final height of the object (when it makes splash)
is the initial height of the object
is the initial velocity of the object (it was dropped)
is the acceleration due gravity (directed downwards)
is the time since the objecct is dropped until it makes splash
Clearing :
Finally:
Answer:
The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity. ... Longitudinal waves, such as sound, are transmitted through media with velocities depending on the density and elasticity of the substance
