<h2>
The seagull's approximate height above the ground at the time the clam was dropped is 4 m</h2>
Explanation:
We have equation of motion s = ut + 0.5 at²
Initial velocity, u = 0 m/s
Acceleration, a = 9.81 m/s²
Time, t = 3 s
Substituting
s = ut + 0.5 at²
s = 0 x 3 + 0.5 x 9.81 x 3²
s = 44.145 m
The seagull's approximate height above the ground at the time the clam was dropped is 4 m
Good i’m tired how about you
The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases. ( for amplitude)
Since sound at all frequencies has the same speed in air, a change in frequency means a change in wavelength. ( for frequency)
Bc they look the same from a farther distance
