Answer:
the seed of the sound in the air is 343.3 m/s
Explanation:
The computation of the speed of the sound in the air is shown below:
As we know that
Speed = Distance divided by Time
So, here speed be 515m
And, the time is 1.50 second
So, the speed of the sound is
= 515m divided by 1.50 seconds
= 343.3 m/s
hence, the speed of the sound in the air is 343.3 m/s

Answer:
the beetle's actual distance beneath the surface, d = 3.2 cm
Explanation:
The refractive index for the plastic is about 1.60
For overhead viewing, the expression for refractive index is
n = actual depth / apparent depth
Rearrange for actual depth
actual depth d = n x apparent depth
d = 1.60 x 2.0 cm
d = 3.2 cm
