Answer: Essentially, no one is certain of the things that lie at the bottom of the sea. The oceans deepest darkest deep depths have proven more challenging to reach than traveling to the moon. In all of human history, 12 people have reached the moon, while only three have reached the bottom of the deepest part of the ocean: the Challenger Deep. The deepest point- located within the Marina Trench, reaches nearly 10,000 meters deep- beyond the depths which light can reach.

Answer:
Explanation:
Given that,
The volume of the balloon is
V = 440 × 10³ m³
Buoyant force F?
Given the density of the surrounding to be 2.58 kg/m³
ρ = 2.58 kg/m³
The buoyant force is the weight of water displaced and it is calculated using
F_b = ρVg
Where
F_b is buoyant force
ρ is density
V is the volume of the liquid displace.
g is the acceleration due to gravity
Then,
F_b = ρVg
F_b = 2.58 × 440 × 10³ × 9.81
F_b = 1.1 × 10^7 N
Answer:
0.04
Explanation:
Fraction of power converted to sound = 80% = 0.08
Fraction incident upon each eardrum onstage = 0.08/2 = 0.04
