Answer:
The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.

The answer is C. Sesamoid bones
First solve the area of the ow the window os the submarine
A = pi* (0.15)^2= 0.0707 m2
The pressure it can with stand is
P= F/A = 1.2x10^6 N/ 0.0707 m2 = 16976527.26 Pa
Using the formala
P = pgh
Where p is the density of water
G is the accelartion due to gravity
H is the depth
H = P/pg
=16976527.26 Pa/ (1000 kg/m3)(9.81 m/s2)
H = 1730.53 m
The working equation for this problem is written below:
x = v₀t + 0.5at², where x is the distance traveled, v₀ is the initial velocity, a is the acceleration and t is the time
Let's apply the concept of calculus. The maximum speed is equated to the derivative of x with respect to t.
dx/dt = 8 ft/s = v₀ + at
Since the it starts from rest, v₀ = 0
8 = at
t = 8/a
The net acceleration is 0.7 - 0.35 = 0.35 ft/s². Thus,
t = 8/0.35 = 22.86 seconds
