a cartesian diver is a classic science experiment which demonstrates the principle of buoyancy and the ideal gas law.
Answer: 6.125 ft
Explanation:
If this dish has the form of a concave upward parabola and its vertex 
is at the origin, its corresponding equation is:
Where:
is the radius, which can be found by dividing the diameter 
by half. Hence 
is the depth
is the vertex of the parabola, where its base is
Finding :
Finally:
This is where the the receiver should be placed
C. Observations and measurements
m = 5 kg
a = 2 m/s²
to find the force that accelerates the 4 kg object @ 2 m/s²
F = ma = 5 kg x 2 m/s² = 10 N
To find what acceleration 10 N would give a 20 kg object
a = F/m = 10 N/20 kg = 0.5 m/s
