-- Each square meter of the bottom of the tank has 4 cubic meters
of water standing on it.
-- 4 cubic meters of water is equivalent to 4,000 liters.
-- So its mass is roughly 4,000 kilograms, and its weight is roughly
(4,000 x 9.81) = 39,240 newtons.
-- So the pressure on the bottom is roughly 39,240 newtons per
square meter, or 39,240 pascals, or <em>39.24 kPa</em>.

Answer:
807.88N/m
Explanation:
<em>The question has some missing details in it, nevertheless, based on the given data we want to find the spring constant K</em>
Step one
given data
Unstretched length = 33.5 cm
Final length of the spring = 42.0 cm
Δx= 42-33.5
Δx=8.5cm to m= 0.085m
mass m= 7kg
The force on the spring
F=mg
F= 7*9.81
F=68.67N
Step two:
From Hooke's law, we can make k subject of formula and find the spring constant k, we have
F=kΔx---------1
make k subject of the formula
k=F/Δx
k= 68.67/ 0.085
k=807.88N/m
