Answer:
143975.31 N/m
Explanation:
Hook's law: Hook's law states that the force applied to an elastic material is directly proportional to its extension, provided that the elastic limit is not exceeded.
From Hook's law,
F = ke................... Equation 1
Where F = applied force, k = spring constant, e = extension/depression.
Make k the subject of the equation,
k = F/e ................. Equation 2
From the question,
The weight acting on the bathroom scale is the same as the applied force.
F = mg................ Equation 3
Substitute equation 3 into equation 2
k = mg/e ............. Equation 4
Given: m = 119 kg, e = 0.81 cm = 0.0081 m.
Constant: g = 9.8 m/s²
Substitute into equation 4
k = 119(9.8)/(0.0081)
k = 143975.31 N/m.
Hence the effective spring constant = 143975.31 N/m
Answer:
because energy is used to keep the things in place
Answer:
Control Variable
Explanation:
This is because time has to be the same for both materials throughout the experiment (an hour in this case).

Force is defined as the push or pull applied to the body. Its unit is Newton. The net force will be 10 N on the right side.
What is force?
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.
The given data in the problem is;
F₁ is forced by person 1 = 100 N
F₂ is forced by person 2= 90 N
Fₓ is the net force
Fₓ = F₁ -F₂
Fₓ = 100-90
Fₓ= 10 N
Hence the net force will be 10 N on the right side.
