Answer:
<h2>16kg</h2>
Step-by-step explanation:
This problem is borers on elasticity of materials.
according to Hooke's law,<em> "provided the elastic limit of an elastic material is not exceeded the the extension e is directly proportional to the applied force."</em>
where F is the applied force in N
k is the spring constant N/m
e is the extension in meters
Given data
mass m= 24kg
extensnion=15cm in meters= =
we can solve for the spring constant k
we also know that the force F = mg
assuming
therefore
We can use this value of k to solve for the mass that will cause an extension of
Well on this problem recall area of a rectangle is defined by:
A = lw our w = 1/6 and our l = (x +
) we have let 'x' represent our original length.
12x + 8 = 11
12x = 11 - 8
12x = 3
x =
So our original length is
If arc =AB is equal to arcCD then line AB should equa lineCD
