Explain how could use a spring,a ruler,some standard masses and some graph paper to find the weight of an unknown object.Explain how could use a spring,a ruler,some standard masses and some graph paper to find the weight of an unknown object.
make a balance from the ruler, supported by a spring on one end. put the graph paper behind it. Now calibrate the balance with the standard masses, plotting the deflection as a function of mass. Then put the unknown object on it, and measure the deflection, compare its position on the graph with line you plotted with the standard masses.

Answer:
It is given below:
Explanation:
1: While measuring the mass from spring we can use Hooke's law. The spring will be stretched and this is how we can measure the weight.
2: In order to find weight from the standard mass, we simply have to multiply its mass with the 2.2Ibs.
3: By placing ruler at one end and object o the other, it will start tilting. We can use this formula f(x) = Rw(Rc - Sc) / (x - Sc) - Rw. Whereas Rw is ruler weight; Rc is ruler center of gravity, and Sc is sample center of gravity.
4:With the help of graph paper, we can find the weight like this. We have to draw the outline and measure the boxes by using the formula Smaller boxes = better area approximation
