Answer:
Newton meter,
Mass-spring system
Explanation:
Most commonly available Laboratory equipment is Newton meter.
It utilizes the spring system to subtend the hooked mass.
The dial indicates the amount of force required for the mass-spring system to be in equilibrium.
After performing the above described experiment. He should note down the atleast 5 sets readings given by the newton meter.
Average those 5 readings. The use the average answer to determine the mass as follows:
[tex]m = \frac{F_{avg} }{g}[/tex]
where g: is the gravitational constant 9.81 m /s^2
