Question

Siobhan wants to measure the mass of a bag of flour. What should she do?

Answer 1

Hey there!
Awesome question=)

Siobhan can place it on a regular scale(0 gravity area), or she can use the "balance scale"

I hope this helps;)

Answer 2

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:

$m = \frac{F_{avg} }{g}$

where g: is the gravitational constant 9.81 m /s^2
