Students in science class were asked to do an experiment with a can of soda. They placed an unopened can of soda on a digital sc
ale and recorded the initial mass as 340 g. They then opened the soda can and left it open for a day. The following day, the students took the mass of the soda can again and noticed that it was only 332g. They then poured some of the soda into a glass and observed that it was no longer fizzy.

Answer:
Explanation:
Given
Initial reading on scale =40 N
So, we can conclude that weight of the sack is 40 N
After this a 10 N force is applied upward on the sack such that the net force becomes (40-10) N downward (because downward force is more)
This net downward force is the resultant of earth graviational pull and the applied upward force.
So, this downward force acts on the machine which inturn applies an upaward force of same magnitude called Normal reaction.
This situation can be diagramatically represented by figure given below
