Anyways the answer is x=2
3.92N
Explanation:
Given mass:
Mass of bag = 400g
The mass of a substance is the amount of matter it contains.
Weight of a substance is the vertical force acting on a body in the presence of gravity.
Weight = mass x gravity
Since the mass of the bag is 400g;
Now we convert to kg
1000g = 1kg
400g =
= 0.4kg
Weight of bag = 0.4kg x 9.8m/s²
Weight of bag = 3.92N
