The answer is True the mass is the matter of the object while the weight is the gravitational force on the object
Every force has an equal but opposite reaction, the forces are balanced out on the brick.
Weight (mg) acts downwards from the brick but the normal contact force from the table is acting upwards therefore resultant force is 0N equilibrium
You know the direction of the force is based upon the resultant force, so if you were to push the brick horizontally across the table it would travel horizontally

Answer:
The extension of the spring is 0.392 m.
Explanation:
Given;
spring constant, k = 50 N/m
mass attached to the spring, m = 2.0 kg
let the extension of the spring = x
The extension of the spring is calculated by applying Hook's law;
F = kx
mg = kx

Therefore, the extension of the spring is 0.392 m.
