Explanation:

This is the statement that best describes the difference between sound intensity and loudness. Loudness refers to a subjective perception of how loud or soft a sound seems to a particular listener. However, this loudness is in fact determined by the amount of energy in sound waves. This is known as sound intensity and is measured in decibels. Sound intensity is an objective measurement that can better help us determine how loud a sound is.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !
