Can the distance travelled by the particle be zero when the displacement is not zero?
The distance travelled by a particle cannot be zero when displacement is not zero because unlike distance which is a scalar, displacement is a vector quantity implying that it has both direction and magnitude.

Explain that can displacement be zero even if distance is not equal to zero?
If the distance is measured from a point other than the initial position of the object.
What is the formula used to calculate the velocity of an object?
The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.
When would displacement equal to zero?
When the object, whose location is being measured, is at the reference point for measuring displacement.
What describes the absolute value of the maximum displacement from a zero value during one period of oscillation?
The amplitude.
What is the distance that a number is from zero on a number line?
The distance from zero on a number line is called the absolute value.
