The correct answer is: +5
Explanation:
An object is placed at 0; it means:
Initial position of the object = 0.
Now it moves to 3 units to right, so keeping the standard cartesian coordinate system in mind (in right right x-axis is positive and left x-axis is right), the new position of the object will be +3.
Object now moves 4 units to the left, it means +3 - 4 = -1; object is at the position -1.
Object then moves 6 units to the right, therefore,
Final position of the object = -1 + 6 = +5.
Displacement = Final position - Initial position
Displacement = +5 - 0 = +5

A parsec is a unit of distance used in astrophysics to measure the distance between celestial objects. It is equal to 3.26 light-years or approximately 31 trillion kilometers.
A parsec is a unit of distance used in astrophysics to measure the distance between celestial objects. It is equal to 3.26 light-years or approximately 31 trillion kilometers. The concept of a parsec is based on stellar parallax, which is a method used to calculate distances to nearby stars.

Globular clusters are nearly spherical groups of about 10,000 to 1 million stars. A typical galaxy may contain up to a few hundred globular clusters; our galaxy, the Milky Way, has somewhere between 125 and 200 globular clusters orbiting the galactic center.
