Explanation:
Another name of covalent bonds is molecular bonds. Covalent compounds are formed by covalent bonds. The bonds in which atoms share one of more valance electrons are termed as covalent bonds. These types of bonds are in Liquid or gaseous State.
For example, methane is a covalent compound that is formed by the sharing of electrons between carbon and hydrogen atoms. Hence, Covalent compounds are usually described as the sharing of electrons between carbon atoms

Answer:
The gravitational acceleration is same for all objects.
a = b = c = d
Explanation:
Acceleration due to gravity or gravitational acceleration is the force exerted by Earth on unit mass of an object.
Acceleration due to gravity doesn't depend on the height of the object when the height is object is near to the surface of the Earth. Only when the height is comparable to the radius of the Earth, the value of gravitational acceleration changes.
But for the objects here, the gravitational acceleration is independent of the mass or height of the objects and has a constant value of 9.8 m/s².
Therefore, the gravitational acceleration of all the objects is same.
If 'a', 'b', 'c', and 'd' represent gravitational accelerations of objects 'a', 'b', 'c', and 'd' respectively, then a = b = c = d.
