<u>Option-(D): </u>The compound is CO₂ and it has two atoms to form the covalent bonds with them, as there are two covalent bonds formed inside the compound which is then termed as the double covalent bond.
Explanation:
Most of the elements share the electrons among themselves in order to get stability and get the optimum level for producing the required compound, as for the CO₂ it shares its electronic configuration on two sides with two Oxygen molecules,O₂. CO₂ has a greater significance in the over all survival and presence of the living beings.
The velocity of the object does not change, it is a constant 54 km/hr. When velocity does not change, acceleration is zero. Using the formula Force = mass x acceleration, we find:
