Answer:
(A) The intermolecular attraction between HF molecules are stronger than between HCl molecules mainly to due hydrogen bonding.
Explanation:
Since Flourine is highly electronegative and as such, when it bonds with Hydrogen it forms a hydrogen bond. Whereas the HCL molecule is a polar molecule whose inter-molecular forces are dipole dipole interactions. Although a Hydrogen bond is a type of dipole dipole interaction it is stronger than the traditional dipole dipole forces and London dispersion forces. HF also has a shorter bond length which makes the bond and inter-molecular forces stronger as compared to HCL.
Explanation:
Newton's second law of motion states that the acceleration of an object is dependant on the amount of force applied and the mass of the object itself, which is illustrated by the equation
,
where 
is the force applied, 
is the mass of the object and 
is the acceleration.
Therefore,
Hence, 6000 N of force is applied by the engine to the car.
