According to newton's first law of motion, what happens to a marble traveling in a straight line on a flat hardwood floor that goes on forever?

question options:

the force applied by the floor to the marble will cause it to roll backward at the same speed it was moving forward.

a force applied by the hardwood floor will oppose the motion of the marble, causing the marble to slow to a stop.

gravity will cause the marble to stop after 6ft.

the marble will continue to roll along the hardwood floor at the same speed in the same direction 20 more seconds.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
