A person sitting in a rolling chair at rest throws a basketball forward. Since the person and the rolling chair have a greater mass than the basketball, how will the person and the rolling chair respond? They will have the same forward momentum as the basketball.
They will move backward at a lower speed than the basketball moves forward.
They will move backward at a higher speed than the basketball moves forward.
They will travel the same distance as the basketball travels but in the opposite direction.

answer; natural resources;

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
