A car is moving at a constant speed along a straight line. Which statement is true about the forces acting on the can Ο Α. The net force acting on the car from all directions is zero.
B. The net force acting on the car is greater than the car's weight.
C. The net force acting on the car is in the direction of the car's motion
OD. The net force acting on the car is in the opposite direction of the car's motion,

i think it's c. i'm not sure but i think so.

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.

ok whats the question if not i cannot you i need question and need a thing to answer
