Answer:

They accelerate.

Explanation:

whether an object is ar rest or in motion, when external, unbalanced forces act on it, the object accelerates, as stated in Newton's second law:

F=ma

where F is the net force acting on the object, m is its mass, and a its acceleration. Therefore, if there are unbalanced forces acting on the object, the object will accelerate. This means that an object at rest will start moving (in the direction of the net force), while an object already in motion will increase (or decrease, depending on the direction of the force) its velocity.

What is the relationship between the mass of the objects and the force exerted?
pishuonlain [190]

Answer:

Objects with mass exert forces on each other via the force of gravity. This force is proportional to the mass of the two interacting objects, and is inversely proportional to the square of the distance between them. The factors G, M, and r are the same for all masses at the surface of the Earth.

The two-second rule applies to any speed __________ A. in all weather conditions. B. in ideal weather and road conditions. C. in
kumpel [21]

Answer:

The answer is A

Explanation:

A large risk of tailgating is the collision avoidance time being much less than the driver reaction time. Driving instructors advocate that drivers always use the "two-second rule" regardless of speed or the type of road. During adverse weather, downhill slopes, or hazardous conditions such as black ice, it is important to maintain an even greater distance.
