Car 1 will roll down the ramp and exert a force on car 2. The force experienced by car 2 is measured indirectly using. If the force increases, car 2 will travel. The independent variable, or what’s being manipulated in the experiment, is. he dependent variable, or what’s responding, is . The height and starting position on the ramp are constants in this experiment. 1.the distance it travels or its speed
2.slower or farther
3.the starting height of car 1 or the type of bumper attached to car 2
4.the distance car 2 travels or the speed of car 1

Car 1 will roll down the ramp and exert a force on car 2. The force experienced by car 2 is measured indirectly using the distance it travels or its speed .

. If the force increases, car 2 will travel slower or farther  The independent variable, or what’s being manipulated in the experiment, is the starting height of car 1 or the type of bumper attached to car 2

he dependent variable, or what’s responding, is the distance car 2 travels or the speed of car 1

The height and starting position on the ramp are constants in this experiment.

Explanation:

hope this help

i know that you figure out the answer

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

the answer is b.) hydrogen bonds between bases.
