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

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
