Jorin is building a model that shows how two different human body systems interact. He cuts a hole in a plastic tube, places a water filter in the hole, and connects a smaller tube directly to the filter. His model is shown below. Picture of a water filter

Jorin tests the model by running dirty water through the larger tube. Soon, the smaller tube begins to fill with clear water.

Which two body systems is Jorin most likely using his model to simulate?
A.
muscular and skeletal systems
B.
digestive and endocrine systems
C.
endocrine and nervous systems
D.
circulatory and urinary systems

explanation:

newton's third law, for every action there is an equal and opposite reaction.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
