Scientists might model the water cycle by using a diagram. What are two benefits of this model? A. To show the direction of the cycle, arrows must be used.
B. It represents something that takes a long time to observe directly.
C. It is less dangerous than studying the water cycle directly.
D. It represents a complex process in a simpler way.

terd muffin is the correct answer

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

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.
