Which statements describe chemical changes? check all that apply. the after-rain smell is produced by an interaction between rain and the oils released by plants. a homemade volcano can be created by combining baking soda and vinegar. when it erupts, carbon dioxide gas is released. sheep are sheared for their wool. the wool is cleaned and twisted into yarn. the yarn is dyed and used to knit clothing. the statue of liberty has turned green over time due to the reaction of copper with carbon dioxide and water. mosaic art is created by smashing colored glass tiles and rearranging them to form a picture or design.

The answers are a,b and d

force tends to be low and long diustance masses are high

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.
