Robert is doing an experiment that calls for
the addition of 1 liter of water to a larger
vessel. robert has four different containers
to choose from. which one of the following
four containers would be the most accurate
and also the most practical way of doing
this?
a. a 2-liter container with a 2-liter mark on it
b. an empty 1-liter soda bottle without
volume marks on it
c. a 500-ml container with a 500 ml mark
d. a 5-ml graduated cylinder with 1 ml marks
on it hot boso bio

i think the answer is a and b

i wish you luck

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.
