Set up the simulator for Champaign, IL which has a latitude of 40° N. Complete the chart for the the rising and setting azimuths and cardinal directions for the Sun's daily path on the summer solstice (June 21), winter solstice (Dec 21), and the equinoxes

0.19 m/s and 0.45 m/s

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

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.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
