In which direction does the sun appear to move across the sky? from west to east from east to west from north to south from south to north

In the southern hemisphere, the Sun (as well as the Moon and the stars) still rises in the East and sets in the West. This is because the "movement" of the Sun in the sky is caused by the Earth's rotation, and the northern and southern hemispheres are obviously rotating in the same direction ,,, so from east to west

Yes on edge the answer is B) from east to west.

it should be -8.6 cm hope this out

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.
