9 A box at rest is accelerated by a rope attached with a motor as shown in the Fig 2.1. The velocity-time graph given below shows the pattern of its motion for 20 s. {a) If the box is pulled with constant unbalanced force 10N. Show that the initial acceleration of the box is 2,5 ms, and calculate its mass.
(b) After 2.0 second the box is being pulled by a constant force 12 N. Determine the size of frictional forces acting on the box at this time.
(c) Determine the distance of the box travels along the ground at 8.0s.

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.

Bohr’s atomic model differed from rutherford's because it explained that electrons exist in specified energy levels surrounding the nucleus. electrons are embedded within the rest of the atom like plum pudding. an atom is an indivisible sphere. electrons circle the nucleus.
