  1. d
    2.  
  2. b
  3. a
  4. c
  5. a. iv, b. iii, c. i, d. v, e. ii.
    1. force
    2. force
    3. motion
    4. weight
    5. pull
  7. Resultant force is also known as the net force. In many situations, more than one force acts on a body at the same time. All these forces collectively produce the same effect in the body as a single force hence it is defined as the single force which acts on a body to produce the additive effect of all the forces that work on that object. If two forces acting on an object are in same direction; they are added. If two forces are in different directions then we subtract them.
  8. Pressure = 35 N/7 m2
    = 5 N/ m2
