8.  acceleration =  = 1 unit .

9. acceleration =  = -1 unit.

10. acceleration =  = 0 units.

Explanation:

8. i) acceleration = velocity / time

  ii) In this figure velocity = time

  iii) therefore acceleration = = 1 unit .

9. i) acceleration = velocity / time

  ii) In this figure 4 = m + 5, therefore m = -1

     therefore velocity = (-0.5 time) + 5

  iii) therefore acceleration =  = -1 units.

10.) velocity is constant at 2

     therefore acceleration =  = 0 units

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
