State one advantage of fitting wide tyres on a vehicle that moves on earth roads.
1999 Q3 P1
State how the position of the centre of gravity of a body in stable equilibrium changes to that in the rest position when the body is slightly tilted and then released.

Fig. 2 shows a beaker placed on a bench. of ice is placed in the beaker as shown.
2002 Q2 P1
Fig. 2 represents a rock balanced at point O.G is the centre of gravity of the rock. Use this information to answer questions 5 and 6.
2002 Q3 P1
If the portion of the rock represented by the shaded part is chopped off explain why the rock may topple to the right.
2003 Q3 P1
Figure 3 shows two identical trolleys with loads A and B. The loads are identical in shape and size.
Given that the density of A is greater than that of B, explain why the trolley in figure 3(ii) is more suitable.
