Q-3: n vehicles occupy squares (1, 1) through (n, 1) (i. e., the bottom row) of an n x n grid. the vehicles must be moved to the top row but in reverse order; so the vehicle i that starts in (i, 1) must end up in (n – i + 1, n). on each time step, every one of the n vehicles can move one square up, down, left, or right, or stay put; but if a vehicle stays put. one other adjacent vehicle (but not more than one) can hop over it. two vehicles cannot occupy the same square. calculate the size of state space as function of n.

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
