Two sides of a rectangular table are 0.8 m and 1.2 m, the displacement of spider when it runs a distance of 2.0 m is
A)1.5 m
B)1.4 m
C)1.6 m
D)1.7 m

The displacement of the spider is the shortest distance between its starting and ending points, which can be found using the Pythagorean theorem. Since the table is rectangular with sides 0.8 m and 1.2 m, and the spider runs a total distance of 2.0 m, it's not directly related to the total distance run but the diagonal it might cover. The diagonal (displacement) can be calculated as the square root of the sum of the squares of the sides: sqrt((0.8)^2 + (1.2)^2) = sqrt(0.64 + 1.44) = sqrt(2.08) ≈ 1.44 m.
