1The map below shows a portion of an island. The elevations shown on the island are in meters. Explain how the contour lines shown on the map can be used to determine which area of the
island has the steepest slope.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
