Weight of elephant=40000N

Area of one foot = 1000 cm^2

=1000×10 ^−4m^2

Weight of girl=400N

Area of heel of girl = 1 cm ^2

=1×10 ^−4m^2

(a) Elephant has a larger weight of 40000N, therefore, elephant exerts a larger force on the ground. Elephant exerts a larger force on the ground by 40000N - 400 N = 39600 N.

(b) Weight of elephant = 40000N

Area of one foot = 1000 cm^2

=1000×10 ^−4m^2

Pressure= Area/Force

Pressure= 1000×10 ^−4

=)40000

=400000N/m^2

(c) Weight of the girl = 400N

Area of heel of girl =1 cm^2

=1×10^−4m^2

Pressure= Area/Force

Pressure= 1×10^−4

=)400

=)4000000N/m^2

(d) Girl exerts a larger pressure on the ground.

(e) Ratio =Pressure exerted by the elephant/

Pressure exerted by the girl

= 400000/4000000

= 1/10

The pressure exerted by girl is 10 times greater than that exerted by the elephant.
