Gaige Mccann · Answer 1

Answer;

In order of increasing pressure;

D < C < A
B, has the highest pressure while D. has the least pressure

Explanation;

Pressure = Force / Area

10 N = 1 Kg

Therefore; for

B. A 20 kg object distributed on a square surface with dimensions 10 cm by 10 cm.

Pressure = 200/100

= 2 N/cm²

A. A 10 kg object distributed on a square surface with dimensions 10 cm by 10 cm.

Pressure = 100/100

= 1 N/cm²

C. A 30 kg object distributed on a square surface with dimensions 20 cm by 20 cm.

Pressure = 300/400

= 0.75 N/cm²

D. A 40 kg object distributed on a square surface with dimensions 30 cm by 30 cm

Pressure = 400/900

= 4/9 N/cm²
