Rank the following in terms of increasing pressure: a. a 10 kg object distributed on a square surface with dimensions 10 cm by 10 cmb. a 20 kg object distributed on a square surface with dimensions 10 cm by 10 cm c. a 30 kg object distributed on a square surface with dimensions 20 cm by 20 cm d. a 40 kg object distributed on a square surface with dimensions 30 cm by 30 cm

Answer;

In order of increasing pressure;

D < C < A <B

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

nah.   i'm just sleepy.

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
