The bottom of a box has a surface area of 31.4 cm2. the mass of the box is 47.1 kilograms. acceleration due to gravity at sea level is 9.80 m/s2. what pressure is exerted by the box where it rests?

14.7 n
1.5 n
0.153 n
6.53 n

Pressure = 147,000 N.

Step-by-step explanation:

Given : The bottom of a box has a surface area of 31.4 cm². The mass of the box is 47.1 kilograms. Acceleration due to gravity at sea level is 9.80 m/s².

To find :  What pressure is exerted by the box where it rests.

Solution : We have given that area of box = 31.4 cm²

First we convert it in meter².

1 meter = 100 cm

31.4 cm² = 0.00314 meter².

Mass of box = 47.1 kg

Acceleration due to gravity = 9.80 m/s².

According to Newton second law of motion , F = mass * Acceleration due to gravity.

F = 47.1 * 9.8

F = 461.58 Newton.

Pressure = .

Plugging the values of force and area.

Pressure =  .Pressure

Pressure = 147,000 N.

Therefore, Pressure = 147,000 N.

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
