A box has the weight of 120N and the bottom of the box is 12 cm² what is the pressure the box exerts on the floor
Molodets [167]

100000N/m²

Explanation:

Given parameters:

Weight of the box = 120N

Area of the box = 12cm²

Unknown:

Pressure of the box on the floor = ?

Solution:

Pressure is the force exerted by a body per unit area:

            Pressure = \frac{force }{area}

We need to convert the area into m² from cm²

     10000cm²  = 1m²

      12cm²  =     \frac{12}{10000} = 0.0012m²

 Pressure = \frac{120}{0.0012} = 100000N/m²

When an object/liquid/food etc contains hot energy, the heat particles are moving around causing the heat. 8ounces of soup would cool off faster, because there is less liquid for the heat particles to be in, there for less heat particles, therefore cooling off faster. Pls give Brainliest, and good luck!
