Answer:
1000N
Explanation:
To calculate the pressure under the box, we can use the formula:
Pressure = Force / Area
In this case, the force exerted by the box is its weight, which is given as 250 newtons. The area that the box rests on is 0.25m^2.
Now, let's substitute the values into the formula:
Pressure = 250 newtons / 0.25m^2
To simplify the calculation, we divide the force by the area:
Pressure = 1000 newtons per square meter
Therefore, the pressure under the box is 1000 newtons per square meter.
To provide an example, imagine a person standing on a wooden plank. The weight of the person would exert pressure on the plank, which is distributed over the area in contact with the plank. Similarly, in this case, the weight of the box is distributed over the area it rests on, resulting in the pressure calculated.
