Explanation:
In physical science, pressure quantifies the amount of force that is applied at a certain area. Mathematically, this can be transformed as,
Pressure = Force / Area
It is also to be noted that force is the product of mass and acceleration due to gravity.
Force = mass x acceleration due to gravity
Substituting,
Force = (350 kg) x (9.8 m/s²)
Force = 3430 N
Then, substitute this to the first equation,
Pressure = 3430 N / 1m²
<em>ANSWER: Pressure = 3430 N/m² = 3430 Pa</em>
