Amass of 30.0 grams hangs at rest from the lower end of a long vertical spring. you add different amounts of additional mass δm to the end of the spring and measure the increase in length δl of the spring due to the additional mass. you plot your data in the form δl (vertical axis) versus δm (horizontal axis). plotted this way, your data lies very close to a straight line that has slope 0.0467 m/kg. what is the force constant k of the spring? use g = 9.80 m/s2

Answer;

B. 3.43 kPa

Explanation;

Pressure is given by the formula;

Pressure = Force / Area

Force is the product of mass and acceleration due to gravity. 

 Thus;  Force = mass x acceleration due to gravity

Substituting;

               Force = (350 kg) x (9.8 m/s²)

               Force = 3430 N

Then, using the first equation;

                Pressure = 3430 N / 1m² or Pa

                            = 3.43 kPa
