Question

2) What amount of pressure is felt when your science teacher sits on a seat of nails

which measures 9 in by 9 in? Your science teacher weighs 280 pounds.

Answer 1

23936.5 N/m² or 23936.5 Pa

Step-by-step explanation:

Unit conversion

• inches to meters ⇒ × 0.0254
• pounds to kilograms ⇒ × 0.45

Our dimensions

• 9 inches ⇒ 0.229 m
• 280 pounds ⇒ 127.01 kg

Solving

• P = F/A
• P = mg/A
• P = 127.01 x 9.8 / 0.229 x 0.229
• P = 1244.698 / 0.052
• P = 23936.5 N/m² or 23936.5 Pa
