Question

Show formulas and Rank the following from highest pressure to lowest pressure upon the ground: - The atmosphere at sea level - A 7000-kg elephant with total area 0.5² in contact with the ground - A 65-kg lady in high heels with total area 0.005 m² in contacting with the ground - A 1600-kg car with a total tire contact area of 0.2 m²

Answer 1

The highest pressure to lowest pressure upon the ground is the atmosphere at sea level, a 7000-kg elephant, a 65-kg lady in high heels, and a 1600-kg car with tires.

Step-by-step explanation:

The order of highest pressure to lowest pressure upon the ground is as follows:

1. The atmosphere at sea level: The atmospheric pressure at sea level is about 1.01 × 105 Pa, equivalent to 1 atm.
2. A 7000-kg elephant with a total area of 0.5² in contact with the ground: The pressure exerted by the elephant is 14,000 lb/in².
3. A 65-kg lady in high heels with a total area of 0.005 m² in contact with the ground: The pressure exerted by the lady is 30 lb/in².
4. A 1600-kg car with a total tire contact area of 0.2 m²: The pressure exerted by the car is calculated by dividing its weight by the tire contact area.
