The four tires of an automobile are inflated to a gauge pressure of 88500 Pa. Each tire has an area of 0.0276 m2 in contact with the ground.

WEight=Numbertires*pressure*area, right?

To determine the weight of the automobile, we need to use the formula:

Weight = pressure × area

Given:
Gauge pressure = 88500 Pa
Area = 0.0276 m^2

Substituting these values into the formula, we can calculate the weight:

Weight = 88500 Pa × 0.0276 m^2

Calculating this, we get:

Weight = 2436 N

Therefore, the weight of the automobile is 2436 N.
