Acar has four tires that are each inflated to an absolute pressure of 2.0 x 10^5 pa. each tire has an area of 0.024 m^2 in contact with the ground. how much does the car weigh? a. 1.9 x 10^3 n b. 2.9 x 10^4 n c. 1.2 x 10^3 n d. 1.9 x 10^4 n

=72000 Newtons

Explanation:

Pressure=Force/Area

Thus, Force= Pressure×Area

In this scenario, the weight of the car is the force.

The total absolute pressure in the tires is :2×10⁵Pa×4=8×10⁵ Pa

The total area in contact with the ground is:0.024m²×4=0.096m²

Thus the weight of the car=(8×10⁵Pa)×0.096m²

=72000 Newtons

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
