A tub has a mass of 0.650 kg and 0.350 kg of rocks are put in it. It floats in fresh water with the top of the tub level with the water line. What is the volume of the tub? PLEASE HELP!!!

0.001m^3

Explanation:

Given the following :

Mass of tub = 0.650kg

Mass of rock = 0.350kg

In this scenario:

Upthrust is the weight of fluid displaced

Upthrust = Total weight of tub (since the tub floats, and top of tub is level with the water line )

Recall Weight = mass * acceleration due to gravity(g)

g = 9.8m/s

Total mass = (0.650 + 0.350)kg = 1kg

Weight = 1kg × 9.8m/s = 9.8N

Upthrust = 9.8N

Recall: Upthrust = Density × acceleration due to gravity(g)× displaced body volume of fluid

Density of water = 1000kg/m^3

g = 9.8m/s^2

9.8N = 1000 × 9.8 × Volume

9.8 = 9800V

V = 9.8 / 9800

V = 0.001m^3

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.
