1. Alice decides to measure the density of the banana. a)What equipment will she need to measure it?

b)Explain how she could use that equipment to measure the density.​

A) Measuring cup with water and a scale

Explanation:

Fill the measuring cup with water to a certain point, and record the current height of the water. After placing the banana fully into the water, record the new height of the water. Subtract the old height from the new height. Now you have the banana's volume.

Then, place the banana on a scale to get it's mass.

Perform , where p = density, m = mass, v = volume.

Note: 1 milliliter = 1 centimeter^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.
