A woman drives a car from one city to another with different constant speeds along the trip. She drives at a speed of 95.0 km/h for 15.0 min, 60.0 km/h for 20.0 min, makes a stop for 50.0 min, then continues at 40.0 km/h for 30.0 min, at which point she reaches her destination. (a) What is the total distance between her starting point and destination (in km)

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.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

find the surface area of the sphere to the nearest square unit. use a calculator.
