Use dimensional analysis to convert the following units. Show your work. 1) 2.5 days to seconds
2.5 d
2) 25 km to mm
3) 22g to kg

Explanation:

conversion of 2.5 days to seconds

2.5 days =2.5 days*24 hours*3600 seconds

2.5 days=216000seconds

b) conversion of 25 km to mm

1 km=1000000 mm

therefore

25 km=25*1000000=25000000 mm

c) conversion 22 g to kg

1000 g=1 kg

therefore

22 g=22/1000=0.022 kg

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.

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.
