Answer:

Explanation:

Relation between acceleration a , position s and velocity v.

a = dv/dt

dv/dt= -kv3

. dv/v3 = -kdt

By integration above equation -

∫dv/v³ = ∫ -kdt

-1/2v²= -kt + C

C = integration constant

When t = 0 , v = v₀

C = -1/2v²0

So -

1/v² = kt + 1/v²0  

v = v₀/(ksv₀ + 1)

The correct answer is paper plates.

  1. This question could be simple to answer if you look closely at the answer choices. Cooking and shelter are the same topic, I and II, respectively. They are the main topics of this list.
  2. Shopping list does not exist in this outline, even though we assume this is a shopping list.
  3. Paper plates is the last option remaining. And it is a detail of the outline because it is an item in the bigger section/sub-heading "Non-food items", which is in the main topic "Cooking".

2. Rewrite the following passage, correcting any spelling errors.
Luden [163]

Answer:

It is always a good idea to keep a personal spelling list. You can make it your own vocabulary list too by giving the meaning of the words as well. Spelling doesn't happen by itself, you have to learn it. Reading, of course, also helps you learn how to spell. The more you read, the more words become familiar to you. However, when you are unsure, it is best to look a word up in the dictionary.​ (For the last sentence, you can either put what's above or you can put: "However, when you are unsure, it is best to look up a word in the dictionary.")

Hope this helps!

1. The title begins with just 'Storm' not 'a storm' or 'the storm'. What does this imply​
Airida [17]

Answer:

By leaving out an article (a/the), the title STORM implies a deeper personification of the idea of a storm (whatever it may be in the story). It gives more emphasis on its importance or significance, rather than simply implying that it is "a thing"
