Colin is helping a librarian return books to the shelves where they belong. He picks up books from the librarian’s desk, as shown in Figure A. He then carries them to the shelves, as shown in Figure B. Circle the words that correctly complete the paragraph. 9. In Figure A, suppose that Colin drops a book. Then some of the (kinetic / potential) energy of the books changes to (kinetic / potential) energy. Energy is (conserved/ gained / lost), because the total amount of energy of the books (decreases / increases / stays the same).- Help Fast my Test Starts soon

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
