You don't have to set it up. It's already set up. You only have to identify the correct set-up from the four choices.
The correct one is 'B', and it's a formula that you really should memorize.
You'll be using it in any science class that you take.
Weight of an object = (the object's mass) x (the local acceleration of gravity) .
W = m x g
The object's mass never changes. But its weight does, whenever
it goes to places where the acceleration of gravity is different.
That's why the same astronaut has different weights on Earth
and on the moon.

Also, by the way, that bit about the "pendulum bob" in this question
may be there mainly to distract and confuse you. Everything I said
up there above the line is true for ANY object ... a pendulum bob,
a gold fish, a newborn baby, a turtle, a tree, a school-bus, a rock,
a house, a jug of milk, a book, a computer, a burrito, a puppy,
a snowball, an airplane, a cigar, or anything else.
Weight anyplace = (mass) x (gravity in that place)
So base on your question about the moving air and its is cycled in order to reach equilibrium the answer of the questions are the following
A. what are the two major characteristic that change when air is heated and cooled?
-temperature and molecular structure/ phase of the matter
<span>B. how does these characteristics change the movement of air?
</span>-if the air has lower temp the possibility that it will become heavier than with the higher
<span>C. what is the name of the cycle that develop during these changes? Air cycle</span>
<span>D. why do the changes you describe in part B provide an example of a cycle? because of its molecular activity will increase</span>
Red blood cells contain hermoglobin whiles white blood cells do not. Hermoglobin is what gives it its red color.
Answer:
c. It can have a positive or negative value.
She must find her more like herself than you i guess.
