Question 3 of 25 The diagram below shows the path of a comet around the Sun.
HEL PLEASE

How does the comet's energy change as it moves from point A to point D?
OA. KE increases, GPE increases
OB. KE decreases, GPE decreases
O C. KE decreases, GPE increases
OD. KE increases, GPE decreases

Explanation:

You didn't post the diagram so nobody can tell you the exact answer. However, I can give you an explanation that might help.

Kinetic Energy (KE) and Gravitational Potential Energy (GPE) are oppositely proportional. Meaning if one goes up the other goes down. So they can't both increase or decrease; meaning A and B aren't options here.

Next, KE will go up if the comet gets closer to the sun. And GPE will go up if the comet goes further from the sun.

So with that in mind, look at your diagram and see what happens between Points A and D. If it gets. loser to the sun, then the answer is D. If it gets further from the sun, then the answer is C.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
