Question

The diagram below shows three parts labeled A, B, and C, of Earth's orbit around the sun.

Answer 1

Which of these best arranges the parts of the orbit from slowest to fastest speed of Earth in them?

C → B → A

A → B → C

B → C → A

A → C → B

Answer 2

im stuck in between A or C. I need help guys :(

explanation would be very much appreciated

Answer 7

i seem to recall some law that states that the area swept out in a given time frame remains relatively constant.

Answer 8

also consider the pull of gravity .. we fall into the sun, we accelerate due to its gravity and slingshot around it to slow down enough to get pulled back in ....

Answer 9

right, i just read keplers second law :)

Answer 10

now i think it is A nbut im not so sure

Answer 11

lol, i told him to write it :) C is the slowest end, A is the fastest.

Answer 12

haha :) so C B A right?

Answer 13

thats what im going with yes

Answer 14

thank you so much~ can you help me with another? its quite simple subtraction really but i want to make sure i read the question right :)

Answer 15

i can try ...

Answer 16

ok the question is:

what is the difference between the orbital periods of Mercury and Earth?

the table is :
Mercury 0.39
Earth 1.0


since i see the word 'difference'
i istantly thought subtraction so i did this 1.0 - 0.39 and it gave me 0.61 as my answer am i right?

Answer 17

@amistre64

Answer 18

the earth orbits the sun in 1 year

does this mean mercury orbits it in .39ths of a year?

Answer 19

ii guess so

Answer 20

mercury has an 88 day orbital period .... earth is 365

88/365 = .24, not .39

either way, i would say the difference is subtraction yes.

Answer 21

so in this case, my answer would be 0.61, right?

Answer 22

i would agree to that, yes

Answer 23

alrighty :) thank you for helping me

Answer 24

good luck

Answer 25

thanks , ill need it haha
