19. You must give all answers (correctly) to receive beta key
Part 1: A broodlord is traveling at speed 0.9c along the x axis of frame S. It shoots broodlings traveling at a speed (3/4)c relative to the broodlord. What is the speed of the broodlings relative to S?
Part 2: The height of a dead cat at perigee is 300 km above the Earth's surface and it is 3000km at apogee. (a) Find the orbit's eccentricity. (b) If we take the orbit to define the xy plane and the major axis in the x direction with the Earth at the origin, what is the satellite's height when it crosses the y axis? (c) Do you like cats?
Part 1. 0.985c
Part 2.
Assume Earth's radius is 6368km (an average)
a) e = 0.168
b) 300km
c) Yes I like cats

1) 0.985c
2a) Ecc. = 0.17
2b) Height = 1424 km
2c) Yes

btw in #19 2b) shouldnt the Earth be at one of the foci?
it is

clue 19
1) 0.985c
2a) e = 0.995
2b) 300km
3c) no
to cover my bases ^^;

Btw there is a big difference in eccentricity of .17 and .1683. The kind of difference that causes satellites to land in your back yard.

From what i can tell there have been two answers for #5 and one for #6 although the #6 guy forgot to post his name ingame so it may or may not count. #7 should still be open if anybody wants to make an attempt. Good luck! Pretty sure there is multiple entries for #7.
Thanks for the heads-up. And happy birthday!

18) Need more DATA!
Based on the serology provided: Chronic HBV, either High or Low infectivity
+ HBsAg indicates the person is indeed currently infected with Hepatitis B Virus. The + Anti-HBcAg IgG indicates the infection is chronic.
What you are missing is the status of HBeAg and Anti-HBeAg, the presence of HBeAg would indicate HIGH infectivity and Anti-HBeAg indicates LOW infectivity.
Wait... wtf. Wouldn't the fact that both HBsAg AND anti-HBc (lgG) are positive point that there is no infectivity?
Can some correct me on this?
And I also showed the patient's diagnosis on HAV(immunity) and HCV(no current infection) on my other post.
If I'm correct on the HBsAg and anti-HBc (lgG) being enough markers to determine no infectivity, can I get the beta key?
Thank you very much.

i m currently trying to beat 9 terrans on bgh =( i helds em off for 13 mins and died =(((

18#
negative anti-HAV IgM
negative anti-HAV IgG
positive HBsAg
negative anti-HBsAg
positive Anti-HBc IgG
negative anti-HBc IgM
negative anti-HCV
He is a chronicaly infected porter of hepatitis B

how do you even play vs 9 terrans?

(part 1): 1.2c
(part 2): 9/11(.8182) eccentricity. 948.68Km. Yes
i think >.>

...The cat is the satellite. "In the context of spaceflight, a satellite is an object which has been placed into orbit by human endeavor..." This question was in the context of spaceflight, and the cat was placed into orbit by human endeavor, since we can safely assume that the cat did not get there by itself.
Thus, the answer is not "there is no satellite in the question."
