I don’t know how fast asteroids travel, so lets just say it’s moving at an “average” speed and it’s large enough to wipe out all life on earth. Would this asteroid be visible to the naked eye for any significant amount of time before impact? Hours, days, weeks? Nighttime only, or daytime as well? I’m doing research for a sci-fi story and can’t seem to find an answer to this. Thanks in advance to anyone who can help.

I can, so could houdini, but I don’t know anyone else that can. I can leave it there (and talk) then swallow when I want too. It’s strange but Im realizing that it’s not as common as I thought.
Take a gram of (highly enriched, weapons grade) uranium. If it is caused to explode in a fission reaction, it will yield X amount of energy.
At what speed would an identical gram of uranium have to be traveling such that it’s kinetic energy equaled X. Or, perhaps, that at impact it’s kinetic energy equaled X.
Traveling in outer space, of course. This question occurred to me while watching a show on asteroid impacts. [No, I am not in school and lazy. I just don't know physics, but do know how to phrase a question.]
This is a poll for my college class. Its very short, but I need 50+ people to answer. I know i won’t get that many here, but any amount helps because I’m working 2 shifts tomorrow AND have to study for my finals.. so I won’t have the time to go out.
If you don’t want to answer — please vote on an answer you would have chosen and I’ll just Tally em up.
Based on the information below, which person would you want help from?
Q: You are stranded in the Amazon. While walking thru the dense jungle, you come across a stranger. They offer you help, which you gladly accept. Out of the choices below, who would you accept help from?
A. A convicted murderer/bank robber.
Pro: They have a map, water and knowledge of the area. They offer to guide you back to the ranger station.
Con: You notice this person eying your valuables, you saw a WANTED poster back at the ranger station. The WANTED poster read: “Do not approach this subject. Armed and very dangerous”
B. A native
Pro: Knowledge of the area and survival skills.
Cons: You can not understand their language. You are unsure if this person is friendly or not. they are pointing a very large spear at your throat.
C. A person with a severe Bi-Polar disorder
Pro: Has supplies with them (water, food, first aid kit).
Con: This person is without their medicine. They have become very unstable and are becoming increasingly violent and suicidal. This person is carrying a knife.
Just put your answer, A, B, or C. If you’d like to include a reason, as to why you picked that person, that would be a big help. Plus, i’m a little curious. lol
Thanks
For example: picture an aging scholar who has learned as much as he can throughout life. Will he subconsciously start permanently forgetting certain “less important” things he learned in the past (I don’t know, maybe like certain math or sciences skills, or pointless skills not needed for survival or something), in order to “make room” in his memory for the new things he’s currently learning?
Please note that senility, Alzheimers and any other elderly or memory disorders/diseases are not the answer I’m looking for. I only used seniors as examples for this question since I doubt anybody of youth would likely be wise enough, and have had enough time and energy to fill their entire memory “in-box” in under 60 years.
