Where does the energy that accelerates a space probe doing a sling shot manoeuvre with e.g. a planet come from? Shouldn't the gravitational drag zero out the pull, i.e. no change in speed?Also, what's /sci/'s opinion on strangelets? does they exist? Supposedly, scientists kvetched over the potential hazard of their their existence, and tried to shut the LHC down. Also, there's been observations that support it, like GRB 240529A, potentially a strange star.
>>16974181Planets orbit the sun. When you come up behind a planet you steal some of its orbital velocity falling down its gravity well, so you can come out the other side faster with respect to the Sun.But just falling into a gravity well won't give you a speed boost coming out the other side.
I got an associates degree 6 years ago and am going back to school to study Electrical Engineering. I took Calc 1-3, Uni Phys 1&2, Linear Algebra, and Diff Eqns before and did well. What should I review? I'm starting this fall and have been studying Calculus BC on Kahn Academy.
I don't know where else to ask thisFor the past year now I have had constant gas, I need to fart every few minutes (not hyperbole) and seconds after I let it out I feel my abdomen tighten and bloat out again from gasI've tried simethicone and it doesn't seem to do shit, any advice?
What keeps our organs in place? Are they just lied down on top each other?
>>16974329You should probably review the hell out of calc 3 and linear algebra at a minimum if you don't want to get raped in your e&m classes. That's assuming your 4 year school accepts your credits from your associate's. If they make you retake those classes that might be a good thing for you long term
if virtual particles pops up as an particle and anti-particle pair every where and then annihilate, shouldn't there be explosions all over the place?
