- Q: DUE TONIGHT PLEASE HELPA 90 kg astronaut floating out in space is carrying a 1.0 kg TV camera and a 10 kg battery pack. He's drifting toward his ship but, in order to get back faster, he hurls the camera out into space (away from the space ship) at 18 m/s and then throws the battery at 11 m/s in the same direction. What's the resulting increase in his speed after each throw?speed increase after discarding camera.?speed increase after discarding battery?
- The key here is to remember that momentum is conserved. Momentum is mass times velocity. Are you sure you've got the masses right, surely the TV camera is heavier than the battery pack? Since (relative to each other), neither astronaut, nor camera nor battery is moving, the total momentum can be taken to be zero. So after throwing the camera away, the total momentum should be zero m/s. That means the astronaut should have equal momentum in magnitude, but opposite in direction, to the camera. Let's take the direction the camera was thrown in to be negative. Then the momentum of the camera after it is released is (1.0 kg)(-18 m/s) -18 kg m/s. So the momentum after discarding the camera must be 18 kg m/s. Dividing by the mass of the astronaut (plus battery pack, as he's still got it at this point), which is 100 kg, gives an increase in speed of 0.18 m/s. Now we do the same thing with the battery pack. Since, relative to each other, neither are moving, we can say that the total momentum before releasing it is zero, so the total momentum after releasing it must be zero also. The momentum of the battery pack, since it is thrown in the negative direction also, is (10 kg)(-11 m/s) -110 kg m/s. Therefore the total momentum of the astronaut must increase by 110 kg m/s also, and dividing by the mass of the astronaut (90 kg) gives a speed increase of 1.22 m/s.
- Q: Hi. I accidentally used the wrong charger on my sony np-bn1 lithium ion battery for about, say, 30 minutes, and then realized I was using the wrong one, switched to the right one.A few hours passed, and now i have a problem where if i put it in my camera, it'll stay on for 5 seconds, and then say For use with compatible battery only.Plz help.
- I'm afraid you cooked it. Be more careful with your next battery - there's no fixing this one.
- Q: I'm asking this because when i leave the battery pack in the Xbox there is this faint green light shown in the circle, does this waste battery?
- very confusing issue. try searching into google and yahoo. it will help!
- Q: I saw an advertizement for a charger that charges your cell phone when you are on the go. It's by enigizer. I really want it , my battery is constantly going out. Does it fit all cell phones? Where would I find it?
- Yeah,I Just Saw one of those in CVS.There $19.99 And They come with two(2)Energizer Batteries.And No,They Dont fit all cellphones.They only fit the ones who have a circle for a charger import. So if you have a Razr phone,then It wouldent do you any good.
- Q: Hello, I just recently bought a dual docking station with 2 battery packs for my regular wiimote and now I want to buy a wiimote plus (built in motion plus) but since the wiimote + is longer and I've never seen one in person I don't know if my regular docking station and battery packs will work and fit the wiimote+ or will I need to buy special battery packs and docking station for it? Thanks alot for answering!
- the wii remote and the Wii remote plus are the same size. the only reason the wii remote plus is ever longer is because to make the senor work better ( the pluse part) you need to attach a large block to the end of the normal remote. the remote with it built in is the same size.
- Q: I have a rechargeable battery pack. when i plug in my plug n' play charger, the red light comes on but i still cant even turn on or connect my controller. The whole console has been in storage for a while.
- Battery packs sometimes go bad . I bought one and it went bad in 3 months and would not charge or make connection to xbox. Microsoft does not make the best accessory's.
- Q: 18650 battery pack how to package package?
- Prepare the relevant materials: batteries, nickel, protection boards, wires, green nude paper, PVC.
- Q: Why some ups battery pack to take the middle of the tap?
- Mainly by the high-frequency UPS rectifier charger on the battery charging method of the decision.
- Q: I bought a 4 pack of AA batteries at the grocery store the other day and thought I forgot them in the cart because I couldn't find them. Well today I found them in my freezer. Must have accidently thrown them in while putting away the groceries. Can I still use them?
- It will do no harm to try to use them. Bring them up to room temperature slowly - just put them in the kitchen for a couple of days. Dry them off frequently when condensation forms on them. Then simply try them.
- Q: I just rebuilt a battery pack for my laptop. I took out the old Li ion batteries (which were 2600mah each) and replaced them with the same kind of battery (18650) except the new ones had 4000mah each. I kept the original circuit board, and did the same connections. I didn't have a millimeter though to test them (I know bad)I charged it overnight, it showed in the operating system that it was charging, and after 20 hours of charging, it said low vary after 20 min (where it used to die), but lasted 40 minutes after this for a total of 1 hour. What is going on?Laptop is msi gx630Thanks for your help, I'm clueless, is it from a weak solder joint?
- your conclusion that the fault was with the original 2600mah batteries might be incorrect. I know it is quite likely but if it is incorrect, that would explain why batteries you believe are perfectly good are not retaining a charge. The supporting circuitry or perhaps even the motherboard bios could be the problem. The big question is: Are other owners of this model having the same problem? Search on the internet by typing gx630 batteries don't hold charge or something like that. Li Ion batteries sometimes need to be cycled several times to extend their charge time: charge all the way up, run down completely, 3, 4 times. Observe the results carefully to detect any change.,
