Is this the help that I think it is? Wink wink

Lern object oriented java and make sure u didn't forget 2 unit calculus cuz

The question was something like "How can two's compliment be useful in subtracting numbers". I said that if the number being subtracted is changed to negative (using 2s compliment) and add the two numbers, you are effectively adding a negative number to a positive number - subtracting the...

the transformer that works with two coils creating and picking up a magnetic field won't work with batteries or any other DC because AC is required to create the magnetic field. there are dc boost regulators but they would not be stable on a saltwater cell. make many cells and put them in...

2ez Floating point methods like the IEEE 754 are just approximations of real numbers. They need to be converted to fixed point or integers before being processed - taking more CPU time. I just looked it up and control characters are characters like \n which tells the printer to move the page...

For the login question I just counted failed attempts, not worrying about who's failed attempt it is. Do you think it is possible for me to get full marks for that question? Does anyone know what the book chapter question was asking from us?

i ain't no engineer. the magnet will have to spin pretty fast to even power an LED. i would get the ratios working or think of another idea if i was u. if you get 2 motors, connect their axels together, power one, and connect an LED to the other you would have a electric -> kenetic -> electric...

You need to make it so that the magnet spins quickly even when the handcrank itself is moving slowly. Did you see my picture in your other thread?

someone linked me these solutions http://www.projectacademy.com.au/2014_HSC_Maths2UAdv_Solutions.pdf

Thanks. I was wrong

wow. i skipped part ii and iii - and im luck i did I probably put D as well. just didn't recall properly Are you sure that 10 is D? I thought it was A

hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm are you sure? it says 'at least one'. I thought multiplication is for when all of them are true. I added them together to get a as it is EITHER of those probabilities.

These are all from memory. Im not working any out again lol 1. A 2. B 3. D 4. C 5. B (i think) 6. D 7. B 8. A or D (the answer is B or C lol i fkd up) 9. A 10. A Did I mess up anywhere?

If you're going with the handcrank thing then you also might want to look into a bridge rectifier and a small value capacitor. The bridge rectifier you can make out of 4 diodes. It will allow you to spin the motor clockwise AND anti clockwise while still lighting the LED up. The capacitor will...

HELLOW

still doge

then put an LED on that shit and spin it lol. ideas will definately come to your brain

You can purchase them online but I think the point of this is to show something you have made, not just something you bought and attached an LED to. http://www.aliexpress.com/cheap/cheap-dynamo-motor-generator.html http://www.electroschematics.com/9784/hand-crank-generator/ Those motors need to...

Cheese + sriracha jaffle i know it's probably not good for you; maybe adding a slice of tomato will fix that? this sauce is also good. make sure to get the one that says "GARLIC". others are crap

Even better. Make it in Minecraft using Redstone logic! (statutory warning: Minecraft is in no way affiliated with Technoash. Minecraft may have withdrawal symptoms, cause square eyes and/or devour your free time)
