1) Do single mode fiber optics have a higher data transfer rate than multi mode?1a) If so, why? At first glance it seems that since multi-mode can have multiple light rays transmitting in parallel, it should be able to transfer more dataDoes signal dispersion really impact that much? 2) I'm trying to understand the point of multi-modeI know it's made of cheaper material, so did they compensate by fitting multiple beams in to bring its data rate up to par?3) Also, this may be naive but why not (or do they) make cable with the good quality material of single mode cables and the dimensions of multimode, and send multiple beams over a good quality material cable?
I don't know if it's too easy for the science practical of yours but you can make soapOnly the NaOH can be hard to find25mL of 20% NaOH solution and 20mL of any liquid oil are mixed in a cup and heatedAfter the mixture forms like a dough you can turn off the heatWhen it's cold you should wash it NaCl solution(the salt we use on our meal)After that you should infiltrate itLeave it to dry for a couple of daysP.S: If you use ethyl alcohol in mixture you can quickly see the dough form otherwise you have to heat it so longI hope i could help.
Take a thumb tack (drawing pin) and confirm that it sticks to the magnetThen push the tack into successively heavier objects (for which the weight is known) until you find one that is too heavy to liftMake sure that the objects are not magnetic themselvesOr, you can take a magnetic compass and move it closer to the magnet, charting the amount of deflection you see as the distance between the magnet's pole and the compass decreasesOr you can use a gaussmeter which is an instrument for measuring the magnetic field strength.
One of the strangest fertilizers is NO2It is generated in car exhaustThe environmentalist try to paint it bad , but there is another source and it is lightningEach lightning generates over 200 lband it is very good for the plantsThe plants also recycle the CO2 and give us oxygenIf that is enough the plant keeps the C which breaks down into oil gas.
