One of the biggest disadvantages is not being able to make connections as easy as the copper. Fiber optic cables have a core as fine as a human hair, making it extremely difficult to splice. Copper cables are obviously not going to be around forever with the fiber optics being so futuristic, but they still have advantages over the fiber. Copper is very easy to work with. When making connections it is so much easier to splice the copper cable than it would be for the fiber.
NT1310 Unit 9 Assignment 1 Transmitters LED Transmitter LEDs have a much lower power output than lasers and LED’s have a larger light output pattern. Which makes it harder to couple into fiber limiting the LED to be used with multimode fibers, LEDs have less bandwidth than a laser and are limited to operate up to about 250MHz or around 200Mbs. With the way LEDs are fabricated they are cheaper to make than lasers, they contain no hazardous material and can last up to 10,000 hours. LEDs have a very small broad output which causes them to suffer chromatic dispersion in fiber. The bulbs create less heat during use, which can lead to lower cooling costs and its green friendly, decreases amount of energy used by 5%.
However, it is expensive to make and is quite large so can be difficult to store. The gradient magnets are 3 smaller magnets within the machine, it is known as the ‘fine tuning’ part of the scanner. These magnets are much smaller than the primary magnets. This part of the machine allows it to concentrate on a certain part of the body. In an MRI machine the gradient magnets create ‘image slices’ of whichever part of the body is being scanned.
Many alternatives are accessible to use. Using other options instead of animals for research come with infinite benefits including less expensive procedures, more animals in their natural habitats, and unharmed organisms. It eliminates the factor of harming animals in order to proceed with scientific discoveries. Sullivan (2012) finds it “less spendy” and faster to use artificial skin and human eye models in addition to the fact they are more accurate methods. These non-animal methods replace those archaic animal tests, and take less time to complete.
(With resistance) Air: with resistance, syringe A can still be pushed a little towards syringe B. this is because particles in air are spread out; there are room in between to particles. That is why when syringe A is pressed down, the particles compressed together tightly causing the syringe to move a little before the particles were impacted too tightly for the syringe to move Water: water particles are different from gas particles. Water has very little compressibility. Particles in water are much more compacted together, therefore giving no space for them to compress more. This is the reason why with resistance, syringe A will not move as the particles in water are as tightly compressed together as they can get.
Society doesn’t lend itself to be studied in a laboratory and this is because it is so complex and cannot be artificially created. It is also difficult to control and identify all factors that could effect behaviour and this is because society id an ‘open system’, not a ‘closed system’. In addition it is hard to match people into control and experimental groups because there will be individual differences
ITT Technical Institute ITT Technical Institute Nathaniel Anderson Nathaniel Anderson Unit 8 Short Answer 4.1 Unit 8 Short Answer 4.1 Title: Differentiating Between File Systems Differentiate between File Allocation Table (FAT) 32 and New Technology File System (NFTS). The differences between FAT32 and NFTS is that NFTS is more robust and effective simple because of its advanced features and functionalities. FAT, in general, comprises of overly simplistic data structures, hence making operations more time consuming. NFTS functionalities are far more-over powering since it makes use of advanced data structures to improve reliability, disk space utilization and overall performance. * When it comes to large USB flash drives, the FAT32 file system is the intended primarily used.
Garraud Sobner General Chemistry, Experiment II 02/11/2012 Questions: 1- In, part I which volume determination was more accurate? Explain. A- 2nd method with the graduated cylinder is more accurate. But not only because we found it more difficult to read the ruler. It was also because we had to take two measurements (one for diameter another for height)...which could possibly create more mistakes.
You might also have noticed that some light bounces off of the glass instead of passing through it – this is because no glass is perfectly transparent to light. Can you use this information to help explain why when it’s dark outside but bright inside (you’ve got the light on) you can see your reflection in the window? 4. The usual method of drawing a light ray is to mark two dots on the path of the light-ray, then remove the ray-box and complete the line. The problem is that the ray itself may actually be a little wide, so it is important that each of the dots is in the middle of the ray; if one is in the middle and the second is a little to one side, the resulting line will not be an accurate representation of the original light ray.
Lack of equipment could’ve been one of factors that contributed to our errors. During this lab, we only had access to one spatula. Due to the lack of time we continued to use this one spatula despite the fact that it may not be cleaned properly and could still be dirty. The dirty spatula could’ve caused our results to be inaccurate because the different samples could’ve mixed causing the color of the flames emitted to vary. Another error that we made was due to lack of equipment once again.
