Q:Is technology (phones, tv, internet, machinery) destroying human relationships?I personally believe it is in little ways. 1.) Advertisements are continually cheapening human interaction. Example: the man who is talking about finding his queen and we think he is talking about a woman but no he is talking about a sofa. 2.) Face to face interaction has become less and less important in society. We are all on our phones, watching TV or on our computers sending text messages or on facebook. 3.) Everywhere you look people are not looking at the person they are talking to, they are too busy with gadgets. I mean who here has been annoyed becuase the person they were talking to was texting?4. We now have more ways than ever to communicate but we are farther apart than we have ever been.So basically my question is, Do you think technology is good or bad for humans?: Yes actually I believe it is also. I went from calling my mother like 6 times a day to sending her and my little sister IM's on Yahoo Messenger, and hitting up their myspace's. We do it more and more since she moved from where I am in Massachusetts to Georgia. Also, I Google everything. A Dictionary, Thesaurus, Phone Book, even Bible I can look up all the information online.

Q:A certain piece of machinery depreciates from 9600 to 8160 in one year. What percent decrease is it?: You have a machine that depreciates from $9600 to $8160 in one year, this can be represented by: Original price - original price*percentage decrease = depreciated amount which is: 9600 - 9600x = 8160 Subtract 9600 from both sides: -9600x = -1440 Divive by -9600: x = 1440/9600 = 0.15 Convert to percentage: 0.15*100 = 15% The machine depreciates by 15% in one year.

Q:In Biology my class is studying Respiration and Photosynthesis in depth (dark and light reactions; electron transport, glycosis, and krebs cycle) and we have an independant project. My problems is I'm not sure what cellur machinery is (he said those is what he calls them). Does it refer to organelles even smaller than mitochondria and the other cell parts (do they even exist)? I'd just like a link or a phrase to google so I know what I should be looking for.: -ose is an ending that indicates a carbohydrate, such as glucose or lactose. How this could indicate cellular machinery is a mystery. About the closest process requiring energy I can think of is cyclosis or endocytosis; both require ATP...

Q:Hi I am an Science Graduate but joined a Manufacturing company as an account assistant. i have a question on depreciation. suppose i am calculating depreciation on a Machine for 5 years. After 5 years the asset value becomes zero. then how we have to treat this asset in Balance sheet. i have to pass an account entry etc... let me know if any one can answer this question clearly as i dont have any knowledge in accounts. please explain in details thank you sooo much: You still treat it as an asset with a value of its original purchase price and under accrued depreciation you show the same (full) amount again, effectively resulting in a zero balance for this item.

Q:Want to know something about some famous machinery enterprises in the world.?: You have to search the internet for further details.

Q:My neighbors just woke me up with extremely loud chainsaws!! Is there some rule about this??: I would say not before 8 on weekdays and 10 on weekends.

Q:My contractor table saw has 2hp motor first starts up caused my lights in my basement to dim and as it running seems like it has some shaking in it, I can feel in the saw table, also the basement light seems to flickering or diming out the whole time when saw is in used. Any idea what is the cause guys. I could use some advice here. By the way this motor is running on 110 volts 60 hertz.: loss of power, [lights dimming] needs its own circuit blade out of balance, ,or loose

Q:being my mind will be wasted in lala land.....with god: It sounds like when you do believe in God it will be too late for you. You won't even think about driving a car where you will be going.

Q:A 20kw,200V shunt generator is operated at rated load. if the driving engine is developing 30bhp (break horse power), determine the iron and friction losses.PLease use all the given data above..thanksAnswer is IFL=1039W.Thanks a lot.: This is the answer I gave to 2 other askers of the same question. brake horse power of an engine is the actual amount of horse power an engine can put out. Using 745.5 watts as a horse power, the engine will supply the equivalent of 30 times 745.7 watts at 30 brake horse power. This is 22,371watts. The generator is supplying 20 Kw or 20,000 watts. The difference in the engine output and the generator output is 22,371 minus 20,000 or 2.371 watts. I don't see how the answer is 1039 watts, if my calculations are correct. Perhaps someone else will have the answer you seek. I may be missing something in your question
