How Do You Convert 0°C To Kelvins Using Significant Figures?

From Mathematics Forum:

How do you convert 0°C to kelvins using significant figures? How do you convert 0°C to kelvins using significant figures? 0 isn't a significant figure, but I already tried answering '0' and it will not work!

Answer: 0 is a constant value, so technically it has infinite significant figures. To convert from Celsius to kelvin, you have to add 273.15, however some people only use 273. So your final answer will depend on the conversion factor you use to get between them.

What About A 0 Gravity Aircraft Cockpit?

From Aircraft Forum:

What about a 0 gravity aircraft cockpit? Does aerospace engineers and scientist are developing a 0 gravity environment for aircraft cockpits which will totally render g force effects ineffective on pilots? As technology increases the capabilities of aircraft exceeds than that the limitations of human body could handle, as what I saw in movie "stealth", UAV's are built for that purpose, to do some maneuvers which a pilot's body is limited to do. Is it impossible to have such technology now? I'm referring to 0 g force effect cockpits.

Answer: If you could build a 0 gravity cockpit, you could build a 0 gravity ENGINE. What your thinking of would be an acceleration Damper, which is WELL beyond our current tech.

What Is Best To File 0 Or 1 When They Take Money Out Of Your Paycheck?

From United States Forum:

What is best to file 0 or 1 when they take money out of your paycheck? I am claiming 0 right now and they take a lot of money out. I have never owed when claiming this and get back about $1,000 when I do my taxes. Is it smart to switch to 1 so they take less out? Of course I want the best way to get me more money.

Answer: If you typically get about $1,000 back when doing your taxes, just go to your payroll dept and ask how much more you would getting per pay period with changing to 1. Then just figure out how much less over the course of a year you'll be paying for federal withholding. By changing from 0 to 1 you'll have less federal withholding taken out each pay period, but you want to make sure that you don't end up owing. To come to about a break even point, you would have to have $19.23 less taken out of your paycheck each week, or $38.46 every 2 weeks if paid bi-weekly. Overall, you're not going to actually end up with more money, you're just getting the $1,000 refund back sooner.

If I Have 0 For Exemptions For State And Federal Taxes Why Am I Being Taxed?

From United States Forum:

If I have 0 for exemptions for state and federal taxes why am I being taxed? My last paycheck had a gross pay of 247.24 and since I am single and only 16 I have 0 for state tax exemption and 0 for federal tax exemption. On all my checks previous to this one they only took Medicare and social security out... now on this last one(which was a lot more than previous checks) they took federal and state tax as well... is this right? and can I change it so that they dint take as much?

Answer: You can claim an exemption. Claiming 0 exemptions means that they are taking the maximum out,. I wouldn't suggest claiming more than 1 though because likely you will owe taxes at the end of the year especially if your parents are claiming you on their tax return. Think of it as a bonus check come next April.

How Does Trigonometric Ratios For 0 Degree And 90 Degree Be Present ,Which Is Not Possible?

From Engineering Forum:

How does trigonometric ratios for 0 degree and 90 degree be present ,which is not possible? How does trigonometric ratios for 0 degree and 90 degree be present, when such triangles do not exist?

Answer: because trigonometry is NOT JUST triangles the ratio is true even if no triangle can be seen. just like air is there even though you cant see it .. cos theta = 0/h doesnt mater how long H is just that the x part is 0 so that means the cos of the angle is 0 so the angle is 90 degs

What Is The Difference Between Waddles Bulls eye 7.0 And Sea chem Liquid Neutral Regulator ?

From Fish Forum:

What is the difference between Waddles bulls eye 7.0 and Sea chem liquid Neutral regulator ? I've been using waddles bulls eye 7.0 and been fine. I would like to use the Sea chem 7.0 liquid Regulator as it is less expensive and will last longer. I have two low tech tanks with java fern and Anubis.

Answer: If you have lo-tech tanks, then I wouldn't even bother messing with your pH. Most of the time, your water is too hard to keep the pH at 7.0, so it'll pop back up to where it was. If you want to keep it more lo-tech, add driftwood and soften your water the natural way.

What Time Of The Year Are 0% New Car Interest Rates Usually Offered By Car Makers?

From Buying & Selling Forum:

What time of the year are 0% new car interest rates usually offered by car makers? We are looking into buying a new car, but really only want to finance at 0% if possible. I'm thinking it might be near the end of the year so dealers can get ride of inventory, but that's just a guess on my part. Also, does anyone know of any car maker currently offering 0% financing?

Answer: Depends on the manufacturer. Some are offering 0% right now on some models (VW, Hyundai, Chevy, Mazda) and some will never offered 0% on any models (Honda). Incentives are based on inventory (supply and demand) and market conditions. It is impossible to determine what the market conditions will be in 6 months, but you can guess based on prior years. 0% is not always the best route if the option is a heavy rebate and you have good credit to keep your interest rate low.

How Would I Find Out If An Unknown Sample Has 0.9570 Mil Of Encl How Many Atoms Of Chlorine Does It Have?

From Chemistry Forum:

How would I find out if an unknown sample has 0.9570 Mil of Encl How many atoms of chlorine does it have? How would I find out if an unknown sample has 0.9570 Mil of Encl How many atoms of chlorine does it have. I dint want the answer really but a guide on how to solve it.

Answer: moles Cl- = 0.9570 x 2 =1.914 atoms of Cl- = 6.02 x 10^23 x 1.914 =1.15 x 10^24

How Much Distance Will A Vehicle Having An Acceleration Of 0-60 Kph Cover In 4 Seconds?

From Physics Forum:

How much distance will a vehicle having an acceleration of 0-60 kph cover in 4 seconds? How much distance will a vehicle having an acceleration of 0-60 kph in 4 seconds cover? Say if the acceleration from 0-60 kph is achieved 4 seconds, how much distance would it have covered at the end of 4 seconds?

Answer: acceleration = a = (60 - 0)/(4) a = 15 km/hr - sec a = (15 km./hr - sec)* (1 hour/3600 sec) a = 0.0042 km/sec^2 Use the formula S = Vote + (1/2)(a)(T^2) where S = distance travelled Vo = initial velocity = 0 T = time travelled = 4 sec a = acceleration = 0.0042 km/sec^2 Substituting values, S = 0 + (1/2)(0.0042)(4^2) S = 0.034 km = 34 meters
