what is the speed of light?
google it if you don't know and post it here.
ttully, are you interested in the answer or not? I need your feedback to help you.
yes i will google it
the speed of light = 299 792 458 m / s
okay. to make matters simple, we generally assume the speed of light to be 300000000 m/s or 3X10^8 m/s so, what is Warp 8 then? What is that speed equal to?
just tell me what Warp 8 means. Unless you don't want the answer. In that case I won't waste your time or mine.
I dont know what warp 8 means
it is given in the first sentence of the problem. read it.
8 times the speed of light
8 X 299 792 458
you must always say what that number means. 8 X 299 792 458 could mean feet, or pounds or number of fish you caught last year. what is it?
8warp X 299792458m/s
no, you should say Warp 8 = 8 X 299792458m/s
okay. so we have the speed. now, what is the distance traveled in a year? the formula for distance is speed X time. so how much time is one year?
okay, that is the speed. now, what is the time?
okay. how long is a year?
okay. and how many days in each year?
really? when was the last time you had 360 days in a year. A year has 365 days. Look it up.
anyway, how many hours in a day?
and how many seconds in an hour?
are you sure? 1 hour is 60 seconds long?
right, and each minute has how many seconds?
okay. so a minute has 60 seconds. and hour has 60 minutes, a day has 24 hours. a year has 365 days. so the total number of seconds in a year is 60 X 60 X 24 X 365
so give me the number of seconds in a year. Multiply all that using your calculator.
okay good. so if you are traveling at warp 8 it means that you travel 2398339664 meters each second. so how much distance would you travel in 31536000 seconds?
oh. you travel 7.563403964? what is that? is it 7.5 feet? or 7.5 kilometers, or 7.5 pounds of meat? or 7.5 chips?
so your answer is 7.5 miles?
no it is 7.5miles X 10 to the 9th power
is that right? and how did you get that answer?
I dont know if that rigt or not. But I mad the 7.563403964 into scientifice notation
well, if I told you I travel 1 foot every second, how much distance will I cover in 10 seconds?
why not 10 miles?
because you said 1ft a second
right. if you travel at warp 8 speed it means you travel 2398339664 METERS each second, how much distance would you cover in 31536000 seconds. Why did you say 7.5 X 10 ^9 MILES?
how come you changed meters to miles?
because it has to be in scietifice notation
what did you think scientific notation means?
its so you dont have to use so many numbers
actually, don't worry about the scientific notation now. just tell me how many METERS it travels in one year.
are you sure? it travels just 7.5 meters in one whole year?
no im consfused now
if my speed is 10 meters per second, how many meters would I travel in 10 seconds?
are you familiar with meters? it is just a measure of distance. One meter is roughly equal to one yard. so don't get confused by the word 'meter'
so answer my question: if my speed is 10 meters per second, how many meters would I travel in 10 seconds?
wrong. do you know how distance is calculated? distance is speed X time
so if my speed is 10m/s, how much distance would I cover in 10 seconds?
100 what? feet, seconds, pies?
okay. so if my speed is 10 m/s, I travel 100 meters in 10 seconds. Using the same logic, if my speed is 2398339664 m/s , how many meters do I travel in 31536000 seconds?
okay. so 7.563403964E16 meters is the answer. That is also the scientific notation. Scientific notation simply means you take a number, say 123455 and express it as 1.23455 X 10^5. so the answer in your case is 7.563403964E16 which can also be written as 7.563403964 X 10^16
all in meters.
The letter E in the answer means you multiply the number before E with 10^ the number after E so 7.563403964E16 means 7.563403964 multiplied by 10^16. so your answer in scientific notation is 7.563403964E16 meters or 7.563403964 X 10^16 meters.
http://www.chem.tamu.edu/class/fyp/mathrev/mr-scnot.html http://en.wikipedia.org/wiki/Scientific_notation scientific notation is just a way to represent NUMBERS. It does not mean that you should change meters to miles or anything like that.
ok thank you
you are welcome. note that E means the exponent. it doesn't always have to be 10.
