Hi i am male about 140kg (a lot of muscle included) and 190cm tall, i currently walk about 6 kilometers per day. How much energy could i burn or weight could i lose by walking 6km everyday or 5 times a week maybe? I am also eating a lot less carbs, fat and sugar in my diet, along with less food/smaller portions.

So i've got this little peavey vypyr 15 watt combo amp, its brilliant and i can get killer tones and all, but would i notice much difference if i got a guitar with emg pups on it like this one: http://www.espguitars.com/guitars/ltd-standard-del... it has an emg 81 at the bridge and a 60 at the neck.

ok. So i've installed left 4 dead 2 from a disc through steam (like i have a choice anyway) and after ive installed it, i try to play it, but it has to update before i can play it which is fair enough except it says ive downloaded 51% (presumably this is from installing the game from the disc) and i have to download an additional 5gb even though ive installed the game and it takes up about 6gb. surely this cant be right. what is going on? is there another way to install it?

i was looking at a review of the gigabyte 5870 graphics card http://www.atomicmpc.com.au/Review/167504,gigabyte... and i looked at the benchmarks and saw that the fps for crysis look unusually high for a single card, are these benchmarks correct?

This may sound stupid or far-fetched, but i don't know much about integrated graphics. we all know about crossfire and sli for having multiple video cards in one pc, but what if motherboard manufacturers could put about 4 integrated graphics chips, to increase video performance. looking at this article here http://www.anandtech.com/show/3871/the-sandy-bridg... the new sandy bridge graphics chip competes with a 5450, so it would be worth having more than one sandy bridge. Even though integrated graphics chips don't have their own dedicated memory, having enough RAM wouldn't be a problem because its abundant today. would my idea be possible?

right now modern games use around 1gb of ram, but when will new games start using much more like 4gb?

I did an experiment on how the density of an object affects how much it's affected by air resistance when falling (if that makes sense). I have a graph with time of fall on the y-axis and density on the x-axis. Here's what i have plotted

y = 4.83 when x = 93.918

y = 3.63 when x = 204.36

y = 2.90 when x = 709.00

y = 2.75 when x = 1128.8

so is this relationship inversely proportional or a negative linear line?

What are some of the advantages of using various parts of the electromagnetic spectrum for observation?

in astronomical observation, how are the red shift and the dopple effect used?

How does the earth's atmosphere have an effect on astronomical observation and how are these effects overcome?

Quake 3 is fine on single player, but when i do multiplayer over the internet i shoot a bullet, i can hear it and then the bullet is fired from the spot i was about 1 second later. Why is it doing this and how can i fix it?

I want to know what speed the Intel core i7-920 lga1366 2.66Ghz can be overclocked to with the stock fans in an antec 900 case. Any help would be appreciated.

I'm thinking of building a gaming pc and i'm wondering what processor i should use out of these 2.

Intel Core i5 661 3.33Ghz 4Mb Cache 2 Cores/4 Threads Turbo Boost

or Intel Core i5 750 2.66 Ghz 8Mb Cache Quad Core 4 Thread Turbo Boost

do i really need 4 cores and an 8mb cache for gaming?

and Could you please recommend a good gaming motherboard to go with this?

sorry i'm fairly new to building PC's - this is my first

I'm running vista with a pentium dual core T2310 (1.46Ghz), 1 GB of ram, 251 mb of integrated graphics

Will the game quake 4 run on my computer? it requires pentium 4 2.0ghz is my processor the equivalent or better than that?

Microsoft word, Itunes, Quicktime, Windows live messenger and more programs have stopped working How can i fix this? Any help would be greatly appreciated because i need these programs.

I'm running vista if it helps.

I'm currently using alcohol 52% to run a DVD-rom game (my other computer does not have a dvd drive) and the game takes long to respond when i move the mouse or press any keys. Is their a way of speeding up how fast a virtual cd runs with alcohol 52% or any other program? To play the game i need to be able to run the virtual cd at x16. I currently do not know how fast the virtual cd is running. If their is a way of speeding a virtual cd up please tell me the program to use or how to do it with alcohol 52%.

I have all the recommended specs for the game except the DVD drive of course so you can't tell me to upgrade my ram or anything like that.

i ran a prime95 torture test to see if their were any errors before i overclocked my laptop's cpu. Their were no errors, but i saw that my core temperature got up to about 84 degrees celcius (i think it was celcius anyway). Should i overclock and if i could is their a way of just increasing the multiplier from

11 x 133MHz to 12 x 133Mhz (intel pentium dual CPU T2310 @ 1.46GHz.)

I know this is kinda two questions but i really need help. thanks.

how would you rearrange A=x(1/2)^n to get n? It's a nuclear physics formula?

A=current nuclear activity

x=original nuclear activity and

n= number of half lives elapsed.

i have to write a blog and i'm wondering if i have to use formal language or slang and abbreviations

does heat make it stretch further or what?
