What material where the sound travel more faster?

Sound is a mechanical effect - a transfer of energy from one particle to another by physical (or field) interaction.

Hit a drum and the air by the drum-skin is pushed to and fro by its vibration. That air hits other air, and taht his other air ... and so on. BUT air is not very dense so each moved partical of air may not hit another so losing energy as it moves away from the drum.

This movement should only be called 'sound' when moving air hits your ear-drum and the movement is turned into electrical impulses in your brain.

The speed at which 'sound', or this vibrational energy, travels is affected by the distance between the particles through which it is being sent. If there are no particles, i.e. in space, no sound is transmitted as there's nothing to transfer the mechanical energy ('... in space no-one can hear you scream').

What we find is that the closer together particles are the faster sound is transmited therefore the denser the material is the quicker one particle (or in the case of a solid, an atom) hits the next.

So, in answer to the question it is probably one of two natural elements that have the higest density - Osmium or Iridium who's density is almost the same (appx 22.6 g/cm3) and there are many isotopes so the 'winner' may never be named.

How do you enter some your computer from your computer?

Actually you can access someones computer when your and his computer is connected to internet.

His computer is needed to be configured and configuration ID should be obtained then you can access other computer remotely.

IS THIS GOOD enough for day z and other games please help A M D A Series quad core A8-5600 Processor speed 3.6GHz 12GB RAM 3000GB SA TA hard drive Graphics Shared graphics A M D?

no not really first if you are going to run a apu you need 8 gb of ram at least 2133 mhz or 2400 mhz it doesnt share hard drive it shares ram so faster ram is more fps in game. if you want a decent apu a A10 7850k with 8 gigs of 2133 or 2400 mhz ram. the a8-5600 isnt bad if your gonna play in a really small res like really small. but the good thing about a A10 7850k is your gonna go apu is that you can dual graphics with the r7 240 or r7 250 and if you pair with a 2 gb gddr5 r7 250 and the a10 7850k with 2400 mhz ram its a beast adding a r7 250 and 60% more performance precisely ya it can run bf4 at 1920x1080 with dual graphics at like min fps of 34 to a max of 68 fps. remeber dual graphics is not crossfire its completly diffrent but adds exsactly 60 % performance on the a10 7850k

Does a pc run faster with an ntsf than if you have a fat32?

No, but I suggest using NTFS anyway, as FAT32 only allows files that are less then 4GB. If you use that drive on both windows and mac, however, it is the only way to be able to use it on both.

How do you erase installed games from your PC?

The easiest way is to use the Control Panel Add/Remove programs

This will run the uninstaller that is included with most programs.

If that does not work, then you can remove the program folder from the Program Files directory, but that will not remove other assets that the game may have installed, such as libraries, drivers, and Registry entries. In the case of manual removal, Google for instructions of what to look for with that particular game program.

Can you play just dance 2 on PC?

No, it's pretty much impossible unless you have a pretty good computer with motion censors and stuff like that.

Plus, I don't think the company makes PC games for JD2 anyway.

Are you a human or a computer?

hahaha... your dumb... people answer other people's questions. When you first visit the website before putting in your question look at the website and it asks you if you can answer any of the questions that other people are asking and so many people answer them and that's how you just received your answer to your question ;)

human

Yes, its actually very fun to answer questions. Although, that would be a sick computer that could answer questions this well.

What is the dhcpnack and when do you get one name 2 scenarios?

Recently I saw a lot of queries regarding when the Microsoft DHCP server issues a NAK to DHCP clients.

For simplification purposes, I am listing down the possible scenarios in which the server should NOT issue a NAK. This should give you a good understanding of DHCP NAK behavior.

When a DHCP server receives a DHCPRequest with a previously assigned address specified, it first checks to see if it came from the local segment by checking the GIADDR field. If it originated from the local segment, the DHCP server compares the requested address to the IP address and subnet mask belonging to the local interface that received the request.

DHCP server will issue a NAK to the client ONLY IF it is sure that the client, "on the local subnet", is asking for an address that doesn't exist on that subnet.

The server will send a NAK EXCEPT in the following scenarios:-

1. Requested address from possibly the same subnet but not in the address pool of the server:-

This can be the failover scenario in which 2 DHCP servers are serving the same subnet so that when one goes down, the other should not NAK to clients which got an IP from the first server.

2. Requested address on a different subnet:-

If the Address is from the same superscope to which the subnet belongs, DHCP server will ACK the REQUEST.

The DHCPNACK or Negative Acknowledgment is a packet that the server sends if the IP address is not available in stand of DHCPACK (in use on other client for example) or the address is no longer valid. In case of DHCPNACK the client must restart the lease process in order to get an IP address.

Since computers use base 2 why do humans insist on using the base 10?

we humans use the base 10 because it is easier and more comfortable for us than the base 2 used by computers and as such we require less memory in our brain to fathom the answer of a question and subsequently answer or compute them easily that base 2

There were vertical green gradient like lines appearing all over the PC screen totally randomly sometimes they didn't appear but I didn't find any of the hardwares overheating why?

The cause is more likely interference or a loose connection somewhere. To check for interference you can try and make a call with your cell phone and move it around the computer/ monitor and see if anything happens. Loose connections: Check so that cable is properly plugged in. Jiggle it and see if the lines appear. Replace cable if necessary. Check so that graphics card is also plugged in correctly and not covered in dust. If cable seems ok try knocking on your screen. A little harder. From above and down. If they appear only now you most likely have a defect soldering/connection inside screen.

What does scripted diagnostics native host do?

Scripted diagnostic native host helps your system fetch data stored in it's system . It is a certified windows application if you were wondering.

Why won't Minecraft download on my computer?

You most likely have one of these: 1. if you have a Mac, download the mac version. 2. You have an anti-virus program stopping it. 3. You're firewall might be blocking it because it doesn't have a valid publisher.

What is word length on host machine?

You're talking about words which mean two bytes (16 bits), right? Common computers nowadays are 32bit-based architecture, or what's the same: 2 words. That means a computer with a 1GHz clock timing will do up to 1 million operations per second.

But newer computers are 64bit-based (I think that's where your question comes from) so at first you think: the double... now what? Well, operations are defined in 32 bits, thus in the same time, your 32bit computer does ONE operation, the other 64bit computer finishes TWO. With the same clock timing (1GHz) your new computer does 2 million operations. Cool, huh?

If you, at the same time, give the computer more RAM memory and newer hard disk, your machine will go amazingly fast!

Hope you understand my reply (sometimes I get a bit technical). Tell me if I can help you somehow.
