How do Americans (US) pay their taxes and how do they know how much to pay? | Okay. So Americans have sales taxes, but we also have an income tax.

However,... |
Why are court sentencing sometimes done at a later date, even when the defendant is already found to be guilty? | Sometimes it does occur at the time a plea is entered - it depends on the complexity of calculating the sentence.

Were enhancements such as... |
How does a set of ones and zeroes (coding) correspond into a physical object in a game? | Think about how you express a physical object in English.

what parts of the spectrum does a mirror reflect? Can a mirror be melted by any part of the spectrum? | The reflected wavelengths depend on the mirror as already mentioned. An interesting way to see this is with the now more commonly available thermal imaging cameras.

WiFi is sporadic in nature, relying on signals that have to pass through air and walls means you certainly won't get 100Mbps even if you're the only one connected to your access point. Distance from your router is also a factor.... |
