Depending on what type of power supply it is there are a few options.

If the 2000mA rating means it'll supply up to 2000mA, you're already okay, although you should put a resistor in parallel with the device to safely dissipate extra power. You wouldn't want to exactly split the supply in case the device has current demand variations. It would probably be best to siphon off say, 750mA. Since it's 12 volts, from ohm's law: V = IR you'd want 12 = 750mA*R, or a 16 Ohm resistor. It would also have to handle the power output, where P = IV, so P = 12v*750mA = 9 W. This is a lot of power, but you could probably find such a resistor somewhere. (Try looking at sandstone power resistors)

However, if the supply is powering a sealed device (eg something you wouldn't open up and tamper with), I think you'd be better off just finding the appropriate power supply.

You have media player that uses 5.6v and 2000ma you want to use in your car with a car adapter that has 2000ma with voltage settings of 3v-12v can you safely use the 6v setting or not?

No, it would be unsafe to use theÊ6-volt setting with an media player requiring 5.6 volts. The proper amount of voltage is needed to make sure that the battery is not overheated from too much electric current passing through it.

How can a digital camera be safely removed from a computer?

If you are running Windows, you should be able to go to "My Computer", right click on the device, and select "Safely Remove." There is also an option on the taskbar (bottom right) that should look like a grey pendrive: click appropriate device and select "Safely Remove." If running on a Mac, you should be able to drag the device icon from the desktop to the trash (which should change to an eject symbol as you drag the icon)
