How many are being used? All of them. If the screen is a 1280 x 1024, that's 1,310,720 pixels.
There is no fixed number. It depends on the product (computer monitor, TV screen, digitial camera) and the model.
A discount LCD monitor has around "1920 x 1080" pixels but this may vary by the type of flat screen television you have as all televisions are not the same. A standard monitor will have the lowest possible settings for pixels.

This question cannot be answered without further information. There are hige variations in the number of pixels in a digital camera, a TV screen, a computer monitor. In each case a different number of them will equal 1%.
That depends on the resolution of the screen the pixel is on. An old tv has a lot less pixels than a modern wide screen computer monitor.

The amount of pixels is defined by your monitor, not Excel or whatever application you use. So in landscape mode on different monitors, you would have different amounts of pixels.
A pixel is one of many small dots that are found on a TV screen or computer monitor. These small dots are what make the picture on the screen. The more pixels there are, the clearer the screen.

The number of pixels in an average header can vary widely depending on the website design and purpose, but a common size for a website header is around 1200 pixels wide by 200-300 pixels tall. This results in approximately 240,000 to 360,000 pixels. However, headers can be larger or smaller based on the specific layout and responsive design needs.
That depends on a lot of things including font type, font size, monitor size, and resolution.
A computer monitor typically consumes around 25-30 watts of power.
