The resolution of digital camera 104 is 20.1 megapixels. This means that the camera is capable of capturing images with a high level of detail and clarity. The higher the resolution, the more pixels are packed into the image, resulting in sharper and more detailed photographs. This makes digital camera 104 suitable for capturing high-quality images for various purposes, including professional photography and printing. **

Anna can prove that 891 is a number by showing that it is a mathematical concept representing a quantity. She can demonstrate this by writing it as a numeral, showing that it can be used in mathematical operations such as addition, subtraction, multiplication, and division. Additionally, she can show that 891 fits the criteria of a number, which includes being a whole, rational, and real number. **

A regular clamp is a simple tool used to hold objects together, typically made of metal or plastic with a screw mechanism to tighten and secure the object. On the other hand, an Ottoman clamp is specifically designed to be used on furniture, particularly on the corners of ottomans and other upholstered pieces. Ottoman clamps are often larger and have a wider grip capacity to accommodate the thicker and softer materials used in furniture construction. Additionally, Ottoman clamps may have protective padding or covers to prevent damage to the furniture during clamping. **
