There are many everyday objects that are approximately 20 cm long. Here are some common examples:
Standard Pencil: A typical pencil, like those used in schools, is about 19-20 cm long.
Toothbrush: Many standard toothbrushes measure around 19-21 cm in length, fitting well within the 20 cm range.
Tablet Stylus: Some tablet styluses, particularly those designed for larger tablets, can be around 20 cm in length.
Remote Control: Certain types of remote controls, especially for TVs or sound systems, often measure close to 20 cm.
Ruler: A 20 cm ruler is commonly used in schools and offices, providing a handy reference for small measurements.
These are just a few examples, and many other items can be around 20 cm long, depending on the specific design and use.
Because dollar bills are rectangles, which means they have four sides at 90 degree angles to each other, area is given by side A times side B: 15.5 cm X 6.5 cm = 100.75 cm
We need sound to send information to our ears and brain. Sound is produced when an object vibrates. The air molecules around the object also vibrate. As long as vibrating objects are not in a vacuum they produce sound. So watch your ears.

The mirror equation for concave mirrors is 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. Since the object distance is 10 cm from the mirror and the radius of curvature is 30 cm, the focal length (f) is half the radius of curvature, which is 15 cm. Substituting the values, you can find the image distance (di) which is -20 cm (negative indicates a real image). The magnification can be calculated using M = -di/do, which in this case is -20/-10 = 2. This means the image is inverted and magnified by a factor of 2, located at a distance of 20 cm on the same side as the object from the mirror.
