I presume you mean cm2, which means square centimeters, a unit of area. Millimeters (mm) are a unit of length, so you cannot convert one to the other. You can convert cm2 to mm2. Since there are 10 mm in 1 cm, there are 100 mm2 in 1 cm2. So multiply by 100.

Actually, the speed of light is affected by the medium it travels through. The speed of light in a vacuum is a constant. It moves slightly slower in air, and slower still in water or clear glass. That's why a light ray bends as it moves from one medium to another. This phenomenon is called … Read more
Find Its Average Velocity From The Time It Is Thrown (t=0) To The Time It Reaches Its Maximum Height. Can You Help?
The instantaneous velocity at time t is the derivative of the height y, or 80 - 32t. This is 0 when t = 80/32 = 5/2 = 2.5 sec. The height at that time is y = 80 (2.5) - 16 (2.5)2 = 200 - 100 = 100 ft. The average velocity is therefore 100/2.5 … Read more
I think you have the wrong picture. It doesn't show two objects on a pivot, it shows two springs in series, and there is no D that I can find in the picture.
I believe it is because it is theoretically possible to go directly to the moon, but it would take way more fuel than is practical to carry in a rocket. The more fuel the rocket carries, the heavier the rocket is, so the less efficient each unit of fuel is. When the rocket goes into … Read more
Mg/l stands for milligrams per liter; ppm stands for parts per million (presumably by weight). Now a liter of water weighs 1 kg (killogram) by definition, which is a thousand grams. A milligram is a thousandth of a gram. Therefore, a kg is 1 million mg. So 182.5 mg/l = 182.5 mg/kg = 182.5 mg/million … Read more
I searched unitconversion.org, Wikipedia, and Google but could not find any reference to thula as a unit of mass or force or anything else that could be converted to grams. What is the context in which you saw the word used that way?
As far as I know, a Cartesian plane is not a type of plane. It is just a way of setting up a coordinate system for a plane. A plane is any 2-dimensional flat surface that extends infinitely far in all directions. There are several types of coordinate systems for a plane, but the two … Read more
