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.

I Googled your question and the first link it gave me was your question! The second is www.flipkart.com. At first it seemed to be what you asked for, but it is not a free download. I don't seem to be able to cancel my answer at this point, so I apologize. It … Read more

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

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
