How many atoms are there in a 46 cm line?
None. A line is a 1-dimensional object and so has no thickness. An atom, no matter how small, has a finite thickness and so cannot be IN a line.
How many atoms are there along a 1 cm line?
Approximately 100,000,000. This assumes the atoms are one Angstrom apart, which is actually a little closer than you can pack most of them; for larger atoms, half of that would be a reasonable number.
How many miles can a number 2 pencil write?
55Answer:Obviously the answer varies with how heavy a mark you leave and the length of the pencil. Start by assuming that a pencil is 17 cm long and has a diameter of 0.2 cm (which gives a volume of just under 0.55 cm3. If you just touch the paper so the line is 1 layer of carbon atoms thick (about 1 nm) and the full 0,2 cm wide the line would be somewhat under 300 km (180 mi) long. Application of some skill in twisting the pencil so the line is thinner could double or triple the line length.
How many nanometers are in a 2 centimeter line?
20,000,000 nm Algebraic Steps / Dimensional Analysis 2 cm*10000000 nm 1 cm=20,000,000 nm
When a pipe has an inner diameter 10 Cm and a wall thickness of 1 Cm find its outer diameter?
First, think about what a diameter of a circle is. It is a line drawn through the middle of a circle from one side to the other. Is a pipe shaped like a circle? Yes, so you can use diameters of a circle to figure this out. Second, draw a circle like the inside of the pipe. Draw a straight line through the middle from one side to the other. Write 10 cm above it. Third draw a circle around the first circle. Draw a line to one end if the first line. Write 1 cm above it. Fourth, do the same on the other end of the first inside line and write 1 cm above it. You should have a line that goes through the middle and all the way to the outside circle. Now, look at what you have: 1 cm on the outside + 10 cm on the inside + 1 cm again on the other outside. If this seems tricky run your finger along the line to see how it works. What do you have? 1 cm + 10 cm + 1 cm = 12 cm. 12 cm is the answer.
