Half an inch equals exact 1.27 centimeters.
Would a cell survive if it were to cut in half?
If a cell were to be artificially cut in half it would not survive. Cutting a cell would mean breaking the cell membrane. A typical cell cannot survive without the membrane. However, in nature, there is a process called cell division where there is a natural division of cells to half its volume, thus creating two cells from the parent cell. This type of division results in living cells.

How are radioactive isotopes used determine the absolute age of igneous rock?
Answer : When the isotopes decay, scientists can find out how old the rock is depending on the radioactive isotope's half-life. Explanation: Radioactive isotopes are unstable and will decay. For example, when humans die carbon-14 decays. The isotopes will decay into a stable isotope over time. Scientists can tell how old the rock was from looking at the radioactive isotope's half-life, which tells them how long it would take for there to be half the radioactive isotope and half the stable isotope. At the next half-life there will be 25% of the radioactive isotope and 75% of the stable isotope. At the next half life there will be 12.5% radioactive and 87.5% stable. Example: Carbon-14 is a radioactive isotope with a half life of 5,730 years. How old would carbon-14 be when there is 75% carbon-14 in the rock? 75% is half of the time before the half-life, so it would be 2,365 years. Hope this helps. Half life helps scientists find how much the isotope has decayed and the age of the rock.
Is breaking a pencil in half a chemical change?
Nope - it's a physical change. The chemical composition of the pencil is still the same !

If you eat a piece of led will you die?
Yes you can die from eating led but, if it was a number 3 pencil that someone ate its graphite and you can only die from lead if you eat a lot of it for example half of a pencil or a whole pencil.
How long is a mechanical pencil eraser in inches?
A mechanical pencil or propelling pencil is a pencil with a replaceable and mechanically extendable pencil lead.The eraser is fitted on top of the pencil at the opposite end to the lead.The maximum length of the eraser would be no more than half an inch when new.
Is the width of a pencil a centimeter?
No, about half that.
If you have a half dollar and pencil and some water which of these have the greatest density?
The half dollar has the greatest density because it will sink, the water has more density than the pencil because the pencil will float.

How many lines does a pencil truly have so that it is equal?
how many lines of symmetry does a pencil have ? the answer is one if you hold up a pencil there is only one way or it would be uneven any way else the first way is if you are like-laying it down and go across the pencil but not in half
What is a example of 1 cm?
About half, or one third, the width of a typical finger. The thickness of a pencil or pen might be a little less than a cm.
