How To: Prevent a car from start to test the starter

In this tutorial, we learn how to prevent the car from starting to test out the starter. The most simple way to do this is to open the hood of the car up and find the fuse locations from the owner's manual. Pull the fuses out and when you try to start the car, it will crank but it will not be able to start. You can use this to test out the battery and test the starter. When finished, remember to replace the fuses back into the car just how you removed them, then restart your car to make sure ...

How To: Determine the age of a fossil using carbon-14

If you have a fossil, you can tell how old it is by the carbon 14 dating method. This is a formula which helps you to date a fossil by its carbon. If a fossil contains 60% of its original carbon, how old is the fossil? The half life of carbon 14 is 5600 years. That means this is how long it takes for half the nuclei to decay. After 5600 years, if we start with a gram, we end up with half a gram. This rather complex formula shows you how to solve this puzzle using accepted scientific methods.
