Question

A person buys 10 cords of wood and carefully stacks it in his wood shed which has a partform 16 feet long and 10 feet wide. How high does he end up staching the wood> A piece of apatite hat a hardness of 5 on the MOH scale. besides diamond, name something that would scratch the Apatite, and also something that theapatite would be able to scratch. A sample of Carbon Is found to have only l/6th of its original Carbon-14. How many half-lifes does that correspond to? Match the item on the left with the correct descriptor on the Right

Explanation / Answer

This is 4 half-lives (1/2 + 1/2 + 1/2 + 1/2 = 2):

Four half-lives:

1 ---> 1/2 ---> 1/4 ---> 1/8 ---> 1/16

f = 1/16

four half lifes for 1/64th of original carbon

match the following

1.ohm ------(f) resistance

2.farad ------(g) capacitance

3.henry -----(a )inductance

4.tesla -------(E) magnetic flux density

5.ampere

6.weber ------(c) magnetic flux

7.watt -------(D) power = V*I

8.volt -----

pressure units is pascal or Torr
