Which of the following is NOT true about relative dating?
Igoryamba

Answer:

It uses fossils to help pinpoint the ages of rocks.

Explanation:

Radiocarbon  dating can not be used  to determine the age of rocks.

Carbon dating works well only for objects that are less than 50,000 years.  Most rocks are far older than that. Over time, carbon-14 decays gradually  into nitrogen. Hence, we can not really use radiocarbon dating to determine the absolute age of a rock sample since the carbon-14 in the fossils of ancient rock samples may have completely decayed.

Margarita [4]
Answer a:
<span>A 1.5 V battery, the electromagnet picked up an average of 6 paper clips, while with the 6.0 V battery, an average of 23 paper clips were picked up. Battery of 6.0V is 6.0/1.5 = 4 times stronger than battery of 1.5 V

Answer b: 
</span><span>Ratio of the number of paper clips picked up using the 6.0 V battery to the number picked up using the 1.5 V battery is = 23/6 = 3.8 </span>≈ 4. 

Answer c:
As the voltage power increase, more paper clips were picked up by electromagnet. This indicated that there is a direct relationship. Mathematically it can be expressed as: 

           Voltage Power α Number of paper clips that were picked up
