Density = 3/5 = 0.6g/cm^3. Since the density is less than the density of water, which is 1, the object will float.
Temperature is measured with a thermometer
To solve this problem it is necessary to apply the concepts related to thermal linear expansion. Mathematically this concept can be expressed under the Equation:

Where,
Initial Length
Thermal Expanssion constant
Change in Lenght
Our values are given as



Replacing at our equation we have,



Therefore the expantion of the bar is 0.317mm
Answer:
Relative Dating
Explanation:
Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
The correct answer is false.
