A wooden object from the site of an ancient temple has a carbon-14 activity of 10 counts/min compared with a reference piece of

wood cut today that has an activity of 40 counts/min. If the half-life for carbon-14 is 5730 y, what is the age of the ancient wood object?

Answer:

Age of the ancient wood object is 11460 years.

Explanation:

We know that half-life for carbon-14 is 5730 years. That means the activity of the sample will decrease to half every 5730 years.

Now we construct the following table:

activity (counts/min)        age of the wooden object

      40                                                  0

      20                                               5730

      10                                                11460

Particles that are smaller and have ____ generally dissolve faster.(1 point)
saw5 [17]

Answer:

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

What is Gay lussac's law​
k0ka [10]

Explanation:

Gay-Lussac's law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas when the volume is kept constant. Mathematically, it can be written as: {\displaystyle {\frac {P}{T}}=k}. It is a special case of the ideal gas law.
