1. The Law of Superposition – the age of an object may be determined by the depth at which it is found, the deeper the object is in the Earth, the older it is.
2. Gives scientist an exact age of a rock fossil.
3. Scientist use their knowledge of the half-life of carbon and uranium isotopes to measure the age of the rock or fossil .
4. Used to determine the age of an object, when there is no record of a living thing.
5. Gives the approximate age of a fossil or artifact.
6. Used by scientist to determine the age of a fossil or artifact.
7. Estimates the order of geological or prehistoric events, but cannot be used to determine when these events have occurred.
8. Measures the decay of a rock or fossil to measure the age.
Answer:
A compressed spring
Explanation:
A compressed spring has potential energy only and no kinetic energy.
This is because kinetic energy is only possessed by particles in motion.
Energy in a compressed spring= -1/2kx² where x is the displacement.
In this equation there is no velocity so there is no kinetic energy.
Answer:
11) the difference in heat energies between products and reactants
12) enthalpy change
Explanation:
The heat of reaction is defined as that energy released or absorbed as chemical substances participate in a chemical reaction. It is a term used to denote the change in energy as reactants change into products.
Another name of heat of reaction is enthalpy of reaction. It is a state function since it depends on the initial and final states of the system.
Answer:
<h3>The answer is 7.85 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
volume = final volume of water - initial volume of water
volume = 13.91 - 12 = 1.91 mL
We have
We have the final answer as
<h3>7.85 g/mL</h3>
Hope this helps you
