To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
The net force acting on the car is 3 which slows the car down.
<span>This reduction happens because potential energy transforms to "thermal energy" and "sound energy"

Answer:
h = 3.10 m
Explanation:
As we know that after each bounce it will lose its 11% of energy
So remaining energy after each bounce is 89%
so let say its initial energy is E
so after first bounce the energy is

after 2nd bounce the energy is

After third bounce the energy is

here initial energy is given as

now let say final height is "h" so after third bounce the energy is given as

now from above equation we have
