Answer: The rock is 2000785 years old.
Explanation:
Expression for rate law for first order kinetics is given by:

where,
k = rate constant
t = age of sample
a = initial amount of the reactant = 800
x = amount of daughter isotope = 600
a - x = amount left after decay process = amount of parent isotope = (800-600) = 200
Half life is the amount of time taken by a radioactive material to decay to half of its original value.




The rock is 2000785 years old.

Answer:
The GPS provides the accurate location patterns
Explanation:
- Each GPS satellite consist of the multiple atomic clocks that contribute to the precise time and data to the GPS in the signal forms and this data is decoded by the serves of the GPS satellite and shows an effective synchronization and each receiver and precise time is accurate and has a variety of activity around the world.
- For an example of the Olympic committee wants all broadcast to show particular diving event at precisely the same time. Thus the receiver is set at the me time and in close synchronization. Ad us usually measured in the weeks and seconds and aero point of the night.

When the 13 United States of America declared independence from the United Kingdom in 1776, the founders were attempting to break free from the tyranny of Britain’s top-down centralized government.
But the first constitution the founders created, the Articles of Confederation, vested almost all power in individual state legislatures and practically nothing in the national government. The result—political chaos and crippling debt—almost sunk the fledgling nation before it left the harbor.
So the founders met again in Philadelphia in 1787 and drafted a new Constitution grounded in a
novel separation of state and national powers known as federalism. While the word itself doesn’t appear anywhere in the Constitution, federalism became the guiding principle to safeguard Americans against King George III-style tyranny while providing a check against rogue states.
