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.
Mao's policy of commune farming
<span>1959-1961 </span>
<span>The famine triggered by the "Great Leap Forward" was one of the largest man-made disasters in human history. Estimates of the number of casualties vary greatly and are difficult, if not impossible, to verify. Conservative estimates assume that from 1958 to 1961, over 14 million people died of starvation, and the number of reported births was about 23 million fewer than under normal conditions. Other authors have estimated the number of famine-related death of up to 30 million or higher

Answer:
1 : 25,000 is the largest scale.
Explanation:
1 cm represents 2 km; is not correct because this is actually the smallest of the scales presented, meaning that 1 cm on the map is equal to 200,000 cm on the ground.
1 : 50,000; is not correct because this is the second-largest scale from the options.
1 : 25,000; is correct because it is the largest scale, with 1 cm on the map representing 25,000 cm on the ground. The smaller the scale, the larger it is.
1 : 100,000; is not correct because it is the third-largest, with 1 cm on the map representing 100,000 cm on the ground.
I believe it is Sophia, or Sofia.
