Half life means is the amount of time only half the uranium is left. So after 68.9 years only 150/2 = 75 g is left. Another 68.9 years go by and then 75/2 = 37.5 g remains. See the pattern here? then you can divide 250 by 68.9 to see how many times it's halved or just write the equation: A = 150(0.5)^(t/68.9) t is 250 years, A is amount left A = 150(0.5)^(3.63) A = 12.13 g
Answer: The information about sequential order of the event occurred in the past can be obtained by using only relative dating method.
Explanation:
Relative dating method doesn’t give information about when it happened. It provides sequential order of the events. It is the art of deciding the overall happening of past occasions (i.e., the age of an item in contrast with another), without fundamentally deciding their outright age (for example evaluated age).
In topography, shake or shallow stores, fossils and lithologies can be utilized to correspond one stratigraphic segment with another.
