Answer:
24555 years
Explanation:
Data provided in the question:
Half life of carbon 14 = 5700 years
carbon present in the dead man = 5% of the original amount of carbon 14
Now,
let the initial Amount of carbon be 'A'
Therefore,
after half life
Amount of carbon = 
Thus,
= 
here,
k is the decay constant
t is the time = 5700 years
therefore,
1 = 
or
0.5 = 
taking natural log both the sides
-0.69314 = 5700k
or
k = - 0.000122
therefore,
for dead man Amount of carbon = 5% of A = 0.05A
thus,
0.05A = 
or
0.05 = 
taking natural log both the sides
we get
-2.995 = - 0.000122 × t
or
t = 24555.18 ≈ 24555 years
Answer:
A. because research not show yet about pheromones for wolves
Answer:roots grow into the ground
Explanation:
it is a coordinated process of differential growth by a plant in response to gravity pulling on it. It also occurs in fungi. Gravity can be either "artificial gravity" or natural gravity. It is a general feature of all higher and many lower plants as well as other
Answer:
particulate hypothesis of inheritance
Explanation:
This states that the inheritable factors retain their identity generation after generation.
The event was volcanic eruption.
The second largest volcanic eruption took place in June 1991. The volcanic eruption took place in the Mount Pinatubo (a chain of volcanoes along the Luzon arc) on the island of Luzon in the Philippines. After the millions of tons of sulfur dioxide were discharged into the atmosphere, resulting in a decrease in the temperature worldwide over the next few year.
