Answer:
t = 39.04 1010 year
Explanation:
This is a nuclear disintegration exercise that is governed by the equation.
N = N0 e (-lam t)
The average life time is related to nuclear activity
T ½ = ln 2 / lam
Let's use these two equations for exercise, let's start by finding nuclear activity
Lam = ln 2 / T ½
Lam = ln 2 / 4.9 10 10
Lam = 0.14146 10-10 y-1
They tell us that the relationship atoms
No / N = 0.0040
Let's look
No / N = 1/0040
N/No = 250
Let's calculate the time
(-lam t) = ln (N / No)
, t = - 1 / lam ln (n / No)
t = - 1 / 0.14146 10-10 ln (250)
t = 39.04 1010 year
The answer would probably be B.
The 2 spots after the decimal still counts toward the total the figures
Physical science is the study of matter and energy, and the relationship between matter and energy.
E. The study of matter and energy, and the relationship between matter and energy
<u>Explanation:</u>
The study of issue and vitality and the associations between physicists concentrate such subjects as gravity, light, and time. Albert Einstein, a well known physicist, built up the Theory of Relativity.
Material science is the investigation of issue and vitality at all scales—from the littlest particles of the issue to the whole universe.
A geologist has practical experience throughout the entire existence of Earth. A sea-life scholar contemplates sea plants and creatures. A physicist ponders matter, vitality, and how they are connected.
There are three primary parts of science: physical science, Earth science, and life science. Physical science is the investigation of lifeless common items and the laws that administer them. It incorporates material science, science, and cosmology.
