The option that expresses the age of tree in scientific notation with the lowest level of precision would be A. 3 X 10 to the 3rd power. As it contains the fewest number of significant figures.

Answer: 3.2\times 10^3

Step-by-step explanation:

In scientific notation, a given number is written as the product of two numbers, a coefficient and 10 raised to a power.

When written in standard form there must be one digit to the left of the decimal point in the coefficient.

N\times 10^n

N= coefficient

n= power, can be positive or negative

Precision of a number refers to the decimal position of the significant digit furthest to the right. The number with more number of significant digits is more precise.

Thus 3.2\times 10^3 is the least precise and written in scientific notation.

just olya [345]

Answer:

C) 50°

Step-by-step explanation:

m\angle BEC= 180\degree-(65\degree+65\degree)

\implies m\angle BEC= 180\degree-130\degree

\implies m\angle BEC= 50\degree

A fossilized leaf contains 18% of its normal amount of carbon 14. How old is the fossil (to the nearest year)? Use 5600 years as
Sati [7]

Answer: The age of the fossilized leaf is 13829 years.

Step-by-step explanation:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant = 100

a - x = amount left after decay process = \frac{18}{100}\times 100=18  

a) for completion of half life:  

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

t_{\frac{1}{2}}=\frac{0.693}{k}

k=\frac{0.693}{5600years}=0.00012years^{-1}

b) for finding the age

t=\frac{2.303}{0.00012}\log\frac{100}{18}  

t=13829years

The age of the fossilized leaf is 13829 years.
