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:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant = 100
a - x = amount left after decay process =
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.
b) for finding the age
The age of the fossilized leaf is 13829 years.
The answer is 2.
This is because the line crosses the x axis in 2 different places.
Hope this helps!

Answer: A wheel on the outer rail travel 12.57 ft more than a wheel on the inner rail of the track.
Step-by-step explanation:
Since we have given that
Radius of inner circle = 57 ft
As we know the formula for "Circumference of circle":

Since we have also mentioned that there is 2 feet wide circular track for a camera dolly.
So, Radius of outer circle will be given as

So, Distance = Circumference is given by

Hence, Difference between the outer rail travel than a wheel on the inner rail travel is given by

Therefore, A wheel on the outer rail travel 12.57 ft more than a wheel on the inner rail of the track.
Hi,
Answer:
48 cm
Step-by-step explanation:
14 + x = 62
62 - 14 = 48
x = 48 cm
Have a good one!
