You are an archeologist digging up an ancient village and you discover a 10lb cat. A careful
analysis reveals 5 x 10-13 lbs. of carbon-14. How old is the cat, and presumably the village?

Answers

The age of the cat and presumably the village is approximately 13657 years. .

What is Half-Life?

Half-Life is the time taken for half the amount of a substance to disappear.

To determine the age of the cat fossil, the following should be noted:

The percentage of carbon in living organisms is 19.4%The mass of the cat is 10 lb.

Mass of carbon in the sample = 0.194 × 10 lb = 1.94 lb

Ratio of carbon-12 to carbon-14 = 1 : 1.35 × 10^-12

Mass of carbon-14 initially present = 1.94 × 1/1.35 × 10^-12 = 2.619 × 10^-12

Ratio of present and original mass of carbon-14 = (5 × 10-13)/2.619 × 10^-12 =

The half-life of carbon-14 = 5700 years

The ratio of the mass of carbon-14 at present and initially = 0.191

Using the half-life formula, to calculate time elapsed:

[tex]t = \frac{t_{\frac{1}{2}}ln\frac{N_t}{N_o}}{-0.693}[/tex]

Substituting the values to solve for time, t, in years

[tex]t = \frac{5700 \times \: ln(0.191) }{-0.693} = 13656.8[/tex]

Time elapsed, t = 13656.8 years.

Therefore, the age of the cat and presumably the village is approximately 13657 years.

After a radioactive atom decays, it is the same element that it was before with no measurable change in mass. Which kind of decay has occurred, and how do you know?.

Answers

Gamma decay is a radioactive decay in which there is no measurable change in mass and the element remains the same.

What happens in gamma decay?

In gamma decay, the number of protons and neutrons in the nucleus does not change, so the product of decay remain the same element..

Note that mass number is equal to the sum of the protons and neutrons and so if there is no change, the mass of the element remains the same.

Thus, gamma decay is a radioactive decay in which there is no measurable change in mass and the element remains the same.

Answers

Different isotopes of the same element emit light at slightly different wavelengths, the minimum number of slits  is mathematically given as

N=1820slits

What minimum number of slits is required to resolve these two wavelengths in second-order?

Generally, the equation for the wave is mathematically given as

[tex]d\ sin\ (\theta\ m) \ = \ m\ \lambda[/tex]

Where the chromatic resolving power (R) is defined by

[tex]R\ =\ \lambda\ / \ d \ \lambda[/tex]

R = nN,

Therefore

[tex]\lambda_1 \ = \ (656.45)(1 \ * \ 10^{-9})/1mm[/tex]

[tex]\lambda_1= 656.45*10^{-9}[/tex]

and

question -What happens to the energy of a wave if the amplitude of the wave is doubled?

Answers

The energy carried by the waves depends on the amplitude of the wave. If the amplitude is doubled then the energy gets increased by four times.

What is amplitude?

The amplitude of a wave is the distance from the center line to the trough or the crest of the wave. The energy of the wave is directly proportional to the square of the amplitude.

E  ∝ A²

So if the amplitude is doubled then E = 4. Hence, the energy gets increased quadruples times. The energy is related to the frequency and the wavelength of the wave that travels.

Therefore, the energy gets increased by four times if the amplitude is doubled.

A) 32 g
C) 16 g
D) 8.0 g
B)4.0 g

Answers

Given the remaining quantity after the given time and the half-life, the initial quantity or original mass of the sample is 32g.

Option A) is the correct answer.

What was the mass of the original sample?

Half-life is simply the amount of time it takes a given quantity to decrease to half of its initial value.

Using the expression:

[tex]N_{(t)} = N_{0}\frac{1}{2}^{\frac{t}{t_{\frac{1}{2} }} }[/tex]

Given the data in the question;

Remaining quantity Nt = 1.0gtime t = 40 daysHalf life t(1/2) = 8.07 days

[tex]N_{(t)} = N_{0}\frac{1}{2}^{\frac{t}{t_{\frac{1}{2} }} }[/tex]

[tex]1.0g = N_{0} * (0.5)^{40days/8.07days}\\\\1.0g = N_{0} * (0.5)^{4.95662949}\\\\1.0g = N_{0} * 0.0322037055\\\\N_{0} = \frac{1.0g}{0.0322037055} \\\\N_{0} = 31.05g = 32g[/tex]
