In our solar system  Mercury, Jupiter, Saturn , Uranus, and Neptune all also have magnetic fields. None of them have plate tectonics. Therefore any notion using the magnetic field of plate tectonics is unsound. a magnetic field is evidence of a liquid core that could possibly drive plate tectonics but it is not in itself evidence that is occurring.

Calculate the amount, in grams, of an original 300-gram sample of radioactive isotope Potassium-40 remaining after
Aleksandr [31]

Answer:

The current amount of the Potassium-40 sample is approximately 37.521 grams.

Explanation:

The amount of the sample of the radioactive isotope decays exponentially in time, the amount of mass of the sample as a function of time (m (t)), in grams, is described below:

m(t) = m_{o}\cdot e^{-\frac{t}{\tau} } (1)

Where:

m_{o} - Initial mass, in grams.

t - Time, in years.

\tau - Time constant, in years.

The time constant can be found from half life (t_{1/2}), in years, described in statement:

\tau = \frac{t_{1/2}}{\ln 2} (2)

If we know that m_{o} = 300\,g, t = 3.9\times 10^{9}\,yr and t_{1/2} = 1.3\times 10^{9}\,yr, then the current amount of the sample is:

\tau = \frac{1.3\times 10^{9}\,yr}{\ln 2}

\tau \approx 1.876\times 10^{9}\,yr

m = (300\,g)\cdot e^{-\frac{3.9\times 10^{9}\,yr}{1.876\times 10^{9}\,yr} }

m\approx  37.521\,g

The current amount of the Potassium-40 sample is approximately 37.521 grams.

IN YOUR OWN WORD
Rufina [12.5K]

Answer:

Insurance companies should have the ability to legally learn the genetic profiles of people that wish to be insured.

Explanation: The reasoning...

Insurance wise the more of a liability you are the more insurance companies might not want to provide insurance to you, and if in their own studies they should be permitted to find about any history of genetic illness, this followed by higher risks of cancer, and diabetes might make you a high-risk client. Insurance is something that is sold so that the possibilities can be dealt with. If a person has a higher risk of one of those medical possibilities that might cost the insurance company more than you pay the monthly cost. This is unsavoury for companies that work like this hence it should be in their right to allow for genetic profile background checks, funded by themselves of course.

How is continental movement measured?
yulyashka [42]

Answer:

Explanation:

Geodesy, the science of measuring the Earth's shape and positions on it, allows the measurement of plate motion directly using GPS, the Global Positioning System. This network of satellites is more stable than the Earth's surface, so when a whole continent moves somewhere at a few centimeters per year, GPS can tell.

GPS uses a system of satellites to triangulate the position of a receiver anywhere on Earth. By using a network of receivers near plate boundaries, scientists can very accurately determine how the plates behave
