All of these statements about flux are true, except for the last one - <span>When turning a surface inside of an electric field, the maximum flux is achieved if the electric field vector and the surface vector are perpendicular.
These vectors don't have to be perpendicular, which is why this statement is incorrect, whereas the rest of them are true. </span>
Answer:
Explanation:
Answer:
Explanation:
The half life is the time taken for half of a radioactive substance to disintegrate.
The shorter the half life, the larger the decay constant and the faster the decay process.
For a very large half life, it would take a very long time for the radioactive nuclide to decay to half.
With each half life reached, a new set of daughter cell is formed. Atoms that have short half life would decay rapidly. Every radionuclide has its own characteristic half-life.
If the number of half-lives increases, then the number of radioactive atoms decreases, because approximately half of the atoms' nuclei decay with each half-life. With this observation, we can hypothesise and conduct experiment to support the assertion that as the number of half-lives increases then the number of radioactive atoms decreases.
We know that density = Mass/Volume
Volume = Mass/density
Here mass = 7.65 g
density = 12.6 g/ml
So volume 7.65/12.6=0.607 ml =
Volume of cube , where a is the edge length
In this case
So the length of the side of a cube having a density of 12.6 g/ml and a mass of 7.65 g is 0.848 cm.
Given
The speed of light through a medium is
To find
The type of material
Explanation
The velocity through a medium is given by
where c is the speed of light in .
n is the refractive index of the material
Thus,
Thus the refractive index is 2.419
We know diamond has a refractive index of 2.417-2.419
Conclusion
The material is diamond
The answer is the Goldilocks Zone.
The Goldilocks zone refers to a zone around the star that is habitable. This means that it is not too hot and not too cold.
The Kuiper belt is located beyond Neptune. The Oort cloud is even further out in the solar system, past Pluto. The asteroid belt is located in between the orbit of Mars and Jupiter.
