Answer:
Explanation:
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms. A common source of ionizing radiation is radioactive materials that emit α, β, or γ radiation, consisting of helium nuclei, electrons or positrons, and photons, respectively. Other sources include X-rays from medical radiography examinations and muons, mesons, positrons, neutrons and other particles that constitute the secondary cosmic rays that are produced after primary cosmic rays interact with Earth's atmosphere.
Answer:
B. The same as that for container A
Explanation:
To calculate the average Kinetic Energy per molecule,
Where is the average kinetic energy per molecule and is the Boltzmann constant
From the above equation it is seen that only depends on the temperature of the gas
And since the temperatures of both gases are equal, their average kinetic energy per molecule is the same
If you will be rinsing your regulator after removing it from the cylinder, you must make sure that the dust cap is firmly in place.
<h3>What is Dust cap?</h3>
A dust cap is a gently curved dome mounted either in concave or convex orientation over the central hole of most loudspeaker diaphragms.
Thus, if you will be rinsing your regulator after removing it from the cylinder, you must make sure that the dust cap is firmly in place.

Answer:
It corresponds to a distance of 100 parsecs away from Earth.
Explanation:
The angle due to the change in position of a nearby object against the background stars it is known as parallax.
It is defined in a analytic way as it follows:
Where d is the distance to the star.
(1)
Equation (1) can be rewritten in terms of d:
(2)
Equation (2) represents the distance in a unit known as parsec (pc).
The parallax angle can be used to find out the distance by means of triangulation. Making a triangle between the nearby star, the Sun and the Earth (as is shown in the image below), knowing that the distance between the Earth and the Sun (150000000 Km), is defined as 1 astronomical unit (1AU).
For the case of ():
Hence, it corresponds to a distance of 100 parsecs away from Earth.
<em>Summary:</em>
Notice how a small parallax angle means that the object is farther away.
Key terms:
Parsec: Parallax of arc second
Answer:
Explanation:
The power is related to the energy by
where
P is the power
E is the energy
t is the time elapsed
The power of this nuclear power planet is
The time we are considering is 1 day, which is
So we can re-arrange the previous equation to find the energy produced by the power plant in one day:
