Answer:
sound and radio waves are completely different phenomena.
Explanation:
Given the relation that 1 light year = 9.46 trillion kilometers, and the distance from Epsilon Eridani to Earth which is 10.5 light years, we can solve for the distance between the star and Earth in light years by multiplying both values together. This is shown below
Dsitance (in trillion km) = 9.46 trillion km * (10.5) = 99.33 trillion kilometers
When we form a right triangle connecting the edge of the knife to the center of the circle and the center of the knife to the center of the circle, the radius of the circle becomes the hypotenuse. Using the trigonometric function,
sin 60° = opposite / hypotenuse = 4 / hypotenuse
The value of the hypotenuse is 4.62 inches. Then, the diameter is twice this value which is 9.24 inches.
The correct answer is D.
A nucleon<span> is one of either of the two types of subatomic particles (neutrons and protons) which are located in the nucleus of atoms.

The total number of nucleon in the nucleus of an atom gives you an idea about the mass of that atom. In fact, one may refer mass number as nucleon number.
Simply put, nucleons are the particles that make nucleus of an atom and are held up together inside the nucleus due to nuclear force.
