Answer:
a state in which opposing forces or influences are balanced.
Explanation:
The answer is an ancient solar system
The wavelength of the radio wave is 0.303 m.
<h3>
Wavelength</h3>
The wavelength of the wave is the distance traveled by the wave.
c = fλ
where;
- c is speed of light = 3 x 10⁷ m/s
- f is frequency
- λ is wavelength
λ = c/f
λ = (3 x 10⁷ ) / (99 x 10⁶)
λ = 0.303 m
Thus, the wavelength of the radio wave is 0.303 m.

Velocity. Velocity is physical vector quantity; both magnitude and direction are needed to define it. Magnitude is this case meaning speed.
In rutherford experiment he bombarded highly energetic alpha particles towards the gold foil
He observed that most of the alpha particles pass through the foil without any deviation while very few of the alpha particles are there which reflect back to its own path
while very less in number was there which were deflected from there path
so he concluded that the positive charge of atom is concentrated inside the nucleus and it is small space in tom and electrons are surrounded them
so correct answer would be
4. In an atom, most of the mass and the positive charge are located in a small core within the atom called the nucleus.
