Answer:
It is because one cannot know exactly the position of the electron within the atom.
One formulation of Heisenberg's Uncertainty Principle tells us that one cannot know simultaneously the position and momentum of the electron, so one cannot specify exactly either coordinate because the other would be infinite.
Bohr specified the most probable position of the electron at its lowest energy level in hydrogen and the product of the two would be about the Heisenberg value.
Answer:
26 m southwards.
Explanation:
From a North, East, South, West coordinate plane, moving northwards implies positive distance. While moving southwards implies negative distance.
Thus;
It moves 16 meters northward; d = 16 m
It now moves 22 meters southward; d = -22 m
It moves 12 meters northward; d = 12 m
It moves 32 meters southward; d = -32 m
Thus, total magnitude = 16 - 22 + 12 - 32 = -26 m
Thus, the object travels 26 m southwards.

Answer:
Electronegativity
Explanation:
Element: <em>An element is a substance which can not be split into simpler units by an ordinary chemical process</em>
Electronegativity: This is the power of an atom in a molecule to attract electrons. The electronegativity of an element increase across the period in the periodic table and decreases down the group. The most electronegative elements are the reactive non metals.
Examples of electronnegative element include, Oxygen, Chlorine, Fluorine, Nitrogen, sulphur etc.
Answer:
The frequency of the wave is, f = 1 Hz
Explanation:
The half-wavelength of the wave can be found from the successive compression or rarefaction.
This is equal to the successive crest or trough.
The one wavelength is the wave that completes one cycle of vibration.
Therefore, the frequency of the wavelength is defined as the number of such vibrations per second. It is given by the formula
f = 1 /T or v/λ ( v - velocity of the wave)
= 1 / 1
= 1 Hz.
The unit of frequency is Hertz.
