Electron groups could be considered as Lone pair electrons and bonded pairs of electrons.
Answer: Option D & B
<u>Explanation:</u>
The two or more electrons can be bonded by single bond, double bond, covalent bond of electrons can simply be lone pair of electrons. Unshared pair of electrons are generally termed as lone pair of electrons in an atom which are generally present in the outermost shell of atoms. Hence electron groups can be determined by bonded pairs and lone pairs of electrons.
The angular frequency in rev/s of the combination when they start rotating together is 1.8 rev/s.
Apply conservation of angular momentum:
Ii.ωi=If.ωf
⇒ 1/2mR² ×3.0=( 1/2mR²+m(2R)²/12)ωf
⇒ωf =1.8rev/s.
A scalar representation of rotation rate in physics is called angular frequency, or "". It speaks of the angular displacement per unit of time, the rate of change of a sinusoidal waveform's phase, or the rate of change of the sine function's argument. The difference between angular frequency (measured in radians per second) and frequency (measured in cycles per second, also known as Hz) is two. Instead of the letter f, the symbol for frequency in this figure is. an axis-centered rotating sphere. Points further from the axis move more quickly, fulfilling = v / r. Angular frequency (), also referred to as radial or circular frequency, calculates the amount of angular momentum per unit of time. Therefore, it is measured in degrees (or radians) per second.
