Why spin angular velocity of a star is greatly increased when it collapses under gravitational pull and becomes a neutron star?

Answer: While collapsing under gravitational pull, the size of the star decreases. Therefore, its moment of inertia decreases. As the angular momentum (L=I⍵) is conserved and I decreases, the spin angular velocity ⍵ is greatly increased.

Derivation Of The Expression For The Impedance Of A Series LCR Circuit

What Is Impedance? Impedance is defined as a combination of resistance and reactance. It is basically an obstruction to the flow of electrons in an electric circuit. Z is the symbol used for describing the impedance. The unit of impedance is ohm. The other way of defining impedance in terms of the phasor is that it is the ratio of the phasor voltage across the element to the phasor current through the element. What is LCR Circuit? The LCR circuit is defined as the circuit that consists of a resistor R, an inductor L, and a capacitor C. These three electrical components are either connected in series or in parallel. LCR circuit is also known as RLC circuit and this circuit gets its name from the symbols of the main electronic components that are used. The other names of the LCR circuit are resonant circuit and tuned circuit. Derivation Of The Expression For The Impedance Of A Series LCR Circuit In the below circuit diagram, let R, L and C be the resistance, inductance,...

Define Simple harmonic motion (S.H.M). Show that the bob of a simple pendulum may move with simple harmonic motion and find its time period.

Answer: A Simple Harmonic Motion , or SHM, is defined as a motion in which the restoring force is directly proportional to the displacement of the body from its mean position. The direction of this restoring force is always towards the mean position. The acceleration of a particle executing simple harmonic motion is given by a(t) = -ω 2 x(t). Here, ω is the angular velocity of the particle.
