Answer 1

Answer:

1. Phase angle (θ) refers to the angular component of the complex number representation of the function. This notation is frequently used to represent an electrical impedance . In this case, the phase angle is the phase difference between the voltage applied to the impedance and the current driven through it.
2. The angle which specifies the displacement as well as the direction of motion of the point executing SHM is called phase angle. Thus, it indicates the state of motion of the vibrating the simple harmonic Oscillor is.
3. If the length is doubled, the period will increase by a factor of √2 . Doubling the mass of the bob will half the period.
4. The mass continues in SHM that has an amplitude A and a period T. The object's maximum speed occurs as it passes through equilibrium
5. The restoring force must be proportional to the displacement and act opposite to the direction of motion with no drag forces or friction. The frequency of oscillation does not depend on the amplitude.
6. In physics, energy is the quantitative property that must be transferred to a body or physical system to perform work on the body, or to heat it. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement in the International System of Units (SI) of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of one metre against a force of one newton.
