Correct Answer: D. sedimentation

Explanation

ai. Electric potential at a point is defined as the work done in bringing a unit positive charge from infinity to that point against the electrical forces of the field.

ii. Process of Charging:

Induction: Involves redistributing charges within an uncharged body without direct contact with a charged object.

Contact: Requires direct physical contact with a charged object to transfer charges.

- Nature of Final Charge:

Induction: Results in a charge of opposite polarity to the charged object initially brought close.

Contact: Results in a charge of the same polarity as the charged object with which contact is made.

b. - Safety: Opening the circuit prevents current from flowing, which reduces the risk of electric shock. This is especially important when working with high voltages or currents.

- Conservation of battery power: If the circuit is left closed, the current will continue to flow even when no readings are being taken. This can drain the battery and shorten its lifespan.

- Accurate readings: If the circuit is left closed, the current flowing through the circuit can cause the components to heat up. This can affect the accuracy of the readings.

- Protection of equipment: If the circuit is left closed, a surge of current could flow through the circuit if there is a fault. This could damage the equipment or even cause a fire.

c. \(Z^2 = R^2 + X{_L}^2\)

\(Z^2 = R^2 + (2πf_L)^2\)

\(Z^2 = R^2 + 4π^2f^2L^2\)

\(Z^2 = 4π^2f^2L^2 + R^2\)

∴ \(Z = \sqrt{4π^2L^2f^2 + R^2}\)

ii. from the equation

\(Z^2 = 4π^2f^2L^2 + R^2\)

using y = mx + c = y = \(Z^2\), x = \(f^2\)

m = \(4π^2L^2\) = slope of the grape

m = \(\frac{ Z_2^2 - Z_1^2}{f_2^2 - f_1^2} = \frac{ 700 - 200 }{ 800 - 140 }\)

\(4π^2L^2 = \frac{ 500}{ 660}\)

\(L^2 = \frac{ 500}{ 660} \times \frac{1}{ 4π^2} =\frac{ 500}{ 660} \times \frac{1}{4 \times 10}\) ( since \(π^2\) = 10)

\(L^2 = 0.0189\)

∴ L = \(\sqrt{ 0.0189}\) = 0.138H = 138mH

Correct Answer: A).Operating System

Explanation

Windows XP is an Operating System. An Operating System is a software that manages all the hardware and software resources of a computer. It is the most important type of system software in a computer. It is responsible for managing computer resources such as memory and processing time, as well as providing users with a way to interact with the computer.

Windows XP is a version of the Windows Operating System that was released by Microsoft in 2001. It was one of the most popular versions of Windows and was widely used until it was replaced by newer versions like Windows Vista, Windows 7, Windows 8, and Windows 10.

In summary, the correct option for the question What is Windows XP? is Operating System (Option A).
