Explanation

The SI unit of magnetic flux is Weber (Wb)

The Weber is commonly expressed in Volt-seconds

And a flux density of one Wb/m2 (one Weber per square meter) is one Tesla (T)

Explanation

The frequency of AC (Alternating Current) supply in Pakistan is typically 50 Hertz (Hz).

AC electricity alternates back and forth in a direction 50 times per second

Explanation

The poet hears thirsty leaves drinking rainwater and sharing this blessing with the poor leaves beneath.

Explanation

In pair production, several quantities are conserved

Let's evaluate each option:

- Charge:

A charge is conserved in pair production, as the total charge before and after the interaction remains the same

Due to the opposite but equal charges of the electron and positron.

- Energy:

Energy is conserved in pair production, with the total energy before the interaction equal to the sum of the energies of the electron and positron after the interaction.

- Linear Momentum:

Linear momentum is conserved in pair production, with the total momentum before the interaction equal to the sum of the momenta of the particles involved.

Explanation

A command-line interface is used by DOS systems.

By typing a program's filename at the command prompt, a program can be launched.

Explanation

When the velocity-time graph is a straight line parallel to the time axis then its acceleration is zero.

This is because velocity is constant w.r.t time ie., the change in velocity is zero.

Hence, the acceleration is also zero.

Explanation

In C language, printf() function is used to print formatted output to the standard output stdout (which is generally the console screen).

The printf function is a part of the C standard library and it can allow formatting the output in numerous ways.
