لینز کا قانون _____ کی وضاحت کرسکتا ہے؟
- Only two of the three types of magnetism
- Ferromagnetism only
- Diamagnetism only
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Lenz’s Law states that the induced current opposes the change that produces it.
When a magnetic field is applied, induced currents in atoms oppose the applied field.
This opposing effect explains the behavior of diamagnetic materials.
Paramagnetism and ferromagnetism are explained mainly by electron spin and magnetic domains, not Lenz’s law.
Therefore, Lenz’s Law helps explain diamagnetism only.

- Torque is measured in candela
- Torque and candela are unrelated physical quantities.
- Torque is directly proportional to candela.
- Torque is inversely proportional to candela.
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Torque and candela measure completely different physical quantities.
Torque (τ) is the rotational equivalent of force: τ = Force × Lever arm.
Its SI unit is Newton-meter (N·m).
Candela (cd) is the SI unit of luminous intensity (brightness of light).

پی قسم کا مواد کس پر مشتمل ہوتا ہے؟
- Intrinsic 3D crystals of silicon
- Intrinsic 4D crystals of silicon
- Intrinsic 2D crystals of silicon
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- P-type semiconductor is made by doping pure silicon.
- Trivalent impurities (like boron, aluminum, gallium) are added.
- These atoms have 3 valence electrons.
- This creates holes (positive charge carriers) in the crystal.
