What is the SI unit of luminous intensity?
Luminous intensity is one of the seven fundamental quantities in the SI system, and its unit is candela (𝑐𝑑). Lumen and lux are derived units related to light intensity, and watt measures power. For more please visit here: https://www.tiwariacademy.com/ncert-solutions/class-11/physics/chapter-1/

In the measurement of a physical quantity, random errors can be reduced by:
Random errors are minimized by taking multiple readings and averaging the results, as this method reduces the influence of outliers. For more please visit here: https://www.tiwariacademy.com/ncert-solutions/class-11/physics/chapter-1/

The refractive index of diamond is much greater than that of glass. How does a diamond cutter makes use of this fact?
A diamond cutter uses the high refractive index of diamond to create sharp, precise cuts. The greater refractive index causes light to refract more sharply, enhancing brilliance and ensuring the diamond's facets reflect light effectively for maximum sparkle.

A biconcave lens made of a transparent material of refractive index 1.25 is immersed in water of refractive index 1.33. Will the lens behave as a converging or a diverging lens ? Give reason.
The lens will behave as a converging lens. Since the refractive index of water (1.33) is higher than that of the lens material (1.25), light will bend inward, causing the biconcave lens to act as a converging lens.

Show that the angular momentum of a particle is the product of its linear momentum and the moment arm. Also show that the angular momentum is produced only by the angular component of linear momentum.
The angular momentum of a particle is fundamentally linked to its linear momentum and the concept of the moment arm, which is the perpendicular distance from the line of action of the linear momentum to the axis of rotation. Angular momentum can be defined as the product of the particle's linear momRead more
The angular momentum of a particle is fundamentally linked to its linear momentum and the concept of the moment arm, which is the perpendicular distance from the line of action of the linear momentum to the axis of rotation. Angular momentum can be defined as the product of the particle’s linear momentum and this moment arm. This relationship points out how the rotational effect of a particle is dependent, not only on its velocity but also on its distance from the axis about which it rotates.
In addition, it is worthwhile to note that angular momentum results purely from the angular component of linear momentum. The linear momentum of a particle can be divided into two components. One component is along the radius, known as the radial component, and the other is perpendicular to the radius, known as the tangential component. Since the radial component acts along the radius, it does not contribute to angular momentum because it does not produce any rotational effect. The tangential component of the linear momentum would be the one that impacts the angular momentum as it creates rotation around the axis.
Angular momentum is thus the product of the linear momentum and the moment arm, and only the tangential component of linear momentum produces the motion in an angular direction.
