Step 1: Identify which of the given materials is an industrial waste product.
- Lime: A naturally occurring material used in construction, but not a waste product.
- Sand: A naturally occurring granular material, not an industrial byproduct.
- Brick: Manufactured from clay and other materials but not classified as industrial waste.
- Fly Ash: A fine powder byproduct from coal combustion in thermal power plants, widely used in construction.
Step 2: Fly ash is utilized in the production of cement, concrete, and bricks due to its binding properties and environmental benefits.
Thus, the correct answer is option B Fly Ash.
Mantri Mandir -- Where is it located?
What material is commonly used for doors and windows?
What architectural structure balances the bridge weight? (Refer to the image of a truss bridge)
Identify the location shown in the picture:
Figure 1 shows the configuration of main scale and Vernier scale before measurement. Fig. 2 shows the configuration corresponding to the measurement of diameter $ D $ of a tube. The measured value of $ D $ is:
The center of a disk of radius $ r $ and mass $ m $ is attached to a spring of spring constant $ k $, inside a ring of radius $ R>r $ as shown in the figure. The other end of the spring is attached on the periphery of the ring. Both the ring and the disk are in the same vertical plane. The disk can only roll along the inside periphery of the ring, without slipping. The spring can only be stretched or compressed along the periphery of the ring, following Hooke’s law. In equilibrium, the disk is at the bottom of the ring. Assuming small displacement of the disc, the time period of oscillation of center of mass of the disk is written as $ T = \frac{2\pi}{\omega} $. The correct expression for $ \omega $ is ( $ g $ is the acceleration due to gravity):
