The angular velocity of the link is going to  be w₃₀ = -3j + 2k

This can be defined to mean the rate of change at which the angular position of a body would rotate. It is the time rate at which it known to revolve around an axis.

The angular velocity of the second link with respect to the ground is said to be w20 = 2k

That of link 3 is said to be w32 = -3j

We have to us formula of angular velocity to write the equation. This would be written as

w20 + w32

w30 = -3j + 2k

Link 2 of the mechanism shown rotates about the z-axis w.r.t. the ground (Link 1) at a constant 2rad/s. Link 3 rotates about a pin joint currently aligned with the y-axis at a constant -3rad/s. What is the angular velocity of the link

These are the following descriptions of rocks and layers.

Layers of rocks are also called strata (plural form of Latin strata), and stratigraphy is the science of strata. Stratigraphy deals with all the properties of layered rocks. We need to find out how these rocks relate to time.

Igneous rocks are formed from lava deep in the earth.

Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons.

In the oceans, place-to-place differences in water temperature and other characteristics are most prominent near the surface.

The temperature of ocean water varies by location, it has  place-to-place differences both in terms of latitude and depth, due to variations in solar radiation and due to the physical properties of water. The ocean surface temperature is the water temperature which is close to the ocean's surface.

The surface temperature of the world's oceans varies mainly with latitude. The warmest waters are generally near the equator and the coldest waters are in the Arctic and Antarctic regions.

There are four factors which are the reason behind temperature variation near the surface, they are- latitude, altitude, ocean currents, and distance from the sea.

Hence, option C is correct.

The electromagnetic spectrum, visible light occupies the band between 0.4 and 0.7 in "Micrometers"

The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies.

Electromagnetic radiation is consists of waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum.

Electromagnetic radiation is produced whenever a charged particle changes its velocity i.e., whenever it is accelerated or decelerated. The energy of the electromagnetic radiation thus produced comes from the charged particle and is therefore lost as it gets discharged.

The mass wasting event which will later devastate the same fire-affected areas is called Mudflows

Why do mudflows happen?

Mudflows occur when significant amounts of water collect to quickly erode soil on a steep slope. Mudslides happen when a lot of water builds up and quickly erodes the soil on a steep slope. As a result of heavy rain, for example, water seeps into the soil and separates the soil grains.

A muddy substance's starting point for flow is influenced by its particle size, water content, and topographical slope. In contrast to coarse sediment or a debris flow, shallower flows can transport fine-grained particles like mud or sand. A mud flow can start more easily when there is more water present (more precipitation or overland flow).

Coarser material may be swept up by a mud flow after it forms. Finer sediment and water that pools up behind the flowing front of the coarse-grained mudflow push the coarser silt that was taken up by the flow and often forms the front of a mudflow surge.

The rigid portion of earth composed of the crust and the uppermost part of the mantle is the lithosphere.

The solid and outer part of the Earth is referred to as lithosphere. The lithosphere constitutes the brittle upper portion of the mantle and the crust which is the outermost layer amongst all the layers of Earth’s structure. The lithosphere can be further divided into two categories. One is the oceanic lithosphere and the other is continental lithosphere.

Oceanic lithosphere is associated with oceanic crust. They are found in the ocean basins. Continental lithosphere is associated with the continental crust.

Gondwana moved northward during the Carboniferous, and periods of sea level rise/fall due to melting/advancing glaciers caused unique cyclic rock sequences of nonmarine and marine deposition. These are called cyclothems.

In geology, cyclothems are alternating stratigraphic sequences of marine and non-marine sediments, sometimes embedded with coal seams. Historically, the term was defined by European coal geologists working with coal pans formed during the Carboniferous and early Permian periods.

The deposit sequence has been exhaustively explored by petroleum geologists using geophysical profiles of continents and ocean basins. A common theory of basin-scale sedimentation is formalized under the name sequence stratigraphy.

Since the Carboniferous was a widespread ice age in the Southern Hemisphere, it is likely that several cyclothems formed as a result of oceanic regressions associated with the growth and collapse of ice sheets, respectively. A more common interpretation of the sequence gives rise to Milankovitch cycles.

Answer:

Water harvesting: Since the soil was eroded, they first set up water harvesting structures, such as swales, trenches, percolation tanks. These systems increased the efficiency of water use, recharged four existing borewells (which were not effective) and ensured a regular supply without taking from the reservoir.

Sapling plantation: Water harvesting is incomplete without planting. Saplings from government and private nurseries were used in the first plantation cycles. A nursery was set up to host young trees and plants which were later planted at Polam. The goal was to revive soils and life by planting diverse species.

Fencing: In an arid region, fires are common. To avoid damage, live fences were raised around the boundaries, and windbreaks such as huge teak trees were planted to brave the South wind blowing from the reservoir. Fruit trees have now fully reforested another 2 hectares acre of the farm. The fruit forest has become a new habitat for insects, animals and birds.

Regenerate through biodiversity: In the rest of the land, trees and plants have been scattered between local species, which adapt to the dry land climate, and tropical species. Although some died, diversification ensures that there is regeneration of life.

Animals: Animals playing a key role in regeneration. Chickens, bullocks and cows were integrated in the everyday activities. The chickens provide eggs and their excreta enriched compost. Bullocks are used for ploughing and sowing.

Local crops: Local crops such as millets, pigeon peas, green grams are also grown. Seasonal vegetables from the garden such as brinjals, curry leaves, cluster beans, rosella plants are used for daily consumption and will also be served to the 600 participants at the IPC.
