The expression represents the perimeter, in centimeters, of the rectangle C. 2s+24r.

The fringe formula for a rectangle states that, in which P represents perimeter, L represents duration, and W represents width. while you are given the scale of a rectangular form, you can genuinely plug in the values of L and W into the system so as to resolve for the perimeter.

Perimeter = 2 ( length + width)

Where,

   Width = (5r+8s)

   Length = (7r-7s)

substituting into the formula:-

Perimeter = 2 { (5r+8s)+ (7r−7s) }

Perimeter = 2 { 5r + 7r + 8s - 7s }

Perimeter = 2 { 12r + s}

Expand bracket

Perimeter = 24r + 2s

Explanation:

Answer:

The velocity of the sound wave is 540 meters per second.

Explanation:

The sound is a consequence of mechanic waves, the velocity of a mechanic wave (\(v\)), in meters per second, is determined by following formula:

\(v = \lambda\cdot f\) (1)

Where:

\(\lambda\) - Wavelength, in meters.

\(\lambda\) - Frequency, in hertz.

If we know that \(f = 2700\,hz\) and \(\lambda = 0.20\,m\), then the velocity of the sound wave is:

\(v = \lambda\cdot f\)

\(v = 540\,\frac{m}{s}\)

The velocity of the sound wave is 540 meters per second.

Answer:

A shadow is formed by opaque bodies.

Explanation:

What is a shadow?

A shadow is a dark, two-dimensional shape formed on a nearby surface when an opaque body is placed in the path of light emitted by a source.

What are opaque bodies?

Objects that do not allow light rays to pass through them are known as opaque bodies. In other words, opaque bodies obstruct the path of incident light rays.

Why is a shadow formed?

A shadow is a dark two - dimensional cast of an opaque object placed in the path of light, on a nearby surface. Since the body obstructs the passage of light rays following that path and either deflects or absorbs them, so no light ray reaches the surface in the region covered by the projection of the body on that surface.

Hence the area appears dark and assumes a shape exactly identical to the shape of the opaque body.

The correct response is  c. geosphere. The geosphere is made up of every rock on Earth, from the melting rock beneath the crust to the massive, age-old mountains to the sand grains on the seashore. The biosphere, a global ecosystem that includes all life on Earth, has a home in both the geosphere and the hydrosphere.

Different definitions of the geosphere have conflicting uses. It can be used to refer to the atmosphere, lithosphere, hydrosphere, and cryosphere as a whole. Different mass and/or energy flows can be exchanged between the various geosphere collectives (the measurable amount of change). The balance of the various geosphere spheres is impacted by the exchange of these fluxes. As an illustration, consider how the soil functions as both a source of flux exchange and as a component of the biosphere. According to the Physical and Meteorological lectures, the phrase was used to refer to four spherical natural locations that were concentrically nested around the center of the Earth. They were thought to be able to explain how Earth, Water, Air, and Fire moved on Earth. The term "geosphere" is used to describe the solid portions of the Earth in contemporary texts and in Earth system science, together with the terms "atmosphere," "hydrosphere," and "biosphere," to characterize the Earth's processes (the interaction of these systems with the magnetosphere is sometimes listed). In that context, the term "lithosphere" may occasionally be used in place of "geosphere" or "solid Earth." However, the term "lithosphere" only refers to the Earth's solid surface layers (oceanic and continental crustal rocks and uppermost mantle).

"Basaltic lava is thicker than andesitic lava", is not true about andesite and basalt. Hence the correct answer is option A.

While andesitic lava has a high viscosity, basaltic lava is less viscous and more liquid. Andesitic lava has a high silica content, which contributes to its high viscosity; basaltic lava has a low silica content, which accounts for its lower viscosity.

Andesitic lava arises at destructive plate boundaries from the melting crust, whereas basaltic lava forms at constructive plate boundaries and hotspots from heated mantle material. While basaltic eruptions are generally stationary and produce lava flows and modest eruptions, andesitic eruptions are frequently explosive.

There are a lot of earthquakes and volcanoes in the Ring of Fire because the tectonic plates in the area are shifting so dramatically.

In convergent boundaries known as subduction zones, plates overlap around a large portion of the Ring of Fire. In other words, the plate above pushes the plate below, or subducts it. The circum-Pacific Ring of Fire, where the Pacific Plate collides with numerous neighbouring tectonic plates, is one such region.

The world's most seismically and volcanically active region is the Ring of Fire. The tectonic plates encompassed by the Ring of Fire include the enormous Pacific Plate as well as the smaller Philippine, Juan de Fuca, Cocos, and Nazca plates. Several of these plates are being subducted under the continental plates they border.

The Hawthorne effect, named after a series of studies conducted at the Western Electric Hawthorne Works in Chicago, took place at the Hawthorne Works facility between 1924 and 1932. The studies were originally intended to investigate the relationship between lighting conditions and worker productivity. However, the researchers inadvertently discovered that the presence of observers and the attention given to the workers during the study had a significant impact on their performance.

The Hawthorne Works was a large manufacturing plant owned by Western Electric, a subsidiary of AT&T. It employed thousands of workers and was involved in the production of various electrical equipment, including telephone equipment and components. The studies were conducted by a team of researchers from Harvard University and the Western Electric Company, led by Elton Mayo, a social scientist.

The specific location of the Hawthorne Works was in Cicero, a suburb of Chicago, Illinois, United States. The studies involved various experiments that manipulated factors such as lighting conditions, rest breaks, and working hours to assess their impact on worker productivity. However, it was during these experiments that the researchers noticed a consistent increase in productivity regardless of the changes made, leading them to attribute the effect to the workers' awareness of being observed and the significance placed on their participation in the study.

The Hawthorne studies became significant in the field of social sciences, particularly in industrial and organizational psychology, as they highlighted the influence of social and psychological factors on workplace behavior. The studies' findings challenged the traditional understanding of productivity solely based on physical conditions and opened up new avenues for understanding human behavior in organizational settings.

The two ways to calculate damages under implied warranty of habitability are (1) actual damages and (2) constructive eviction.

Under the implied warranty of habitability, landlords are required to maintain rental properties in a habitable condition that is safe, sanitary, and fit for human habitation. If the landlord breaches this warranty, the tenant may be entitled to damages. The two ways to calculate damages are:

Actual damages: This compensates the tenant for any harm or injury suffered as a result of the breach of the warranty. For example, if the landlord fails to repair a leaking roof, and the tenant's personal property is damaged as a result, the tenant may be entitled to damages to cover the cost of repairing or replacing the damaged property.

Constructive eviction: This occurs when the landlord's breach of the warranty makes the rental property uninhabitable or substantially interferes with the tenant's use and enjoyment of the property. In such cases, the tenant may terminate the lease and recover any rent paid during the period of the breach.

For example, if the landlord fails to provide heat during the winter, the tenant may be entitled to terminate the lease and recover any rent paid during the winter months.

The cluster of small hills in the northern portion of the map illustrates a landform known as a "drumlin."

Drumlins are elongated hills that are formed by glacial action. They have a characteristic teardrop shape, with a gentle slope on the upstream side and a steep slope on the downstream side. These landforms are created when glaciers move over an area, picking up and depositing material. The material is molded and reshaped by the movement of the glacier, resulting in the formation of drumlins. They are typically found in regions that were covered by glaciers during past ice ages.

Based on the conceptual models of warm and cold fronts over the continental US as presented in chapter 11, weather can be observed before, during, and after the passage of either a warm front or a cold front.

The weather observed at a particular location before, during, and/or after passage of either a warm front or cold front can be categorized as follows:

Before a warm front: Before the warm front arrives, weather can be observed as the sky is often overcast and can get progressively thicker as the front approaches. Temperatures rise steadily, as do the dew points, which usually occur several hours before the front arrives. When a warm front approaches, the wind frequently becomes light and variable.

After a warm front: After the warm front passes, skies can clear rapidly and temperatures can warm up significantly. The barometric pressure increases as well.During a cold front: During a cold front passage, the temperature drops quickly, and the wind frequently becomes gusty and variable. The precipitation can often be heavy and of short duration. The sky, on the other hand, is typically broken or overcast and sometimes stormy.

After a cold front: After the cold front passes, the precipitation ceases, and the wind frequently changes direction. The temperatures decrease, and the sky usually clears quickly. Barometric pressure rises rapidly in response to the front’s passage. Therefore, based on the conceptual models of warm and cold fronts over the continental US as presented in chapter 11, weather can be observed before, during, and after the passage of either a warm front or a cold front.

The contour lines cross one another in a cliff because they indicate the change in elevation of the landmass. Contour lines are the lines that connect points of equal elevation on a topographic map. They are used to visualize the 3-dimensional surface of the Earth in 2 dimensions by depicting the height of the land above sea level. Contour lines cross one another in a cliff as the elevation changes rapidly along the cliff face. The closer the contour lines are to one another, the steeper the slope of the cliff is. When contour lines cross one another, it indicates a vertical cliff or overhang where the elevation changes abruptly.

The “great ocean conveyor belt” is an ocean current that plays a vital role in keeping our planet's atmosphere liveable. This current works by transferring heat around the globe, regulating temperatures and making life possible.

The ocean conveyor belt is driven by differences in water density, which are caused mainly by two factors: temperature and salinity. Colder and saltier water is denser and sinks to the bottom, while warmer, less salty water rises to the surface. This cycle of warm and cold water currents creates a continuous loop of ocean conveyor belt motion.

By moving heat energy around the globe and regulating temperatures, the ocean conveyor belt helps maintain a livable climate. This ocean current is an essential part of keeping our planet liveable, and highlights the importance of protecting our oceans and their inhabitants.
