Answer:

Specific heat capacity of metal is 2.6 J/g°C.

Explanation:

Heat lost by metal = Heat gained by water

\(m_{m}\)\(c_{m}\)ΔT = \(m_{w}\)\(c_{w}\)ΔT

where: \(m_{m}\) is the mass of metal, \(c_{m}\) is the specific heat capacity of metal, ΔT  is the change in temperature of metal and \(m_{w}\) is the mass of water, \(c_{w}\) is the specific capacity of water and ΔT is the change in temperature of water.

32.8 x  \(c_{m}\) x (100.5 - 30.2) = 138.2 x 4.2 x (30.2 - 20.0)

32.8 x \(c_{m}\) x 70.3 = 138.2 x 4.2 x 10.2

\(c_{m}\) x 2305.84 = 5920.488

\(c_{m}\) = \(\frac{5920.488}{2305.84}\)

    = 2.56761

\(c_{m}\) = 2.6 J/g°C

The specific heat capacity of the metal is 2.6 J/g°C.

The specific heat capacity of the metal is 2.6 J/g°C.

We know that

Heat lost by metal = Heat gained by the water

So,

\(m_mc_m\Delta\ T = m_wc_w\Delta\ T\)

Here

\(m_m\) is the mass of metal,

\(c_m\) is the specific heat capacity of metal,

ΔT  is the change in temperature of metal

\(m_w\) is the mass of water,

\(c_w\)  is the specific capacity of water

and ΔT is the change in temperature of water.

Now

32.8 x c_m  x (100.5 - 30.2) = 138.2 x 4.2 x (30.2 - 20.0)

32.8 x c_m x 70.3 = 138.2 x 4.2 x 10.2

\(c_w\) = 2.6 J/g°C

Explanation:

Answer: The value of acceleration due to gravity, commonly denoted as "g," is the acceleration experienced by an object due to the force of gravity acting upon it.

The value of g varies from planet to planet because the strength of the gravitational force depends on the mass of the planet and its distance from the object experiencing the force.

Explanation: On Earth, the standard value of g is approximately 9.8 m/s^2. This means that an object weighing 100 grams on Earth would experience a force of approximately 9.8 newtons (N) acting upon it due to gravity.

The value of g varies slightly from planet to planet because the strength of the gravitational force depends on the mass of the planet and its distance from the object experiencing the force.

For example, the value of g on the Moon is about 1.62 m/s^2, which is about 60% of the value on Earth. The value of g on Mars is about 3.71 m/s^2, which is about 30% of the value on Earth.

The introduction of the spiny water flea into the lake is likely to have a negative effect on the balance of the native ecosystem, as the water fleas will compete with native fish for resources such as zooplankton, and may disrupt the existing food chain.

A water flea is an aquatic crustacean. Normally, it is a member of the order Cladocera, meaning it has a small body, two antennae, and a single shell (a carapace) over its back. Water fleas move by using the hair-like setae which are located on their legs. They are an important part of aquatic ecosystems as they are used as food by other aquatic organisms. They also help to clean up organic matter in water bodies, thus improving water quality.

A zooplankton is a microscopic or tiny aquatic animal, usually found in oceans or freshwater bodies. They are usually very small in size and typically feed on phytoplankton. Zooplankton are key components of aquatic food webs and are a vital part of the aquatic environment. They are also important for carbon cycling, filtering pollutant particles from the water, providing food for fish and other aquatic organisms, and providing a food source for larger predators.

Anaerobic fermentation is a metabolic process done by bacteria and eukaryotes in the absence of air to convert carbohydrates into the products like gases, alcohol, and acids.

In the absence of oxygen, bacteria and eukaryotes carry out anaerobic fermentation, a metabolic process that produces gases, alcohol, and acids from carbohydrates.

Various compounds, including acetic acid, are produced in industries using this fermentation. While there is no oxygen present during fermentation, energy can still be generated from the glucose. Yeast cells undergo fermentation, while bacteria and mammalian muscle cells also undergo some sort of fermentation.

Energy is produced from glucose through two different types of cellular respiration: aerobic fermentation and anaerobic fermentation. Anaerobic fermentation can occur without oxygen while aerobic fermentation does. The three primary types of fermentation are lactic acid fermentation, ethanol fermentation, and hydrogen and oxygen.

In September the earth will be experiencing  an equinox

Equinoxes occur between March and September. When the Sun's rays strike the equator at midday and at a 90° angle, it is considered an equinox.  It stands for the idea that day and night have equivalent lengths. The sunset and dawn are separated by 12 hours everywhere on Earth. One may observe how quickly the sunset and dawn hours shift throughout the day the farther one goes from the equator.

Whereas, solstices occur in June and December. The contrary is visible close to the solstices. For a few days, both the sunset and sunrise appear to be constant. Over the course of the year, the time of day when the sun is directly overhead where one lives also gradually changes.

The characteristic used to determine a banana's relationship to other plants is its morphology or physical characteristics.

What is morphology?

Morphology is the study of the form and structure of living organisms, including their physical and anatomical features. In biology, morphology is used to describe the appearance, shape, and size of different parts of an organism, such as its organs, tissues, cells, and even its molecules. This includes the study of external and internal structures, as well as their function, development, and evolution. Morphological characteristics are often used in the classification and identification of different species, as they can provide important clues about an organism's evolutionary history, ecological niche, and relationship to other organisms.

We assume you are referring to the scientific classification of bananas in the plant kingdom. In this case, the characteristic used to determine a banana's relationship to other plants is its morphology or physical characteristics. Bananas belong to the genus Musa, which is part of the family Musaceae.

The characteristics used to classify plants into different taxonomic groups include their structural features, such as their leaves, stems, flowers, and fruit, as well as their genetic and evolutionary relationships. These characteristics are used to group plants into increasingly broader taxonomic categories, from species to genus, family, order, class, phylum, and kingdom.

( d ) The brittle lithosphere cracks under pressure from the moving asthenosphere.

Explanation:

~ The earth's crust refers to the outer layer of the planet earth . The surface of a planet is usually formed of less dense material than the deeper layers. Only 1/3 of the earth's crust is terrestrial , the rest is covered by oceans . The thickness of the earth's crust is between 10 to 30 miles.

The earth's crust, which is the upper part of the lithosphere , is divided into two layers. The top layer is continental , which is composed of granite . While under granite is a layer of hard rock called basalt .

On a semi-liquid planet , such as Earth , the earth's surface floats on top of the liquid inner layer. The crust seems to be often divided into pieces known as tectonic plates which due to the movement of molten magma beneath it, are able to move. This is a phenomenon of continental drift theory . In addition, collisions between two tectonic plates can produce volcanoes .

If a white powder is found next to a deceased victim at a crime scene, the first test is the A. Marquis test to check for fentanyl

Fentanyl is a potent synthetic opioid that has been involved in numerous cases of drug overdoses and illicit use. The Marquis test is a common presumptive test used to detect the presence of opioids, including fentanyl. It involves adding a few drops of the Marquis reagent, which typically contains formaldehyde and sulfuric acid, to a small sample of the white powder. If fentanyl is present, it will produce a characteristic color change or reaction.

Given the potentially lethal nature of fentanyl and its widespread illicit use, it is crucial to identify its presence early on to ensure the safety of the investigators and to guide further investigation. If the initial Marquis test indicates the presence of fentanyl, additional confirmatory tests can be performed to validate the findings and gather more detailed information about the substance.

It is important for forensic scientists to exercise caution and follow proper safety protocols when dealing with unknown substances, particularly those that may pose significant health risks. Therefore, Option A is correct.
