Answer:
,Mass of the Body = 10 kg.
Height = 10 m.
Acceleration due to gravity = 9.8 m/s².
Using the Formula,Potential Energy = mgh
= 10 × 9.8 × 10 = 980 J.
(b). Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant.
∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m.
∴ Kinetic Energy = 980 J.
(c). Kinetic Energy = 980 J.
Mass of the ball = 10 kg.
∵ K.E. = 1/2 × mv²
∴ 980 = 1/2 × 10 × v²
∴ v² = 980/5
⇒ v² = 196
∴ v = 14 m/s.
3. Yes - At maximum stretch the ball stops. The ball is now 2 meters plus x below the starting point where x is the stretch distance down. The total energy is all potential in the springs and gravitational and is m g (2 + x)

what would the chromosome to the right be called?
Answer:
The two identical chromosomes that result from DNA replication are referred to as sister chromatids. Sister chromatids are held together by proteins at a region of the chromosome called the centromere. Chromosomes undergo additional compaction at the beginning of mitosis.
Explanation:
Based on the position of centromere and length of chromosomal arms, the chromosomes are classified into 4 groups:
(1). Telocentric chromosomes.
(2). Acrocentric chromosomes.
(3). Sub-metacentric chromosomes.
(4). Metacentric chromosomes.

What layer of the Earth does the upper surface of the cross-section represent? Group of answer choices Inner Core Outer Core Mantle Crust
Answer:
Hello! Your answer is...
The lithosphere is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of the Earth. The crust is the layer that you live in. The Outer and Inner Cores are hotter. The temperatures of the crust vary from air temperature on top to about 1600. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.
Explanation:
Hope this helps you! I'm new, but am really smart and nice. Hope you enjoy your time on brainly!
The crust of the Earth, the uppermost layer visible in a cross-section of the planet, is halfway through at this point. The crust, which only accounts for around 1% of the Earth's total volume, is made up of igneous, metamorphic, and sedimentary rocks.
What is the upper surface of the cross-section of Earth?The rocky exterior of the Earth is known as the lithosphere. It is composed of the uppermost layer of the upper mantle and the brittle crust. You live in the crust of the earth. It is hotter in the outer and inner cores.
The crust varies in temperature from the top air temperature to roughly 1600. The Earth's tectonic plates are moved by the asthenosphere, a region of the mantle.
Therefore, Mantle Crust layer of the Earth does the upper surface of the cross-section represent.

Answer:
Medulla Oblongata
Explanation:
The primary role of the medulla is regulating our involuntary life sustaining functions such as breathing, swallowing and heart rate. As part of the brain stem, it also helps transfer neural messages to and from the brain and spinal cord. It is located at the junction of the spinal cord and brain.

Explain the role that hooved animals, such as cows, play in regenerative farming.
Answer:
I hope this helps
Explanation:
As animals move, their hooves break up the soil, compacting inedible plants and allowing nutrients and sunlight to new plants—essentially speeding up the building of soil organic matter, with crushed leaves and stalks creating a natural mulch. This better equips the soil for germinating seeds.

Describe all the tissues and cell types that are found in a leaf and describe how these individual parts work together to accomplish processes of photosynthesis.
Explanation:
While individual plant species are unique, all share a common structure: a plant body consisting of stems, roots, and leaves. They all transport water, minerals, and sugars produced through photosynthesis through the plant body in a similar manner. All plant species also respond to environmental factors, such as light, gravity, competition, temperature, and predation.
What differentiates Hela cells from other human cells?
Answer:
a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
Explanation:
The main difference between Hela cells from other human cells is that a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.
What happens when the involvement of hela takes place?The involvement of hela made to the developing field of genetics is a lot was educated about cell reproduction, DNA and mapping genetics. The hela cells prepared them ideal for use in the polio vaccine trials because they were more liable than other cultured cells.
Cancer cells such as Hela cells escape to normal cell cycle by mutations that lead to the misexpression and/or overexpression of regulatory molecules (e.g., cyclins and cyclin-dependent kinases) and faulty checkpoint control of the cell cycle.
The control of the cell cycle depends on 1-cyclins and cyclin-dependent kinases (CDKs) that regulate the cell cycle by a cascade of protein phosphorylations and 2- a group of checkpoint controls that monitor the completion of critical cellular events.
Therefore, The main difference between Hela cells from other human cells is that a normal cell contains 46 chromosomes whereas HeLa cells contain 76 to 80 (ref) total chromosomes, some of which are heavily mutated (22-25), per cell.

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.

What are the potential advantages and disadvantages of a major shift from the hard or traditional path of energy development to the soft or visionary path?
(These were the corresponding textbook pages, if needed) Please read the following from the textbook Environmental Science:
7th Edition - Chapter 17
9th Edition - Chapter 14
Answer:
Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path. Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.
