42.875 AU is the answer.
Explanation:
Kepler's third law allows us to find the answer for the orbital radius of the comet's orbit and the relationship of the magnitudes are:
Orbital radio is a = 3.49 AU The ratio of the orbit to the cube to the period squared gives the Kepler constant.
Kepler studied the motion of bodies in the solar system creating mathematical relationships that describe their motion, Kepler's third law which is a direct application of Newton's second law to the orbit of the planets around the sun is
T² = K a³
Where T is the period of the orbit, a is the semi-major axis of the ellipse and K is a constant called Kepler's constant given by
K = \(\frac{4 \pi ^2 }{GM_s}\) = 3 10⁻¹⁹ s²/m³
Where G is the constant of gravitation universes, M_s the mass of the Sun
In this case they indicate the size of the orbit tabulated a = 3.5 AU and the period T = 6.54 years, let's reduce the two magnitudes to the international system of measurements (SI)
T = 6.54 years \(( \frac{365 d}{1yr} ) ( \frac{24h}{1 d} ) ( \frac{3600s}{1 h} )\) = 2.062 10⁸ s
Let's calculate the radius of the orbit
a = \(\sqrt[3]{\frac{ T^2 }{K} }\)
a = \(\sqrt[3]{\frac{(2.062 \ 10^8 )^2 }{3 \ 10^{-19}} }\)
a = \(\sqrt[3]{0.1417 \ 10^{36}}\)
a = 0.5214 10¹² m
Let's reduce to astronomical units, which corresponds to the distance from the Sun to the earth
a = 0.5214 10¹² m ( \(\frac{1AU}{1.496 \ 10^{11}}\) )
a = 3.49 AU
Let's observe that it is practically equal to the tabulated value.
The ratio of the orbit to the cube to the period squared gives the Kepler constant, which is practically invariant for all bodies in the solar system.
In conclusion using Kepler's third law we can find the radius of the comet's orbit and the relationship of the magnitudes are:
Orbital radio is a = 3.49 AU The ratio of the orbit to the cube to the period squared gives the Kepler constant

Why do people cook meat and eggs before they eat them? The answer has to do in part with the chemical changes that take place during cooking. Heat breaks down proteins in meat and eggs to change the chemical makeup of these foods. The resulting substances are easier for humans to digest. Similarly, batter undergoes chemical changes as it is baked and becomes a cake. These examples show that chemical changes can result in substances with different smells and colors. I strongly advise against eating raw meat, eggs or cake batter, but trust me: these examples show a change in taste as well. Not every change in the kitchen is chemical, though. Mixing flour, sugar, butter and eggs is a physical change. Cutting meat is a physical change, too.
The author of this passage would most likely agree with which of the following statements?
A
Raw meat smells better than cooked meat.
B
People usually overcook their eggs.
C
Chemical changes are more exciting than physical changes.
D

draw and describe the male reproductive system. Class 8
Answers
The male reproductive system has two parts i.e the reproductive organs and accessory glands. The main organ or male gonad is testis which is present in the scrotum.
(1) Scrotum: The scrotum is a pouch of pigmented skin arising from the lower abdominal wall. Scrotum protects the testes and acts as thermoregulator.
(2) Testes: Testes are primary sex organs that are extra-abdominal in position. There are about 200 to 300 lobules in each testis which are composed of germinal epithelial cells. Seminiferous tubules consist of spermatogonia (sperm mother cells) and nurse cells or cells of Sertoil. There are interstitial cells or cells of Leydig which secrete the hormone testosterone after puberty.
(3) Vasa efferentia: Vasa efferentia are a pair of ducts starting from the rete testis and entering in the epididymis.
(4) Epldidymis: Epididymis are paired structures showing about 6 m long highly coiled duct situated on the posterior border of each testis. It is differentiated into the following three regions. Caput epididymis which is upper wider head that receives vasa efferentia. The sperms undergo physiological maturation acquiring increased motility and fertilizing capacity. Corpus epididymis which is middle narrower body. Cauda epididymis which is a lower duct or tail. In the tail, sperms remain for short period and then enter the vas deferens.
(5) Vasa deferentia: A pair of tubular structures about 40 cm long arising from cauda epididymis are called vasa deferentia.
(6) Ejaculatory duct: Duct of vas deferens and a duct of seminal vesicle are the ejaculatory ducts. Both ejaculatory ducts open into urethra near the prostate gland. Seminal fluid containing sperms are carried by ejaculatory duct to the urethra.
(7) Urethra: The urethra has three parts, viz., prostatic urethra, membranous urethra and penile urethra. Urethra carries both urine and semen.
(8) Penis: Penis is the copulatory organ used for insemination or deposition of sperms in female genital tract. Through the length of penis passes the urethra.
Accessory sex glands:
(1) Seminal vesicles: The seminal vesicles are two small fibromuscular pouches present on the posterior side of the urinary bladder. They have seminal ducts which join with vas deferens and form ejaculatory ducts. Seminal fluids secreted by seminal vesicle which forms about 60% of the total volume of the semen.
(2) Prostate gland: It secretes prostatic fluid which is about 30% of total volume of semen. The prostatic fluid is a whitish and alkaline liquid. The prostatic secretion neutralizes the acidity of vaginal secretion.
(3) Caliper's glands (Bulbourethral-glands): Situated on either sides of membranous urethra are pea-sized Cowper's glands which secrete an alkaline viscous fluid.

A crane has a sharp and pointed beak while the duck has a flat beak.Explain why
Answers
Answer:
The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.
On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.
The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.
Give two examples of how homeostasis helps regulate the human body.
Answers
Answer:
Here are two examples of how homeostasis regulates different aspects of the body: Get homework help from firstgradeessays[at]gm ail. c om. Quality is a priority.
Body Temperature Regulation: The human body has a set temperature range (around 36-37 degrees Celsius or 98-99 degrees Fahrenheit) that needs to be maintained for optimal functioning. When the body temperature rises due to exercise or external heat, homeostatic mechanisms helps to cool the body. These mechanisms include sweating, which helps dissipate heat through evaporation. Dilation of blood vessels near the skin surface facilitates heat loss. Conversely, if body temperature drops, homeostatic responses like shivering and constriction of blood vessels occur to generate heat and conserve warmth.
Blood Glucose Regulation: Maintaining blood glucose levels within a narrow range is crucial for proper physiological functioning. After a meal, blood glucose levels increase, triggering the release of insulin from the pancreas. Insulin helps facilitate the uptake of glucose by cells, reducing blood glucose levels back to normal. On the other hand, when blood glucose levels drop (e.g., during fasting or exercise), the pancreas releases glucagon, which stimulates the liver to release stored glucose into the bloodstream. This process raises the blood glucose levels and restores homeostasis.

Answers
Just like an egg, plants need to find all the resources to grow and germinate. Some advantages of seeds are that they are more resistant, can be pollinated and allow for greater genetic variability.
What is the process of seed development?The process of seed development involves an orderly sequence of events. Among them are cell divisions, accumulation of reserves and loss of water. Seeds develop, undergo physiological rest, cryptobiosis, quiescence and dormancy.
Seeds are extremely important structures for the survival of plants in the terrestrial environment. They are responsible for protecting the embryo, in addition to ensuring the dispersion of species throughout the environment.

Which kind of sections should be ordered from the lab for
this investigation?
Answers
Answer and Explanation: In anatomy, bodies are divided by hypothetical geometric planes to describe location or direction of its structures. These planes are called Planes There are 3 reference planes:
1) Sagittal Plane divides the body into sinister and dexter (left and right) sides.
2) Coronal Plane divides into anterior and posterior portions.
3) Transverse Plane divides into superior and inferior portions.
For the anatomist, to have a section that shows the entire medial surface, should be ordered the Sagittal Plane, more especifically midsagittal (median) plane.

CAREFUL !! Most of the answers will be created by bots. However, here's an AI-free essay that will guarantee you not be accused of using ChatGPT.
We as a species have caused environment problems, like introducing invasive species to native ecosystems. Invasive species are organisms that are not originally from a particular area and can harm the environment by taking over and harming native plants and animals.
For instance, the Burmese python was introduced to the Everglades by people, and this species is not native to the area and has caused harm to the ecosystem by preying on native animals, leading to a decline in the population of species like rabbits, raccoons, and even allgators.
Humanity has to address the problem of invasive species. If nothing is done about it, they can cause irreversible harm to native ecosystems. By doing things to prevent the introduction and spread of invasive species, we can help protect our environment.
Therefore, it is our responsibility to try and solve the invasive species problem. We should work towards preventing the introduction of new invasive species and controlling the spread of existing ones.
