Two astronauts, one of mass 55 kg and the other of mass 85 kg, are initially at rest together in outer space. They then push each other apart. How far apart are they when the lighter astronaut has moves 12 m?.
As a result, the heavier astronaut moved 19 meters whilst the lighter astronaut moved 12 meters.
Calculation:Mass of the first astronaut, m1 = 55 kg
Mass of the second astronaut, m2 = 85 kg
Distance moved by the first astronaut, d1 = 12 m
d2 = distance traveled by the second astronaut.
using the law of conservation of momentum, we can say
m1d1 = m2d2
So that, d2 = m1d1 / m2
d2 = (55 * 12) / 85
d2 = 660 / 85
d2 = 7 m
If we then account for the 12 m that the first astronaut traveled. According to our calculations, the second astronaut traveled a total distance of 7 + 12 = 19 m.
When an astronaut is in space, does their weight change?Astronauts are basically weightless in space since there is no gravity pulling them down. Investigating the distinction between mass and weight is crucial. Astronauts' bodies remain the same shape and size even though they may not weigh anything and can move around freely in space.
Are astronauts heavier in space or on Earth?The astronaut's mass won't differ between the Earth and the Moon. Although weight of a person varies depending on where they are on the earth, mass is a fixed figure. Weight is the force of gravity acting downward on a person or any other body.

In the hydrosphere, increases in temperature cause ice to melt. The liquid water become less reflective than the ice, which
leads to an increase in temperature. What type of feedback loop is this, and why?
Answer: positive feedback loop
Explanation:
A positive feedback loop is a process in which an initial change in a system leads to a further change in the same direction, amplifying the initial change. In this case, an increase in temperature causes ice to melt which leads to an increase in temperature because the liquid water is less reflective than the ice, which means that the water absorbs more heat from the sun leading to further increase in temperature. This process amplifies the initial increase in temperature, creating a self-reinforcing cycle.
This is a positive feedback loop because it amplifies the initial warming rather than dampening it. This can lead to runaway warming and melting of ice, which can have severe impacts on the global climate and sea level rise.
This positive feedback loop is known as the ice-albedo feedback, where the albedo is the measure of the reflectivity of a surface. The ice has a high albedo (reflective) while the water has a low albedo (non-reflective), meaning that more heat is absorbed by the water than the ice, leading to a temperature increase.
Answer: It is a positive feedback loop because it responds to an increase in temperature with a change that further increases the temperature.

C)Carbon dioxide is only released into the atmosphere by plants, animals, and bacterial decomposers.
D)Carbon dioxide is released into the atmosphere by plants, animals, bacterial decomposers, and human activities.
Carbon dioxide is released into the atmosphere by plants, animals, bacterial decomposers, and human activities.
What is Carbon dioxide?An essential component of the Earth's atmosphere is the colorless gas known as carbon dioxide .
Carbon dioxide exists in the atmosphere naturally and is also released into the atmosphere as a result of human activity such as the burning of fossil fuels, making cement, and decomposers.
In addition to being necessary for plant growth, carbon dioxide also plays a role in controlling the climate and decomposers of the planet.
One carbon atom is covalently doubly linked to two oxygen atoms in each molecule that makes up carbon dioxide, a chemical compound.
When the temperature is ambient, it exists as a gas.
Carbon dioxide functions as a greenhouse gas because it absorbs infrared light despite being transparent to visible light when it is in the air.

Is the gene that causes hemophilia recessive or dominant? Use the image to explain your reasoning.
I don't see a provided imagine but I can answer your question.
The gene that causes hemophilia is recessive. Hemophilia is caused by a mutation in the gene that codes for clotting factors VIII (hemophilia A) or IX (hemophilia B). The normal version of these genes is dominant, meaning that it masks the effects of the mutant gene. But when there are two copies of the mutant gene, one inherited from each parent, the lack of clotting factors leads to the bleeding disorder. The individual must inherit two copies of the gene (one from each parent) in order for the disorder to manifest. Hemophilia is often inherited in an X-linked recessive pattern, which means that the gene responsible for the disorder is located on the X chromosome.

The bones, which also produce red and white blood cells, store minerals, provide the body structure and support, and allow motion, protect the body's other organs.
Bones come in a range of shapes and sizes and have complex internal and exterior systems. They have a number of uses and are both light and sturdy. A group of specialized bone cells weave a complicated web of bonded minerals and a flexible matrix, which together make up around 70% of bone and prevent it from being evenly solid. Bones' distinctive make-up and structure enable them to be reasonably strong and hard while still being light.
The elastic collagen fibres, also known as ossein, make up 90 to 95% of the bone matrix, with the remaining material being crushed up. Collagen's flexibility increases fracture resistance. The binding of the inorganic mineral salt calcium phosphate into the chemical structure known as bone mineral, a kind of calcium hydroxyapatite, hardens the matrix. The mineralization process is what gives bones their stiffness.
Through the course of life, certain bone cells called osteoblasts and osteoclasts actively build and remodel bone. The tissue is intertwined into two basic patterns called cortical and cancellous bone, each with a distinct appearance and properties, within any given bone.

What are 2 moles of oxygen atoms?
2 moles of oxygen atoms are 1.2044 x10²⁴ atoms
A lot of atoms or molecules are referred to as a "mole" in chemistry. A mole (mol) denotes 6.022 x 10²³ things, just as a dozen implies 12 things. We use the number 6.022 x 10²³often known as Avogadro's number after the 19th-century chemist Amedeo Avogadro, to denote macroscopic quantities of atoms and molecules in chemistry. As a result, we refer to 6.022 x 10²³ O atoms as 1 mol of O atoms.
Due to the fact that each oxygen molecule contains two oxygen atoms, a mole of oxygen gas, with the chemical formula O₂, weighs 32 g and contains 6.02 X 10²³ molecules of oxygen,thus
2moles of oxygen = 2 X 6.02 X 10²³) atoms.

which part of the eye changes the shape of the lens?
Answer: The ciliary muscle
Explanation:
The ciliary muscle is a ring-shaped muscle located around the circumference of the eye's lens. It is responsible for changing the shape of the lens by contracting or relaxing.
When the ciliary muscle contracts, it loosens the zonules (fibers that hold the lens in place) that attach the lens to the ciliary body. This allows the lens to become flatter, which is necessary for focusing on distant objects. On the other hand, when the ciliary muscle relaxes, the zonules tighten, causing the lens to become thicker and more rounded. This allows the eye to focus on close objects.
This process is called "accommodation", by which the eye is able to adjust the shape of the lens to focus on objects at different distances.
