Simulating Earth's gravity in space would be challenging, but it is possible to create artificial gravity using centrifugal force. Centrifugal force is the outward force experienced by an object that is moving in a circle.
What is gravity?An unobservable force that draws things together. Anyone remains on the ground thanks to Earth's gravity, which also causes objects to fall.
One way to create artificial gravity in space is by building a rotating space station. The station would consist of two main parts: a central hub and a rotating section.
The hub would contain the crew quarters, life support systems, and other essential components, while the rotating section would be attached to the hub via a set of cables or other structures.
The rotating section would be set spinning, creating centrifugal force that would push the crew towards the outer rim of the section. This force would create a sensation of gravity that would be similar to that experienced on Earth.
Thus, by rotating a spacecraft, it is possible to create a centrifugal force that mimics the gravitational force of Earth.

distinguish between the climates of a coastal location and a location in the center of a large continent.
Answer:
Climatic condition in coastal regions is milder than the climatic conditions in the continental regions.
Explanation:
Climate in coastal regions is mild. It has both hot summers and winters accompanied by sea breezes. Precipitation and humidity is high in coastal areas. Both the summers and winters have a mild temperature range.
While in continental regions both summer and winters undergo extreme conditions. Summers are extremely hot and winters are extremely cold. They have wide range of climatic exposures such as rainy season, autumn season and spring season in between summer and winter season.
why it is dangerous for people to continue to travel into space?
Answer:
The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.

what is one thing that would make evidence from an experiment more reliable? A if there was no comparison group B if there was a small sample C if the source of the information was an expert D it is not D i tried D already
Answer:
Explanation:
When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and gets very similar results then those results are said to be reliable. Reliability is measured by a percentage – if you get exactly the same results every time then they are 100% reliable.

O
the mass of the atoms of the product(s) is greater than those of the reactants).
O

a new substance(s) with the same number of atoms as the initial substance(s) is
tormed
Answer: a new substance(s) with the same number of atoms as the initial substance(s) is formed
Explanation:
Chemical reaction is a reaction in which there is rearrangement of atoms and thus new substance is formed.
According to the law of conservation of mass, mass can neither be created nor be destroyed in chemical reaction. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

In chemical equilibrium, the equilibrium constant is greater than reaction quotient that is Q< Keq.
What is chemical equilibrium?Chemical equilibrium is defined as the condition which arises during the course of a reversible chemical reaction with no net change in amount of reactants and products.A reversible chemical reaction is the one wherein the products as soon as they are formed react together to produce back the reactants.
At equilibrium, the two opposing reactions which take place take place at equal rates and there is no net change in amount of the substances which are involved in the chemical reaction.At equilibrium, the reaction is considered to be complete . Conditions which are required for equilibrium are given by quantitative formulation.
Factors which affect chemical equilibrium are change in concentration , change in pressure and temperature and presence of catalyst.

Third Blank - A. Reached earths atmosphere
Explanation:
The given image shows celestial object called meteor.
The meteor is often called shooting star as it produces a streak of light. When a meteoroid reaches Earth's atmosphere, it experiences a friction which allows the meteoroid to burn up and produce a streak of light in the sky.
Hence, the correct answer for blanks is Meteor, a streak of light and Reached earths atmosphere.

Using m1v1=m2v2,a 0.5 liters of 12 Molarity solution of NaCl was added to a 2.0 liters of water,find out the final molarity of this 2.5 liter solution
Answer:
2.4 M
Explanation:
The dilution formula, M1V1 = M2V2, states that the initial molarity times the initial volume equals the final molarity times the final volume. Plug in the values and solve for M2:
12 M * 0.5 L = M2 * 2.5 L
6 = M2 * 2.5 L
M2 * 2.5 L = 6
M2 = 6 / 2.5 = 2.4 M

How many moles of H+ ions are needed to neutralized 3 Liters of 8M
NaOH?*
Answer:
Answer:
0.027 mole of NaOH.
Explanation:
We'll begin by obtaining the number of mole H2SeO4 in 45mL of 0.30M H2SeO4
This is illustrated below:
Molarity of H2SeO4 = 0.3M
Volume of solution = 45mL = 45/1000 = 0.045L
Mole of H2SeO4 =...?
Mole = Molarity x Volume
Mole of H2SeO4 = 0.3 x 0.045
Mole of H2SeO4 = 0.0135 mole
Next, the balanced equation for the reaction. This is given below:
H2SeO4 + 2NaOH –> Na2SeO4 + 2H2O
From the balanced equation above,
1 mole of H2SeO4 required 2 moles of NaOH.
Therefore, 0.0135 mole of H2SeO4 will require = 0.0135 x 2 = 0.027 mole of NaOH.
Therefore, 0.027 mole of NaOH is needed for the reaction.
