The answer is 5000 NExplanation:
The force acting on a body can be found by using the formula
force = mass × accelerationFrom the question
mass = 10 kg
acceleration = 500 m/s²
We have
force = 10 × 500
We have the final answer as
5000 NHope this helps you

Explanation:
Express the measurement using the appropriate SI prefix. For example, 10.72 x 103m is the same as 10.72 km because the “k” stands for 103
8.09 x 10-6g
(I got super stuck on this)
Answer:
[tex]10.72 \times 10 {}^{3} m = 10.72km \\ 8.09 \times 10 {}^{ - 6} g = 8.09 \times 10 {}^{ - 9} kg \\ \\ note : \\ to \: convert \: to \: \: k(units) \: you \: divide \: the \: value \: by \: {10}^{3} . \\ 5m \: to \: km \: will \: be : \\ \frac{5}{1000} km = {5 \times 10}^{ - 3} km[/tex]

Human Movement is important because it most commonly used to insure optimal athletic ability. It can also be used to identify the cause of most common sports injuries and movement-related problems. The name for this type of study is called Kinesiology. This is a very necessary part of students understanding dance, sports, and physical well-being. Studying Kinesiology results in better physical performance, as well as many cardiovascular improvements. Kinesiology is used to answer many still unknown question about human movement.

If Maria winks exactly 5 times every minute while she is awake and she sleeps exactly 8 hours a day, how many times does Maria wink in a day? winks/day.
Answer:4,800
Explanation:
5 winks a minute, 60 minutes in an hour.
300 winks an hour, 16 hours a day.
4,800.
Answer:
The answer is 4,800 winks per day.
Explanation: There are 24 hours in a day, 24 minus the 8 hours shes asleep is 16. There are 60 minutes in an hour. 5 x 60 is 300. 300 winks an hour multiplied by the 16 hours she's awake is 4,800.
How does an increase in the annual melt season in Antarctica have a global effect?
a.
It causes an increase in heat related illness and death.
b.
It causes the global concentration of carbon dioxide to decrease.
c.
The water in the melting glaciers can cause sea levels to rise.
d.
None of the above is true.
Please select the best answer from the choices provided
A
B
C
D
Answer:
The correct answer is option "C"
The water in the melting glaciers can cause sea levels to rise.
The increase in annual melt season indicates a prolonged melting (hot) season which is primarily due to the impact of global warming. Global warming is increasing the highest temperature mark in the hot seasons on the planet which is adversely affecting the polar regions of earth. The ice in these Polar Regions has started melting. This ice when converted into liquid form flows through regions to reach sea and oceans and thus causes the rising of sea level
The annual melt season in Antarctica produces a global effect because the water in the melting glaciers can cause sea levels to rise.
What is the annual melt season?The annual melt season refers to a period of time when the ice in cold and polar regions of the world begin to melt to form warm.
The melting of ice in these regions such as Antarctica results in a rise in the global sea levels.
Therefore, the annual melt season in Antarctica produces a global effect because the water in the melting glaciers can cause sea levels to rise.

Explanation:
The relative formula mass (M) of a Group 2 metal carbonate is 197
Relative atomic masses (Ar): C = 12
O = 16
Calculate the relative atomic mass (Ar) of the Group 2 metal in the metal carbonate
Name the Group 2 metal.
The relative atomic mass (Ar) : 137 and the element : Ba
Further explanationThe naming of chemical compounds is giving a special name to a compound that aims to facilitate the classification of compounds and facilitate the identification of a compound. The rules for naming chemical compounds have been determined by the IUPAC (International Union of Pure and Applied Chemistry)
This nomenclature includes the naming of ion compounds, covalent compounds, and polyatomic
The molar mass of a compound is given by the sum of the relative atomic mass of Ar
M AxBy = (x.Ar A + y. Ar B)
Group 2 metals have a +2 charge : M²⁺
So the compound of metal carbonate : MCO₃
Ar C = 12, O = 16
M MCO₃ = (1.Ar M + 1. Ar C+ 3. Ar O)
[tex]\tt 197=1. Ar~M+1.12+3.16\\\\197=Ar~M+12+48\\\\Ar~M=137[/tex]
The element with relative atomic masses 137 is Ba
So the compound : BaCO₃
True or False?
Solubility and melting point are two examples of physical properties.
Answer: True
Explanation:
Solubility is a physical property. The reason is because it can be determined by simple observation and does not change the chemical composition of the material. If the material is soluble, the solubility is the maximum amount of material that dissolves in a solvent at a given temperature.
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Answer: True
Explanation: These are both examples of physical properties
QUESTION 2: How is velocity different from speed? *

Compare and Contrast Heating and
Cooling curves.
Answer: Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid.

The atomic mass of an atom is calculated by adding up what two subatomic particles
The atomic mass of an atom is calculated by adding up protons and neutrons
Further explanationThere are two components that accompany an element, the mass number and atomic number
Atoms are composed of 3 types of basic particles (subatomic particles): protons, electrons, and neutrons
The charge of 1 proton is equal to a charge of 1 electron but has a different sign
The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)
The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.
Atomic number = number of protons = number of electrons ⇒ neutral number
Atomic mass is the sum of protons and neutrons
Atomic Number (Z) = Atomic mass (A) - Number of Neutrons

Buck described a complete circle in the air, and half of another, then crashed to the ground on his head and chest.

If the average atomic mass is 39.948amu, which isotope is more abundant?
Answer:
It depends on which element you are talking about. I appears that no element has an average atomic mass of that number. So, for the question, if it assumes that there are two isomers with 39 amu and 40 amu, then the 40 amu one would be more abundant. But again, there are different possible isotopes and I can't tell what the question wants.
