The answer is the big bang witch goes as follows
The Big Bang model is that the universe begun in an extremely dense and hot condition and has expanded. The theory suggests, and measurements show, that the universe is still expanding today.
The Big Bang is a scientific theory about how the universe started, and then made the stars and galaxies we see today.
The universe began as a very hot, small, and dense superforce (the mix of the four fundamental forces), with no stars, atoms, form, or structure (called a "singularity"). Then about 13.8 billion years ago,[1] space expanded very quickly (thus the name "Big Bang"). This started the formation of atoms, which eventually led to the formation of stars and galaxies. It was Georges Lemaître who first noted (in 1927) that an expanding universe could be traced back in time to an originating single point. The universe is still expanding today, and getting colder as well.
As a whole, the universe is growing and the temperature is falling as time passes. Cosmology is the study of how the universe began and its development. Scientists who study cosmology agree that the Big Bang theory matches what they have observed so far. although there are flaws in this theory such as where did the explosion come from and even if u could find a way to explain the creation of the explosion itself there is the tiny fact that u cant create something from nothing however there would be starting material in this theory it wouldn't simply create more and since the theory states that the world will grow infinitely this is impossible but as i said it is a theory and the most accepted at that

The metricsystem was first put into practice in 1799, during the French Revolution, when the existing system of measures became impractical for trade and was supplanted by a decimal system based on the kilogram and the meter.
What is metric system?
During the FrenchRevolution, the existing system of measures became impractical for trade and was replaced by a decimalsystem based on the kilogram and the meter, and the metricsystem was born.
In 1793, the meter was defined as one ten-millionth of the distance from the equator to the NorthPole along a great circle, implying that the Earth's circumference is approximately 40000 km.
The meter was redefined in 1799 in terms of a prototype meter bar.
The meter was introduced as a new unit of length, defined as one ten-millionth of the shortestdistance between the NorthPole and the Equator passing through Paris, assuming an Earth flattening of 1/334.
Thus, this is the history of the metric system as it applies to the meter.

Answer and explanation;
In 1670 Gabriel Mouton, Vicar of St. Paul’s Church and an astronomer proposed the swing length of a pendulum with a frequency of one beat per second as the unit of length.
In 1791 the Commission of the French Academy of Sciences proposed the name meter to the unit of length. It would equal one tens-millionth of the distance from the North Pole to the equator along the meridian through Paris.It is realistically represented by the distance between two marks on an iron bar kept in Paris.
In 1889 the 1st General Conference on Weights and Measures define the meter as the distance between two lines on a standard bar that made of an alloy of 90%platinum with 10%iridium.
In 1960 the meter was redefined as 1650763.73 wavelengths of orange-red light, in a vacuum, produced by burning the element krypton (Kr-86).
In 1984 the Geneva Conference on Weights and Measures has defined the meter as the distance light travels, in a vacuum, in 1299792458⁄ seconds with time measured by a cesium-133 atomic clock which emits pulses of radiation at very rapid, regular intervals.

the energy needed to add an electron to an atom
Answers
Answer;
-The energy needed to split an atom into separate protons, neutrons, and electrons
Explanation;
E = mc² The equation is derived directly from Einstein’s Special Theory of Relativity .
Each of the letters of E = mc2 stands for a particular physical quantity. Writing them out in full we get:
Energy = mass × the speed of light squared
In other words: E = energy (measured in joules, J), m = mass (measured in kilograms, kg), c = the speed of light (measured in metres per second, ms-1), but this needs to be squared.
Explanation :
Einstein's equation is given by :
..............(1)
m is the mass
c is the speed of light
The energy needed to split an atom into separate protons, neutrons, and electrons can be calculated by using equation (1).
The energy needed to split the nucleus into separate protons and neutrons is called nuclear binding energy.
The energy needed to remove an electron from an atom is called ionization energy.
The energy needed to add an electron to an atom is called electron affinity.
So, the correct option is (A).

Answer: 192.9N and 91.1N
Explanation:
Let the force exerted by one person = X
Let the force exerted by the other person = y
Then, we can create equations
When both persons pull in the same direction, then
X + Y = 200 * 1.42
When both persons pull I'm opposite directions, then
X - Y = 200 * 0.509
Now we have
X + Y = 284
X - Y = 101.8
When we add the 2 equations together, we get
2X = 385.8
X = 385.8/2
X = 192.9
If x = 192.9, then, y = 284 - x
Y = 91.1
Therefore, one person exerts 192.9N, and the other exerts 91.1N

The frequency doesn't depend on the wave speed.
Frequency is simply the reciprocal of the period.
Frequency= 1 / (3sec) = 1/3 per sec = 1/3 Hz.
