Because the theory of Heliocentrism is contrary to the theory of Geocentrism which places the Sun as the center of the solar system. In contemporary science, we can know that the sun is the core or axis of the Milky Way galaxy. And there are many other galaxies that are millions of light-years away from the Milky Way.

<h2>Further explanation </h2>

In astronomy, heliocentrism is an astronomical model in which the earth surrounds the sun at the center of the solar system. <em>The word comes from the Greek (Helios = Sun, and kentron = center).</em> Historically, heliocentrism is opposed to geocentrism, which places the Earth at the center of the universe.

Geocentric theory put forward by several philosophers such as Amaximandaros, Aristotle, Hipparchus, and at its peak Ptolomeus made maps of celestial objects in the Almagest book known as the Geocentric model or Ptolemic System (Taken from the name Ptolomeus).

Until now, these theories are still unable to determine the basis of our astronomy. Each theory still has advantages and disadvantages that can influence the development of the theory going forward. For the time being, the theory we use is the Heliocentric Theory. But for the future, we will not know-how.

The solar system is the arrangement of celestial bodies that revolve around the sun at its center. The celestial bodies consist of 8 planets with elliptical orbits, natural satellites, comets, asteroids, and meteoroids. The planets are always moving around the sun due to the influence of the sun's gravitational force.

Scientists divide 8 planets in the solar system into groups based on various factors that are owned by each planet. The following are three planetary arrangements or sequences made by astronomers:

  • First, grouping based on the position of planets viewed from Earth's orbit can be divided into inferior planets and superior outer planets. Inferior planets are planets located in Earth's orbit, namely Mercury and Venus. Meanwhile, superior planets are planets that are outside the orbit of the earth, namely the planets Mars, Jupiter, Saturn, Uranus, and Neptune.
  • Second, the grouping is based on its constituent materials which can be divided into 2, namely terrestrial planets and jovian planets. Terrestrial planets are planets with a relatively small size, rocky, and have a thin atmosphere. The combined planets are Mercury, Venus, Earth, and Mars. Meanwhile, the rest includes the Jovian planet. Namely planets with surfaces composed of gas, liquid, thick ice, and relatively large size.
  • Third, the grouping is based on its location as seen from the asteroid's orbit. Planets can be divided into outer planets and inner planets. Inner planets are planets that are in the asteroid's orbit, namely Mercury, Venus, Earth, and Mars. While the rest including the outer planets.

Prior to the discovery and elaboration of Copernicus with the theory of heliocentricism, which states that the sun is the center of the universe and that the planets orbit around it in a circular manner. The theory of geocentrism was first published by another astronomer and philosopher, Ptolemy. As a custom in the early years of the society, people already stood for the idea that the earth is the center of the universe which is easy to believe at that time given that their perspective shows that the sun moves when observed from earth's atmosphere.

An apparatus like the one Cavendish used to find G has large lead balls that are 5.2 kg in mass and small ones that are 0.046 kg.
Ber [7]

Answer:

The magnitude of gravitational force between two masses is 4.91\times 10^{-9}\ N.

Explanation:

Given that,

Mass of first lead ball, m_1=5.2\ kg

Mass of the other lead ball, m_2=0.046\ kg

The center of a large ball is separated by 0.057 m from the center of a small ball, r = 0.057 m

We need to find the magnitude of the gravitational force between the masses. It is given by the formula of the gravitational force. It is given by :

F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67259\times 10^{-11}\times \dfrac{5.2\times 0.046}{(0.057)^2}\\\\F=4.91\times 10^{-9}\ N

So, the magnitude of gravitational force between two masses is 4.91\times 10^{-9}\ N. Hence, this is the required solution.

If a CFOC was launched and travels 65 meters and is in the air for 3 seconds, what is the launch velocity and angle?
labwork [276]

Answer:

Lauch velocity (u) = 26.15 m/s

Lauch Angle (θ) = 35°

Explanation:

From the question given above, the following data were obtained:

Range (R) = 65 m

Time of flight (T) = 3 s

Acceleration due to gravity (g) = 10 m/s²

Lauch velocity (u) =?

Lauch Angle (θ) =?

R = u²Sin2θ /g

65 = u² × Sin2θ /10

Recall:

Sin2θ = 2SinθCosθ

65 = u² × 2SinθCosθ / 10

65 = u² × SinθCosθ / 5

Cross multiply

65 × 5 = u² × SinθCosθ

325 = u² × SinθCosθ .....(1)

T = 2uSinθ / g

3 = 2uSinθ / 10

3 = uSinθ / 5

Cross multiply

3 × 5 = uSinθ

15 = u × Sinθ

Divide both side by Sinθ

u = 15 / Sinθ....... (2)

Substitute the value of u in equation (2) into equation (1)

325 = u² × SinθCosθ

u = 15 / Sinθ

325 = (15 / Sinθ)² × SinθCosθ

325 = 225 / Sin²θ × SinθCosθ

325 = 225 × SinθCosθ / Sin²θ

325 = 225 × Cosθ / Sinθ

Cross multiply

325 × Sineθ = 225 × Cosθ

Divide both side by Cosθ

325 × Sineθ / Cosθ = 225

Divide both side by 325

Sineθ / Cosθ = 225 / 325

Sineθ / Cosθ = 0.6923

Recall:

Sineθ / Cosθ = Tanθ

Tanθ = 0.6923

Take the inverse of Tan

θ = Tan¯¹ 0.6923

θ = 35°

Substitute the value of θ into equation (2) to obtain the value of u.

u = 15 / Sinθ

θ = 35°

u = 15 / Sin 35

u = 15 / 0.5736

u = 26.15 m/s

Summary:

Lauch velocity (u) = 26.15 m/s

Lauch Angle (θ) = 35°

Calculate the sample standard deviation and sample variance for the following frequency distribution of hourly wages for a sampl
ollegr [7]
<h2>Answer:</h2>

(a) standard deviation = σ = 4.9996

(b) variance = σ² = 24.996

<h2>Explanation:</h2><h2 />

<em>Given frequency table (find attached as Table 1);</em>

<u></u>

(a) To find the sample standard deviation and sample variance, follow these steps;

<em>i. Calculate the mid-point c for each group by using the mid-point formula;</em>

c = (lower bound + upper bound) / 2

=> c = (6.51 + 8.50) / 2 = 7.505

=> c = (8.51 + 10.50) / 2 = 9.505

=> c = (10.51 + 12.50) / 2 = 11.505

=> c = (12.51 + 14.50) / 2 = 13.505

=> c = (14.51 + 16.50) / 2 = 15.505

<em>So the new table becomes (find attached as Table 2);</em>

<em>ii. Calculate the total number of samples (n) which is the sum of all the frequencies.</em>

n = 50+18+42+20+46

n = 176

<em>iii. Calculate the mean (M)</em>

This is done by first multiplying the midpoints by the corresponding frequencies and then dividing the result by the total number of samples (n).

M = [(7.505 x 50) + (9.505 x 18) + (11.505 x 42) + (13.505 x 20) + (15.505 x 46)] / 176

M = [375.25 + 171.09 + 483.21 + 270.1 + 713.23] / 176

M = [2012.88] / 176

M = 11.44

<em>iv. Find the variance (σ²);</em>

The variance is calculated using the following formula

σ² = [Σ(f x c²) - (n x M²)] / (n - 1)                ------------(i)

Where;

f = frequency of each boundary data point

<em>=>  Let's first calculate </em>Σ(f x c²).

This is done by finding the sum of the product of the frequency (f) of each boundary point and the square of their corresponding mid-points(c)

Σ(f x c²) = [(50 x 7.505²) + (18 x 9.505²) + (42 x 11.505²) + (20 x 13.505²) + (46 x 15.505²)]

Σ(f x c²) = [(2816.25125) + (1626.21045) + (5559.33105) + (3647.7005) + (11058.63115)]

Σ(f x c²) = 24708.1244

<em>=> Now calculate (n x M²)</em>

n x M² = 176 x 11.44²

n x M² = 23033.7536

<em>=> Now substitute these values into equation (i) to calculate the variance</em>

σ² = [Σ(f x c²) - (n x M²)] / (n - 1)

σ² = [24708.1244 - 23033.7536] / (176 - 1)

σ² = [4374.3708] / (175)

σ² = 24.996

Therefore, the variance is 24.996

<em>v. Find the standard deviation (σ)</em>

The standard deviation is the square root of the variance. i.e

σ = √σ²

σ = √24.996

σ = 4.9996

Therefore, the standard deviation is 4.9996
