Answer:

♡ hi fairy ♡

-- The Earth's rotation is gradually slowing.

The Earth was once believed to be the centre of the universe.

Earth has a powerful magnetic field.

There is only one natural satellite of the planet Earth.

Earth is the only planet not named after a god.

The Earth is the densest planet in the Solar System.

Using evidence from the article, defend the concept that Earth’s magnetic poles have swapped places over time.
Mamont248 [21]

Answer: Scientists found evidence of Earths magnetic field reversal in rocks on the ocean floor at plate boundaries. These rocks have alternating polarity due to magnetization that occurred during their cooling period. Using radio metric dating, scientist estimate that reversals occur approximately every several hundred thousand years.

A 15 N force and a 45 N force act on in object in opposite directions. What is the net force on the object?
vovikov84 [41]

Answer:

30N in the direction the 45N acts.

Explanation:

Fnet = F1 + F2 (the vector sum of the forces)

Assigning a positive direction to the 45N force and a negative direction to the 15N force gives:

Fnet = 45 - 15

Fnet = 30N

Since the answer is positive, it is in the direction the 45N force acts.

Explain partial eclipse and total eclipse for lunar eclipse in detail and summarise
melomori [17]

Answer:

A total eclipse occurs when the dark silhouette of the Moon completely obscures the intensely bright light of the Sun, allowing the much fainter solar aureole to be visible. During any one eclipse, totality occurs at best only in a narrow track on the surface of Earth. This narrow track is called the path of totality.

A partial lunar eclipse happens when part of the Moon enters Earth's shadow. In a partial eclipse, Earth's shadow appears very dark on the side of the Moon facing Earth.

A standard baseball has a circumference of approximately 23 cm. if a baseball had the same mass per unit volume (see tables in s
OleMash [197]

In order to determine the mass of a standard baseball if it had the same density (mass per unit volume) as a proton or neutron, we first determine the volume of the baseball. The formula to be used is V_sphere = (4/3)*pi*r^3. In this case, the radius r can be obtained from the circumference C, C = 2*pi*r. After plugging in C = 23 cm to the equation, we get r = 3.6066 cm. The volume of the baseball is then equal to 205.4625 cm^3.

Next, take note of these necessary information:

Mass of a neutron/proton = 10^-27 kg

Diameter of a neutron/proton = 10^-15 m

Radius of a neutron/proton = [(10^-15)/2]*100 = 5x10^-14 cm

<span>Thus, the density, M/V of the neutron/proton is equal to 1.9099x10^12 kg/cm^3. Finally, the mass of the baseball if it was a neutron/proton can be determined by multiplying the density of the neutron/proton with the volume of the baseball. The final answer is then a large value of 3.9241x10^14 kg.</span>
