yoda is 500km above the surface of the earth. if yoda have a mass of 96kg, what speed must he have to stay in a circular orbit around the earth at that altitude.

Answer:

Kepler refined the Copernican model. Orbits are not circles along which planets move at a constant speed, but ellipses, in the central focus of which is the Sun. The planet moves in an ellipse with a variable speed depending on the distance to the Sun. On this basis, Kepler significantly simplified the Copernican model and formulated the laws of planetary motion in their orbits.

The chemical caffeine stimulates (increases activity in) your nerve system and brain. The structure of caffeine is shown in the image below:

On every nitrogen atom, there is a lone pair. There are five valence electrons on each nitrogen atom. Only three are used for bonding, leaving the other pairs to exist alone.

Each of the two oxygen atoms that are double-bonded additionally has two lone pairs. There are six valence electrons on each oxygen atom. The remaining four electrons are found in lone pairs since only two are required for bonding.

The hybridization of the atoms in the indicated region will then be determined.

We shall first determine whether the carbon atom has hybridized with the double-bonded oxygen atom. There are no lone pairs between the three atoms this carbon atom is linked to. Consequently, its hybridization is \(sp^2\).

The hybridization of the nitrogen atom will follow. This nitrogen atom is joined to two more atoms by a pair of non-bonded electrons. Thus, hybridization becomes \(sp^2\).

Finally, there are no lone pairs on the second carbon atom, which is connected to three other atoms. Because of this, its hybridization is \(sp^2\).

1. In ferromagnetic materials, the net magnetic moment arises from the alignment of electron spins when a magnetic field is applied.

2. Magnetotactic bacteria and certain animals, such as lobsters, honeybees, homing pigeons, and sea turtles, are believed to possess magnetite in their bodies, allowing them to detect and navigate using the Earth's magnetic field.

1. Electrons in atoms have two kinds of intrinsic angular momentum, spin, and orbital momentum. The origin of ferromagnetism is attributed to the net magnetic moment of electrons in a ferromagnetic material's lattice.

The Pauli exclusion principle causes the electrons to be split between two possible spin directions, up and down. As a result, the total magnetic moment of the material is zero because it is composed of equal numbers of spin-up and spin-down electrons. When a magnetic field is applied to a ferromagnetic material, the magnetic moments of the electrons become aligned, causing the material to become magnetized.

2. Magnetotactic bacteria possess magnetite in their bodies. These bacteria utilize the earth's magnetic field for navigation purposes. Animals that are capable of magnetoreception are referred to as magnetotactic. Many organisms utilize the earth's magnetic field to locate their migratory paths or to locate prey.

1) The height from which the glasses fell is  278 m

2) The velocity at the time of the fall is 74 m/s

3) The acceleration of the hot balloon is 9.8 m/s^2

We know that we can obtain the height that the glasses started falling from by the use of the equation;

h = ut + 1/2 gt^2

h = height

u = initial velocity

g = acceleration due to gravity

It's worth noting that the negative signs in the lens equation and magnification formula indicate that the image formed by a diverging lens is always virtual and upright. This means that the light rays from the object are diverging when they reach the lens, and the lens bends the light rays so that they appear to be coming from a virtual image point on the opposite side of the lens.

In terms of the magnification, a magnification of 0.40 means that the image is 40% the size of the object, but it is also inverted. So, if the object is an upright arrow, the image will be a smaller, inverted arrow. It's also worth noting that a diverging lens always has a negative focal length, which means that it always forms virtual images that are smaller than the object. Diverging lenses are used in eyeglasses to correct nearsightedness, and in certain optical instruments to spread out light or reduce its intensity.

The magnification formula for a diverging lens is:

m = -di/do

where m is the magnification, di is the image distance, and do is the object distance.

The focal length (f) of the lens is related to the image and object distances by the lens equation:

1/f = 1/di + 1/do

Substituting the given value of focal length (f = -10 cm) into the lens equation, we get:

1/-10 cm = 1/di + 1/do

Simplifying this equation, we can rearrange it to solve for di:

di = -do / (m - 1)

Substituting the given magnification (m = 0.40) into this equation, we get:

di = -do / (0.40 - 1)

di = -do / (-0.60)

di = 1.67 do

Therefore, the image distance is 1.67 times the object distance. To find the object distance that gives a magnification of 0.40, we can set di = -0.40 do (since m = -di/do) and solve for do:

-0.40 do = 1.67 do

Simplifying this equation, we get:

do = di / (-0.40)

do = -1.67 di

Therefore, the object distance that gives a magnification of 0.40 is 1.67 times the image distance. If we assume that the image is formed at the lens' focal length (di = -10 cm), then the object distance is:

do = -1.67 di

do = -1.67 (-10 cm)

do = 16.7 cm

Therefore, the object distance at which the magnification is 0.40 is 16.7 cm.

Answer:

Covalent bond.

Explanation:

There are 4 main types of bonds:

Covalent, ionic, metallic, and hydrogen.

Covalent bond: Involves the sharing of pairs of electrons, here the difference between the electronegativity of the atoms is not too large. Covalent bonds usually form an octet of electrons.

Ionic bond: This happens because the electrostatic attraction between the atoms whit very different electronegativities

Hydrogen bond: Electrostatic attractive force between an electronegative atom and a hydrogen atom covalently bonded to another electronegative atom.

Metallic bond: Type of bond that makes the metallic atoms to stay really tightly together. The atoms bond because of the electrostatic atractive force between conduction electrons and positively charged metal ions.

Now, in this case, we have the bond between Nitrogen (electronegativity = 2.0) and Hydrogen (electronegativity = 2.1)

So we can see that:

The elements are not metals, so we can discard metallic bond.

For a hydrogen bond, we need 3 atoms (one of which is hydrogen), here we have two, so we can discard this option.

Ionic bond needs different electronegativities, here the electronegativities are really close together, so the ionic bond can be discarded.

we can conclude that the bond will be a covalent bond.
