Answer: 11 electrons.

Explanation:

Atoms in their neural state, that is, uncharged or non ionized state, always have the same number of protons and electrons.

When they ionized, they will either gain or lose electron or electrons which will eventually make them either positively charged or negatively charged.

Given that an electrically neutral atom has 11 protons. It will definitely has 11 electrons orbiting around it’s nucleus

Answer: potassium

Explanation: An atom of potassium would have a very easy time losing one electron to form an ionic bond with an atom of an element that would easily accept it.

Group 1 elements like sodium (Na) have one electron in their outer shell, which they can easily lose to form ions and create ionic bonds. When sodium bonds with chlorine (Cl), it loses one electron and becomes a positive ion, while chlorine gains that electron to become a negative ion, resulting in the formation of sodium chloride (NaCl).

The element in question is likely from Group 1 of the periodic table, also known as the alkali metals. These elements, such as sodium (Na), have a single electron in their outermost shell. This lone electron is easily lost during chemical reactions, forming a positive ion (a cation), and allowing the atom to attain a more stable electron arrangement.

An example of such a reaction is when sodium forms an ionic bond with chlorine (Cl) to create sodium chloride (NaCl), commonly known as table salt. Chlorine, as a halogen from Group 7A, readily accepts the lone electron from sodium because it has seven electrons in its valence shell and needs only one more to complete its octet, becoming a negative ion (an anion).

Consequently, the sodium atom becomes a sodium ion (Na+) and the chlorine atom becomes a chloride ion (Cl-). This exchange of electrons is the basis of an ionic bond, which is a type of chemical bond where a metal cation and a nonmetal anion are attracted to each other due to their opposite charges.

Answer:

high tides I hope it's correct ! Have a wonderful day

Ocean bulges or tides are caused by lunar and solar gravitational forces. The area between two ocean bulges is referred to as a tidal trough. There are direct tide and opposite tide on the planet due to varied gravitational field.

Ocean bulges are primarily caused by the gravitational pull of the moon and the sun on the Earth. These bulges, referred to as tides, occur on both sides of the planet specifically the side facing the moon and the side opposite to it. This is due to the varying intensity of the gravitational field across the Earth's surface. The area between these bulges is known as the tidal trough.

The tide that faces the moon is the result of the lunar gravitational pull and it's called direct tide. The tide on the opposite side, also known as the opposite tide, occurs because the Earth is pulled toward the moon more than the water on the far side, creating another bulge.

Ocean Bulges:

Ocean bulges are caused by gravitational forces exerted by the moon and the sun on the Earth's oceans. This causes the water to bulge, creating areas of higher water level or high tide. The gravitational forces create the bulges by pulling the water towards the moon and the sun.

The Area between Bulges:

The area between bulges of water in the ocean is called the trough. It is the region of lower water level or low tide that lies between the bulges caused by the gravitational forces. During low tide, the water level is lower in this area.

Example:

An example of ocean bulges and the area between them can be seen in the tidal patterns. As the moon orbits the Earth, its gravitational pull causes bulges on the side of the Earth facing the moon and the opposite side. The area between these bulges experiences lower water levels, forming the trough.

The speed of the truck, given the frequency and the speed of sound would be 6.2 m/s

Given:

Fs = 500 Hz (source frequency)

Fo = 480 Hz (observed frequency)

v = 348 m/s (speed of sound)

Using the Doppler effect formula:

Fo = Fs × (v / (v + vs))

where vs is the source velocity (truck velocity), we can solve for vs:

480 = 500 × (348 / (348 + vs))

Simplifying and solving for vs:

0.96 = 348 / (348 + vs)

0.96(348 + vs) = 340

334.08 + 0.96vs = 340

0.96vs = 5.92

vs = 5.92 / 0.96

vs ≈ 6.2 m/s

Therefore, the truck is moving away from the observer at a speed of approximately 6.2 m/s.

Explanation:

bc the light has to be refracted (aka has to be inside water)at a angle to see a rainbow with are eyes

Rainbows are formed when sunlight enters a raindrop, bends (refracts), reflects off the inside surface, and exits, refracting again. This process separates sunlight into its component colors, leading to the beautiful spectrum of a rainbow. The crucial factors for a rainbow's formation are refraction, reflection, and dispersion within the raindrop.

To understand how rainbows are formed, it's essential to explore the interaction between sunlight and raindrops. Rainbows occur due to a combination of refraction, reflection, and dispersion of sunlight within raindrops. When sunlight enters a raindrop, it bends or refracts because light travels slower in water than in air. This bending of light varies with wavelength, causing the light to spread out into a spectrum of colors.

The reflection part happens inside the raindrop. After refraction, the light rays hit the back of the raindrop and reflect off the inside surface. This reflection changes the direction of the light within the drop, sending it back toward the front of the raindrop where it refracts again as it exits back into the air. Different colors of light bend by different amounts during refraction, which disperses the light into a spectrum of colors that we see as a rainbow.

Interestingly, the position and size of the rainbow you see are determined by the collection of raindrops reflecting light back to your eyes at the precise angle required for the colors to be observable. Each color exits the raindrop at a slightly different angle, leading to the formation of the circular arc of the rainbow. Red light is refracted and reflected at angles that make it appear on the top of the rainbow, while violet light appears on the bottom. Thus, the creation of a rainbow relies on sunlight bouncing off the inside of a raindrop, not the outside.

Answer:

C) Sphere C because it is larger than A and closer than B.

Answer: 2 and 4

Explanation:

Final answer:

The strength of the electrical force between two objects is directly proportional to the strength of their charges and inversely proportional to the square of the distance between them. Increasing either charge or decreasing distance results in a stronger electrical force.

Explanation:

The factors affecting the strength of an electrical force between two objects are influenced by their charge and distance from each other. Specifically:

The stronger the charge on two objects, the stronger the electrical force between them.

The closer together two objects are, the stronger the electrical force between them.

These factors are rooted in the principles of electrostatics, which explain that electrical forces are proportional to the product of the charges of the objects involved and inversely proportional to the square of the distance between them. Thus, increasing the charge amplifies the force, and reducing the distance between charges also results in a stronger electrical attraction or repulsion.

Answer:

v_oy = 16.33 m/s

Explanation:

To find the vertical velocity of the tiger, you use the information about the horizontal velocity and maximum horizontal distance traveled.

You use the following formula for the range of the trajectory:

[tex]x_{max}=\frac{2v_{ox}v_{oy}}{g}[/tex]     ( 1 )

v_ox: horizontal initial velocity = 4.5m/s

v_oy: vertical initial velocity = ?

g: gravitational acceleration = 9.8m/s^2

x_max: range of the trajectory = 15 m

You do v_oy the subject of the formula ( 1 ) and you replace the values of the other parameters in order to calculate v_oy:

[tex]v_{oy}=\frac{gx_{max}}{2v_{ox}}=\frac{(9.8m/s^2)(15m)}{2(4.5m/s)}\\\\v_{oy}=16.33\frac{m}{s}[/tex]

hence, the initial vertical velocity of the tiger is 16.33m/s

Bar graphs show comparisons between qualitative data (in this case the driver) and quantitative data (the number of crashes)

Explanation:

Final answer:

A bar or column graph is most suitable for showing a comparison of crash records for different NASCAR drivers, as it effectively illustrates differences in discrete categories.

Explanation:

To show a comparison of the crash records of different NASCAR drivers, a bar graph or a column graph would be most appropriate.

This type of graph efficiently compares discrete categories—in this case, individual drivers—and shows the number of crashes associated with each one.

Each driver would be represented by a separate bar, and the length of the bar would correspond to the number of crashes they've had, allowing for a clear visual comparison.

While a line graph is suitable for demonstrating the relationship between two changing variables, such as a time series analysis of data, it is not the ideal choice for this particular scenario since we are looking at individual, discontinuous categories rather than a continuous dataset over time.

The Fermi paradox can potentially be explained by the idea that aliens are deliberately not contacting us. Other theories suggest rare intelligent life, undetectable communications, or self-destruction of advanced civilizations.

A potential explanation to resolve the Fermi paradox is that aliens are intentionally isolating us or refusing to communicate with us (Option D). This concept suggests that advanced civilizations may make it a practice not to interfere with planets harboring immature, developing species such as humans. Other resolutions refer to life being common while intelligent life is rare, the possibility that invisible streams of data are beyond our detection capabilities, or the theory that civilizations self-destruct upon reaching a certain technological level. Considering the Drake Equation, each term estimates the likelihood of alien civilizations, but many values are guessed due to our limited knowledge.

A positive symptom of schizophrenia would be an additional abnormal behavior, such as hallucinations, delusions, or catatonia, indicating the patient is experiencing psychosis.

A positive symptom of schizophrenia would be an abnormal behavior or experience that a person without schizophrenia would typically not have. These symptoms indicate an excess of certain functions and indicate that the patient has lost contact with reality, a condition known as psychosis. Examples of positive symptoms include hallucinations, which involve perceiving something that is not there, such as hearing voices when none are actually present. Other positive symptoms can consist of delusions, where a patient harbors strong beliefs despite clear evidence to the contrary, derailment which is the manifestation of disorganized thinking that can cause speech and reasoning to be disconnected and illogical, disorganized behavior, inappropriate affect, where emotional responses do not align with the context of the situation, and catatonia, which includes a range of motor disturbances such as holding the body in unusual positions.

Positive symptoms basically are exaggerations or distortions of normal behavior and indicate a psychotic phase of schizophrenia, where patients demonstrate symptoms that add to their typical behavior.
