When a neutral atom gains or loses electrons, it becomes charged and is called a(n)

Physics

Daniel [21]3 years ago

Answer:

It is called an ion.

Explanation:

Atoms of elements can lose or gain electrons making them no longer neutral, they become charged. A charged atom is called an ion. When an atom loses electron(s) it will lose some of its negative charge and so becomes positively charged. A positive ion is formed where an atom has more protons than electrons.

Describe how computer climate models help scientists understand possible future climate changes. How reliable are these computer
ExtremeBDS [4]
To predict future climate, scientists use computer programs called climate models to understand how our planet is changing. Climate models work like a laboratory in a computer. They allow scientists to study how different factors interact to influence a region's climate.


Now a new evaluation of global climate models used to project Earth's future global average surface temperatures over the past half-century answers that question: most of the models have been quite accurate.

15. A locomotive moved 18.0 m [W] in a time of 6.00 s and stopped. After stopping, the
mariarad [96]

Answer:

Distance = 30m

Displacement = 6m W

Explanation:

Given the following:

Movement 1 = 18m W

Movement 2 = 12m E

Diatance is a scalar quantity with only magnitude and no direction. That is, in Calculating the distance moved by the locomotive, the direction of travel or movement of the object is not considered. It only measures the total amount of movement made during the Time of motion.

Therefore, total distance traveled equals :

Movement 1 + movement 2

18m + 12m = 30m

B) Displacement also measures the movement made by an object. However, Displacement is a vector quantity and therefore, considers both magnitude and direction of travel of the object. Therefore, it measures the overall change in position of the object from its starting position.

Therefore, Displacement of the locomotive equals:

18m W - 12m E = 6m E

(b) Assuming h is small in comparison to the radius of the Earth, show that the difference in free-fall acceleration between two
Sholpan [36]

Vertical distance h isΔg=\frac{-2GM}{ RE^{3} }

<h3>What is vertical?</h3>
  • The distance between two vertical places is known as the vertical separation or vertical distance. There are numerous ways to express vertical position using vertical coordinates, including depth, height, altitude, elevation, etc.
  • The formula for vertical distance from the ground is y = - g * t2 / 2, where g is the acceleration of gravity and h is a height.
  • The vertical distance between the measurement point and the point of observation on Earth's surface. Altitude is the vertical distance from the measurement place to mean sea level.

Assuming h is small in comparison to the radius of the Earth, show that the difference in free-fall acceleration between two points separated by vertical distance h isΔg = (2GMeH) / RE³:

Given:

Separated between two points=h

And, h∠∠R_{E}           (R_{E}= radius of the Earth)

Now, \frac{dg}{dr} =\frac{-2GM}{ RE^{3} }

dg =\frac{-2GM}{ RE^{3} } dr

Δg=\frac{-2GM}{ RE^{3} }  

Therefore, Vertical distance h isΔg=\frac{-2GM}{ RE^{3} }
