Answer: LEO satellites are low earth orbiting whereas GEO satellites are geostationary earth orbiting satellites.
Explanation: Satellites in low Earth orbit, or LEO, are the closest devices to Earth. You'll often hear the terms GEO and GSO used interchangeably, but they’re not always the same. Both types of satellites sit at roughly 22,300 miles above Earth’s surface, but the way they orbit is different.

The general kinematic equations of motion for vertical displacement can also be simplified significantly. Write the simplified
equation for y in this case. Explain how you have been able to simplify it from this general displacement equation:
Answer:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
Explanation:
The general kinematic equation for horizontal displacement is gives as:
Δx = v₀t + (1/2)at²
Where
Δx = change in the x direction
v₀ = initial velocity
t = time
a = acceleration
If the body is vertically instead of horizontally, Δx is changed to Δy
Δy = v₀t + (1/2)at²
For a vertical moving body, the acceleration it experiences is the gravitational accerelation of the earth 'g'
So the equation becomes:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
The general kinematic equations of motion for vertical displacement is written as [tex]h = v_0_yt - \frac{1}{2} gt^2[/tex].
The general kinematic equations of motion for vertical displacement is written as follows;
[tex]h = v_0_yt - \frac{1}{2} gt^2[/tex]
where;
h is the vertical displacement of the object[tex]v_0_y[/tex] is the initial vertical velocity of the objectg is the acceleration due to gravityt is the time of motion of the objectThus, the general kinematic equations of motion for vertical displacement is written as [tex]h = v_0_yt - \frac{1}{2} gt^2[/tex].

Mary is allergic to cats. Mary's friend, Sue, has a roommate who has cats. Whenever Mary visits Sue, Mary sneezes even before she enters Sue's house. Mary's sneezing persists even after Sue's roommate and his cats have moved out. After a while, Mary stops sneezing before she enters Sue's house. The point at which Mary's sneezing stopped is an example of _____.
Answer: Extinction
Explanation: Extinction simply means cessation. A condition whereby an action or behavior exhibited by an individual or organism eventually stops. In psychological parlance, extinction is usually attributed to the discontinuance of a certain behavior usually due to non - reinforcement or eventual absence of the conditioned stimulus.
In the scenario above, the point at which Mary stopped sneezing is called extinction which is due to the removal of the cat which is the cause of Mary's sneezing behavior.

In which of the following situations or places would you want to reduce the
force of friction?
I A. Skiing down a hill during a race.
B. Walking down a steep hill.
C. Sitting in the bed of a pickup truck while it turns a corner
D. In the axle of the wheels while you ride your bicycle.
Answer:
D
Explanation:
The correct answer would be in the axle of the wheels while you ride your bicycle.
Options A, B, and C requires that the forces of friction is increased in order to have more control.
However, option D requires that there is a minimal frictional force in the axle of the wheels of a bicycle while riding so that a little effort would be required to keep the bicycle moving.
The lesser the friction, the lower the effort that would be needed to keep the bicycle moving and vice versa.

An overhead projector lens is 32.0 cm from a slide (the object) and has a focal length of 30.1 cm. What is the magnification of the image? (Unit=cm) PLS HELP
Answer: M = 14.3
Explanation:
Given the following :
Object distance (u) = 32cm
Focal length (f) = 30.1 cm
Magnification = image distance (v) / object distance (u)
Recall ; 1/f = 1/u + 1/v
1/30.1 = 1/32 + 1/v
1/v = 1/30.1 - 1/32
1/v = (32 - 30.1) / 963.2
1/v = 2.1 / 963.2
1/v = 0.0021802
v = 1/0.0021802
v = 458.66666 cm
Therefore, Magnification 'M' = v / u
M = 458.66666 / 32
M = 14.333333
M = 14.3
Answer:
M = -15.8
Explanation:
object distance = 32cm
focal length = 30.1 cm
To find M we first need to find di or image distance
I will use the equation: 1/f = 1/di + 1/do
By changing the equation to 1/f - 1/di = 1/do we get 0.0019725
equation with numbers plugged in:
1/30.1 - (1/32) = 0.0019725
To change 1/do to do we divide 1 by 0.0019725
You should get 506.97
Now use the equation
M = -(di/do)
M = -(506.97/32)
You should get M = -15.8

The diagram illustrates the evolution of the universe, starting from the big bang. Each concentric circle represents a stage in the evolution as stated by the big bang theory. The arrows illustrate the changes that happened after the big bang and leading up to the stage where gases were formed that later led to the formation of stars and galaxies. Choose the inaccurate statements on the diagram.
Answer: The two correct answers are Universe became more dense and universe became less transparent.
Explanation: I took the test and those are correct
The incorrect statements on the diagram universe became more dense Universe became less transparent.
What is the universe?The universe is the whole cosmic system of matter and energy. The Earth, the Sun, the Moon, the planets, and the stars along with the dust, gases, and rocks form the universe.
The big bang is the theory that explains how the universe began. It says that the universe began with just a single point. It went on expanding and stretched to grow as large as possible. It is still now expanding.

What happens to the gravitational force between two objects as the distance between them decreases?
Answer:
gravitational force increases
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are brought closer to each other, the force of gravitational attraction between them also increases.
Given the resistivities below, which material is best described as an insulator?
A. 4.5 22•m
B. 2.8 x 10-8
12.m
C. 1.7 x 10-8 2•m
D. 3.2 x 108 2.m
Answer: D) 3.2 × 10^8
Explanation: Insulators are best described as materials which are poor conductors of electricity and hence do not allow passage of electricity through them. Resistivity are hence used to describe property or characteristic of a material which does not allow the flow or passage of electric current.
In summary, materials which high resistivity values are referred to as Insulators. Conversely, those with low resistivity or high conductivity values are called conductors while those with intermediate values are named semiconductors.
In the question given above, the material with a resistivity value of 3.2 × 10^8 - - - has a very high resistivity value (320000000Ω), the other options given have very low resistivity values ; 0.0000000017, etc and are most likely to be conductors due to their excessively low resistivity values.

Resistance and resistivity are related by a:
A: factor that is dependent on the length of the material
B: proportionality constant dependent on the source of the material
C: factor that is dependent on the area of the material
D: proportionality constant dependent on the identity of the material
Answer: D
Explanation: Resistance of current in a wire is directly proportional to the length of the wire and inversely proportional to the cross - sectional area of the wire. That is,
R = (rho × L)/A
Where
L = length of the wire
A = cross sectional Area of the wire
rho = resistivity = proportionality constant which depends on the quality of the wire.
Therefore, Resistance and resistivity are related by a:
proportionality constant dependent on the identity of the material.
