4. What factors contribute to a random distribution pattern? Why do animals
not maintain this distribution pattern year round?
1
Answer:
Random distribution may result when resources are equally distributed and are not scarce. As breeding brings individuals together, random distribution is not maintained year round.
When resources are readily available and evenly distributed, random distribution may occur. The random dispersion of individuals is not maintained year-round, since breeding brings people together.
What contribute random distribution pattern in animals?In environments with stable resources and environmental circumstances, random dispersion typically occurs. This pattern of dispersion is unique in that there are no substantial social contacts between species.
On land and in the water, animals are not equally dispersed. Climate zones or in all the confinements is known as Continuous Distribution, and such species of animals are known as Eurytopic Animals.
They are constrained to certain locations by a number of criteria such as food, shelter, and climate.
Therefore, The absence of any significant social interactions between species is what distinguishes this pattern of dispersion.

How can we transfer a table of motion data into a line graph?
Answer:
A table of motion (for a moving object) usually is something like:
Time I Position:
0s 1m
1s 3m
2s 5m
etc...
Where time is the independent variable and position represents the position of the object at that given time.
We can think in these points as coordinate pairs, for example, we can wrote these 3 pairs as:
(0s, 1m)
(1s, 3m)
(2s, 5m)
Now that we have these points, we can go to a coordinate plane and find these points
(The time would be on the horizontal axis, and position in the vertical axis)
Once you found the points, to complete the graph you need to find a line that connects the points.
An example of this is shown below, where the points used are the ones above, and the line should be straight.
Shuffling your feet across the floor as you walk is an example of
A) charging by friction
B) induction
C) static discharge
D) conduction
E) none of the above
Answer:
i think a
Explanation:
Shuffling your feet across the floor as you walk is an example of charging by friction. The correct option is A.
What is friction?The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction.
There are various kinds of friction: Two solid surfaces in touch are opposed to one another's relative lateral motion by dry friction.
Frictional force is the force produced when two surfaces slide against and touch each other.
The surface texture and amount of force needing them together have the biggest an impact on these forces. The amount of frictional force is influenced by the object's position and angle.
As an illustration of how charge is transferred via friction, consider walking over a carpet.
Thus, the correct option is A.

A rocket ship starts from rest and turns on its forward booster rockets causing it to have a constant acceleration of 4 meters per second rightward
Complete question is;
A rocket ship starts from rest and turns on its forward booster rockets, causing it to have a constant acceleration of 4 m/s² rightward. After 3s, what will be the velocity of the rocket ship?
Answer:
v = 12 m/s
Explanation:
We are given;
Initial velocity; u = 0 m/s (because ship starts from rest)
Acceleration; a = 4 m/s²
Time; t = 3 s
To find velocity after 3 s, we will use Newton's first equation of motion;
v = u + at
v = 0 + (4 × 3)
v = 12 m/s

Explanation:
Which diagram has a greater gravitational force
Answer:
2
Explanation:
Due to the fact that the gravitational force is inversely proportional to the mass of the two interacting objects, heavier objects will be drawn together by a stronger gravitational attraction. As a result, the gravitational pull between two objects grows as their respective masses rise.
What mass has a greater gravitational force?Since the gravitational force is exactly proportional to the mass of both interacting objects, heavier items will be attracted by stronger gravitational forces. Therefore, the gravitational attraction between two objects grows as their respective masses do as well.
The attraction created by gravity is between masses. The gravitational force, commonly known as the gravity force, increases with the size of the masses. With an increase in the distance between masses, the gravitational pull rapidly lessens.
Therefore, second have greater gravitational force.

A wire of resistance R is cut into ten equal parts which are then connected in parallel. The equivalent resistance of the combination is
Answer:
The equivalent resistance of the combination is R/100
Explanation:
Electric Resistance
The electric resistance of a wire is directly proportional to its length. If a wire of resistance R is cut into 10 equal parts, then each part has a resistance of R/10.
Parallel connection of resistances: If R1, R2, R3,...., Rn are connected in parallel, the equivalent resistance is calculated as follows:
[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+...+\frac{1}{R_n}[/tex]
If we have 10 wires of resistance R/10 each and connect them in parallel, the equivalent resistance is:
[tex]\displaystyle \frac{1}{R_e}=\frac{1}{R/10}+\frac{1}{R/10}+\frac{1}{R/10}...+\frac{1}{R/10}[/tex]
This sum is repeated 10 times. Operating each term:
[tex]\displaystyle \frac{1}{R_e}=\frac{10}{R}+\frac{10}{R}+\frac{10}{R}+...+\frac{10}{R}[/tex]
All the terms have the same denominator, thus:
[tex]\displaystyle \frac{1}{R_e}=10\frac{10}{R}=\frac{100}{R}[/tex]
Taking the reciprocals:
[tex]R_e=R/100[/tex]
The equivalent resistance of the combination is R/100
