Answer:
Relationship between population size, carrying capacity, and limiting factors is described below.
Explanation:
1. There are four variables which govern changes in population size.
births
deaths
immigration
emigration
A population gains individuals by birth and immigration and loses individuals by death and emigration.
2. Populations vary in their capacity to grow. The maximum rate at which a population can increase when resources are unlimited and environmental conditions are ideal is termed the population's biotic potential.
3. There are always limits to population growth in nature. Populations cannot grow exponentially indefinitely. Exploding populations always reach a size limit imposed by the shortage of one or more factors such as water, space, and nutrients or by adverse conditions such as disease, drought and temperature extremes.
4. The factors which act jointly to limit a population's growth are termed the environmental resistance. The interplay of biotic potential and density-dependent environmental resistance keeps a population in balance.
5. Carrying Capacity
For a given region, carrying capacity is the maximum number of individuals of a given species that an area's resources can sustain indefinitely without significantly depleting or degrading those resources. Determining the carrying capacities for most organisms is fairly straightforward. For humans carrying capacity is much more complicated. The definition is expanded to include not degrading our cultural and social environments and not harming the physical environment in ways that would adversely affect future generations.
6. Population Impact
Homo sapiens is a species possessing a diversity of individual needs. Thus, sub-populations will have different requirements and different impacts on the environment. For example 100 million vegetarians will have a significantly different environmental impact than 100 million meat-eaters. This can be demonstrated by comparing the affect on water supplies by both sub-populations. About 1000 tons of water are needed to produce 1 ton of grain. Almost 40% of all grain is used in meat and poultry production. Add to this the amount of water that goes into the production of meat, and you can see that meat comsumption places more stress on global water supplies than grain consumption.

During a baseball game, a batter hits a high
pop-up.
If the ball remains in the air for 5.93 s, how
high above the point where it hits the bat
does it rise? Assume when it hits the ground
it hits at exactly the level of the bat. The
acceleration of gravity is 9.8 m/s
2. Answer in units of m.
Answer: 43.01 m
Explanation:
Given that :
Time ball uses in the air = 5.93, time it takes to reach maximum height and return = time of flight(T) = 5.93 s
TIME of flight (T) = 2 * time taken(t)
Where g = a = acceleration due to gravity = 9.8m/s²
S = 0.5at²
S = maximum height
Tjme taken (t) = time of flight / 2 = 5.93/2 = 2.965 s
Hence,
S = 0.5at²
S = 2 × 0.5 × 9.8 × 2.965²
S = 43.0770025
S = 43.01 m

(Write a paragraph) What are the similarities and differences between these volcanoes:
Composite Volcano, Lava Dome, Shield Volcano, and Cinder Cone.
Answer:
Explanation:
Composite volcanoes, also called stratovolcanoes, are cone-shaped volcanoes built from many layers of lava, pumice, ash, and tephra. A lava dome is a circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. A shield volcano is a type of volcano usually composed almost entirely of fluid lava flows. It is named for its low profile, resembling a warrior's shield lying on the ground. A cinder cone is a steep conical hill of loose pyroclastic fragments, such as either volcanic clinkers, volcanic ash, or cinder that has been built around a volcanic vent.

A group of students prepare for a robotic competition and build a robot that can launch large spheres of mass M in the horizontal direction with variable speed and from a variable vertical position and a fixed horizontal position x=0.
The robot is calibrated by adjusting the speed at which the sphere is launched and the height of the robot’s sphere launcher. Depending on where the spheres land on the ground, students earn points based on the accuracy of the robot. The robot is calibrated so that when the spheres are launched from a vertical position y=H and speed v0, they consistently land on the ground on a target that is at a position x=D. Positive directions for vector quantities are indicated in the figure.
When the students arrive at the competition, it is determined that the height of the sphere launcher can no longer be adjusted due to a mechanical malfunction. Therefore, the spheres must be launched at a vertical position of y=H2. However, the spheres may be launched at speed v0 or 2v0.
Question: In a clear response that may also contain diagrams and/or equations, describe which speed, v0 or 2v0, the students should launch the sphere at so that they earn the maximum number of points in the competition.
Answer:
[tex]V_0[/tex]
Explanation:
Given that, the range covered by the sphere, [tex]M[/tex], when released by the robot from the height, [tex]H[/tex], with the horizontal speed [tex]V_0[/tex] is [tex]D[/tex] as shown in the figure.
The initial velocity in the vertical direction is [tex]0[/tex].
Let [tex]g[/tex] be the acceleration due to gravity, which always acts vertically downwards, so, it will not change the horizontal direction of the speed, i.e. [tex]V_0[/tex] will remain constant throughout the projectile motion.
So, if the time of flight is [tex]t[/tex], then
[tex]D=V_0t\; \cdots (i)[/tex]
Now, from the equation of motion
[tex]s=ut+\frac 1 2 at^2\;\cdots (ii)[/tex]
Where [tex]s[/tex] is the displacement is the direction of force, [tex]u[/tex] is the initial velocity, [tex]a[/tex] is the constant acceleration and [tex]t[/tex] is time.
Here, [tex]s= -H, u=0,[/tex] and [tex]a=-g[/tex] (negative sign is for taking the sigh convention positive in [tex]+y[/tex] direction as shown in the figure.)
So, from equation (ii),
[tex]-H=0\times t +\frac 1 2 (-g)t^2[/tex]
[tex]\Rightarrow H=\frac 1 2 gt^2[/tex]
[tex]\Rightarrow t=\sqrt {\frac {2H}{g}}\;\cdots (iii)[/tex]
Similarly, for the launched height [tex]2H[/tex], the new time of flight, [tex]t'[/tex], is
[tex]t'=\sqrt {\frac {4H}{g}}[/tex]
From equation (iii), we have
[tex]\Rightarrow t'=\sqrt 2 t\;\cdots (iv)[/tex]
Now, the spheres may be launched at speed [tex]V_0[/tex] or [tex]2V_0[/tex].
Let, the distance covered in the [tex]x-[/tex]direction be [tex]D_1[/tex] for [tex]V_0[/tex] and [tex]D_2[/tex] for [tex]2V_0[/tex], we have
[tex]D_1=V_0t'[/tex]
[tex]D_1=V_0\times \sqrt 2 t[/tex] [from equation (iv)]
[tex]\Rightarrow D_1=\sqrt 2 D[/tex] [from equation (i)]
[tex]\Rightarrow D_1=1.41 D[/tex] (approximately)
This is in the [tex]3[/tex] points range as given in the figure.
Similarly, [tex]D_2=2V_0t'[/tex]
[tex]D_2=2V_0\times \sqrt 2 t[/tex] [from equation (iv)]
[tex]\Rightarrow D_2=2\sqrt 2 D[/tex] [from equation (i)]
[tex]\Rightarrow D_2=2.82 D[/tex] (approximately)
This is out of range, so there is no point for [tex]2V_0[/tex].
Hence, students must choose the speed [tex]V_0[/tex] to launch the sphere to get the maximum number of points.
Free fall motion is motion in which the only force acting on the body is gravity
The student should launch the sphere at 2·v₀, for the sphere will land at approximately 1.41·D, which is in the 3 point zone
The given parameter are;
The distance covered by the sphere when launched at height, H = D
The velocity with which the ball reaches D = v₀
The current available height of launcher= H/2
The available velocities = v₀, and 2·v₀
Solution:
From H = u·t + (1/2)·g·t², where, initial velocity of the vertical motion of the ball, u = 0 we have;
H = (1/2)·g·t²
∴ The time it takes the ball to drop from H, t = √(2·H/g)
The distance, D = v₀ × √(2·H/g)
When the height is H/2, we get;
t = √(2·H/(2·g)) = √(H/g)
The distance covered, D₁ = v₀ × √(H/g)
Therefore, D = (√2) × v₀ × √(H/g) = (√(2))·D₁
D₁ = D/(√2) ≈ 0.71·D
D₁ ≈ 0.71·D
At speed 2·v₀, we have;
D₂ = 2·v₀ × √(H/g) = √2 × v2 × v₀ × √(H/g) = √2 × v₀ × √(2·H/g) = √2·D₁ ≈ 1.41·D
D₂ ≈ 1.41·D
The 2 point zone = D/2 < x < D = 0.5·D < x < D (Position D₁ ≈ 0.71·D is located here)
The 3 Point Zone = D < x < 3·D/2 = D < x < 1.5·D (Position D₂ ≈ 1.41·D is located here)
Given that at D₂, the ball lands in the 3 Point Zone, the student should launch the sphere at the speed, 2·v₀, so that the ball will land at D₂ ≈ 1.41·D, which is in the 3 Point Zone

What is ratio?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7).
A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations.
Let, sea level is x meter below the submarine in the model.
According to the question:
x: 1000 =1:500
x/1000 = 1/500
x = 1000/500
x = 2

To win the game, a place kicker must kick a
football from a point 52 m (56.8672 yd) from
the goal, and the ball must clear the crossbar,
which is 3.05 m high. When kicked, the ball
leaves the ground with a speed of 26 m/s at
an angle of 31.5◦ from the horizontal. The acceleration of gravity is 9.8 m/s2.
By how much vertical distance does the ball clear the crossbar?
Answer in units of m.
Answer:
1.86 m
Explanation:
First, find the time it takes to travel the horizontal distance. Given:
Δx = 52 m
v₀ = 26 m/s cos 31.5° ≈ 22.2 m/s
a = 0 m/s²
Find: t
Δx = v₀ t + ½ at²
52 m = (22.2 m/s) t + ½ (0 m/s²) t²
t = 2.35 s
Next, find the vertical displacement. Given:
v₀ = 26 m/s sin 31.5° ≈ 13.6 m/s
a = -9.8 m/s²
t = 2.35 s
Find: Δy
Δy = v₀ t + ½ at²
Δy = (13.6 m/s) (2.35 s) + ½ (-9.8 m/s²) (2.35 s)²
Δy = 4.91 m
The distance between the ball and the crossbar is:
4.91 m − 3.05 m = 1.86 m
