Explanation:

The food chain consists of autotrophs (producers) and heterotrophs (consumers). All animals and plants fall into these categories.

The autotrophs are the first stage of the food chain. They are mostly plants. They use the radiation from the sun to fulfill their energy needs. In doing this process the autotrophs release oxygen. The process is known as photosynthesis. The plants take in carbon dioxide in the atmosphere released by heterotrophs during respiration and the plants in turn release carbon dioxide. Also, autotrophs provide a food source for the heterotrophs.

Every producer and consumer interact in some way, completing food chain.

Answer:

Scientists develop knowledge by making observations about the natural world that may lead to a scientific question

Explanation:

Science has been able to change history and develop some elemental theories that explain how everything works by following some steps. These steps are known as the "scientific method", which can be described as a systmatic way of learning about the world and answering questions. The most basic step that allow scientists to develop questions about something is the observation, by observing things doubts will emerge. This will lead to the next step that is asking questions. In this way your research problem will be more accurate and therefore easier to study. The following steps are: form an hypotesis, make a prediction based on the hypotesis and test the prediction.

Answer:

D. The universe

Explanation:

just got it correct

We may observe a sphere with a diameter of around 28 billion light years because the cosmos is enormous and has been expanding for about 13.8 billion years at a rate that is only a small fraction of the speed of light. Thus, option D is correct.

Even just exploring our galaxy would take countless millennia, let alone the entire universe. The Hyperion Supercluster galaxy supercluster is another old formation.

The largest and most numerous galaxy is the universe. A galaxy is a massive cluster of gas, dust, billions of stars, and their solar systems that are all bound together by gravity.

Therefore, No, every solar system and galaxy can be found in the cosmos. The Milky Way Galaxy contains hundreds of billions of stars, including our Sun, while the universe itself is made up of billions of galaxies.

Final answer:

The optimal month for Jim to plant coffee beans is June, before the snow season and during the warm, moist climate period. Climatic factors and temperature changes due to climate change should also be considered in planning for coffee production.

Explanation:

The best month for Jim to plant coffee beans on his farm, considering the climate requirements for coffee growth (warm, moist, and sunny conditions) and the pattern of snow from November, would be June. This period, just after the moderate temperatures from June to October, would offer the newly planted coffee trees the optimal window for warm temperatures before the cold, snowy conditions set in. It's important for Jim to avoid the snow season and capitalize on the warm and moist period for the plantation.

Moreover, climate change has been an increasing concern for coffee production globally. In regions like Colombia, rising temperatures and changes in precipitation have adversely affected coffee output, requiring the development of new agricultural methods. Jim should be aware of and prepared to respond to these challenges by considering shade-grown coffee and soil health management to potentially mitigate climate change impacts.

triple beam balance and meterstick

The set of instruments that would be helpful to determine the density of an object are triple beams balance and meterstick

Triple beam balance refers to an instrument that can be used to measure the mass of different objects. It is called triple beam balance because it is made up of three beams.  

Each of the beams has different weights and their size matches the gradations of the notched scale present on each of the beam. The size of the beams varies, the middle beam has the largest size, the far beam has a medium size and the font beam is the smallest size.

The basic parts of a triple beam include:

Also, meterstick can be helpful to determine the density of an object

Explanation:

Final answer:

The gravitational potential energy (G.P.E.) of a 675-newton climber at the top of a 3,050-meter mountain is calculated as 2,058,750 Joules.

Explanation:

To calculate the gravitational potential energy (G.P.E.) of a 675-newton climber at the top of a 3,050-meter mountain in Colorado, we use the formula G.P.E. = weight × height × acceleration due to gravity (g = 9.8 m/s²). Assuming that the weight given is the force due to gravity on the climber, the weight already accounts for the gravitational acceleration, so we do not need to multiply by 9.8 m/s² again. Therefore, the G.P.E. is simply the product of the weight and the height.

G.P.E. = 675 N × 3,050 m

G.P.E. = 2,058,750 Joules

Thus, the climber has a gravitational potential energy of 2,058,750 Joules at the top of the mountain.

Difference in air pressure

Humid air has lower air pressure because humid air contains lots of water. As more and more water enters the atmosphere it displaces other, heavier molecules. As a result air that is humid is much lighter. Since humid air is lighter, it has less weight to press down with so it has lower pressure.

Explanation:

Initial speed of the driver, u = 15 m/s

Acceleration of the driver, [tex]a=-2\ m/s^2[/tex]

Final speed of the driver, v = 10 m/s

Let t is the time taken by the driver to accelerate to the final speed. Using first equation of kinematics as :

[tex]t=\dfrac{v-u}{a}[/tex]

[tex]t=\dfrac{10-15}{-2}[/tex]

t = 2.5 seconds

Let d is the distance the car moved during the breaking period. Using the third equation of kinematics as :

[tex]v^2-u^2=2ad[/tex]

[tex]d=\dfrac{v^2-u^2}{2a}[/tex]

[tex]d=\dfrac{(10)^2-(15)^2}{2\times (-2)}[/tex]

d = 31.25 meters

Hence, this is the required solution.

Answer:

Law of conservation of mass.

Answer: To hit the target fish must spit with the velocity of 7.30 m/s.

Explanation:

Highest point of the trajectory = H = 2 m

Angle at which archer fish spit = θ = 60°

Acceleration due to gravity = g = 10 [tex]m/s^2[/tex]

The maximum height of the projectile is given as:

[tex]H=\frac{u^2\sin^2\theta }{2g}[/tex]

[tex]2 m=\frac{u^2\sin^2(60^o)}{2\times 10 m/s^2}[/tex]

[tex]\sin 60^o=\frac{\sqrt{3}}{2}[/tex]

[tex]u^2=\frac{2 m\times 2\times 10 m/s^2\times 4}{3}=53 m^2/s^2[/tex]

[tex]u=7.30 m/s[/tex]

To hit the target fish must spit with the velocity of 7.30 m/s.

To hit the target fish must spit with the velocity of 7.30 m/s.

Highest point of the trajectory = H = 2 m

Angle at which archer fish spit = θ = 60°

Acceleration due to gravity = [tex]g = 10 m/s^2[/tex]

The maximum height of the projectile is given as:

[tex]H=(u^2\sin^2\theta )/(2g)[/tex]

[tex]2 m=(u^2\sin^2(60^o))/(210m/s^2)[/tex]

[tex]\sin 60^o=\sqrt{(3)/(2)}[/tex]

[tex]u^2=(2 m \times2 10 m/s^2 4)/(3)=53 m^2/s^2[/tex]

u=7.30 m/s

Answer:

The amount of force and the angle between them.

Explanation:

TO solve this problem, we simply need to use ratio and proportion. From the statement problem we can say the ratio height : distance, so that: (let us say that X is the image distance)

15 cm : 30 cm = 10 cm : X

We know that the symbol : means division so:

15 cm / 30 cm = 10 cm / X

X = 10 cm * 30 cm / 15 cm

X = 20 cm

So the image distance is 20 cm
