Answer:
Carbon
Explanation:
Carbon is one of the fundamental element that is present in organic compounds. The presence of carbon helps in the creation of a stable type of bond when combines with different elements. Two carbons can also form a bond by reacting with each other. So, it can create a larger and complex form of molecules. These compounds containing carbon are important as it carries out the various life-supporting processes.
This is why Carbon is very essential for the existence of life.

Why do some environmental groups oppose tidal energy?
Answer:
Environmental groups oppose tidal energy because of the following potential negative consequences:
By changing the flow of tides with dams, there can be negative impact on the aquatic shoreline of the ecosystem;building of barrages may affect the sedimentation and turbidity of water within water basinsthere are animals what depend on the flow of tides for existence feeding and movement. The techology which captures the energy produced by the ties and converts them to electricity may affect the natural flow fo the tides thus impactin negatively on the aquatic and non-aquatic habitat.Cheers!
Calculate the G.P.E. in joules of a 675-newton climber at the top of a 3,050-meter mountain in Colorado.
Answer:2673
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.

a driver of a car traveling at 15.0m/s applies the brakes, causing a uniform acceleration of -2.0m/s^2. how long does it take the car to accelerate to a final speed of 10.0m/s? how far has the car moved during the breaking period?
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.
[BWS.02] Jim plans to plant coffee beans on the farm. Coffee needs warm, moist, and sunny climate. It always snows for four months, starting from November, in the location where Jim lives. The temperature is generally moderate from June to October. Based on scientific knowledge, which of these would be the best month to plant coffee?
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.
To determine the density of an object, which set of instruments would be helpful?
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.
Further ExplanationEach 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:
Weight pan: the object to be weight is placed on the weight panBase: the base is beneath the weight pan and can be set up to properly fit on the workbenchBeam: the beams can be used to get the level of precisionRiders: they are on top of the beams and indicates the mass (g) of an objectPointers: the pointer marks the mass of the object on the scaleZero adjustment knob: the knob are used to set the beam balance to zero marks before useAlso, meterstick can be helpful to determine the density of an object

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.
What Milky Galaxy, is very small compared to the Universe?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.

An object 15cm high is 30cm from a pinhole camera.if the height of the image formed at the back of the camera is 10cm,the image distance is?
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

Two locations have different water vapor content in their atmosphere. Which of these is likely to be recorded?
Difference in rates of runoff
Difference in air pressure
Same humidity levels
Same temperature
Difference in air pressure
Explanation: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.
How do consumers sometimes interact with producers?
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.
