If the two objects are dropped at 1.0 s time interval, their velocity will increase as they descend which will cause their separation distance to increase because velocity is directly proportional to displacement.
The rate at which each object falls is influenced by their respective weights. If air resistance is negligible, gravity will continue to pull each object until it hits the ground.
The influence of gravity will cause the following:
The speed of each object will increase gradually until it hits the ground, and each object will have maximum velocity before it hits the ground. This shows that velocity of each object increases as it descends.Velocity is directly proportional to displacement, as the velocity of each object increases, the distance between them will also increase.Thus, if the two objects are dropped at 1.0 s time interval, their velocity will increase as they descend which will cause their separation distance to increase because velocity is directly proportional to displacement.

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.

[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.

Two examples of renewable energy resources
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.

A) Balanced forces do not affect an object's motion. B) Unbalanced forces do not affect an object's motion. C) Balanced forces do affect an object's motion by changing its position. D) Unbalances forces do affect an object's motion by changing its position.
3) A defense football player on one team tackles the other team’s quarterback, who is running down the field. The quarterback is pushed to the ground by the defensive player. 4) apply Newton’s first law to explain what happened?
The force generated by the defensive player has more magnitude and as such would push the quarterback to the ground.
A force can be defined as a push or pull of an object (body), which typically results in a change of motion due to the interaction of the object (body) with another.
Newton's First Law of Motion is also referred to as Law of Inertia and it states that an object (body) in motion would continue in its state of motion at a continuous velocity (in the same speed and direction) or if at rest, it will remain at rest unless it is acted upon by an external force.
In this context, an unbalanced force is generated by the quarterback and the defensive player, but the defensive player's force is an external force with more magnitude and as such would push the quarterback to the ground.
According to Newton's First Law of Motion, the quarterback was pushed to the ground due to an external force, generated by the defensive player.

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

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.

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.
