When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If the object is slowing down, where is the energy going?
1. The potential would increase since when the ball is slowing down, its kinetic energy is being transformed into potential energy and when the ball gets hit or kicked again, it releases the potential energy and it transforms into kinetic energy.
2. The kinetic energy wouldn't exactly be lost to friction or air resistance, it's merely being converted into potential energy when the ball is slowing down due to those factors.
3. The ball returning to its natural resting state is correct since according to Newton's 1st Law in which an object that is at rest or is moving will not change unless there is another force acting upon it. in this case, the ball was kicked and there are other forces acting upon it like friction and air resistance, those factors cause the ball to slow down. Eventually the ball will stop and return to its original resting state.
4. This one is incorrect since kinetic energy is not staying the same as the person or any other force that is exerted on it be increased therefore increasing the kinetic energy.
A factory that has not followed pollution control standards has been operating in an area that did not have such a factory before. Plants that used to grow well are not doing well. Fish in a nearby river are dying at a higher rate than usual. Why?
A Pollution from the factory is getting into the rain, which is making the pH levels in the soil and water rise.
B It hasn't rained enough and the plants aren't getting enough water.
C The factory has increased the temperature in the area.
D Pollution from the factory is getting into the rain, which is making the pH levels in the soil and water become lower.
Answer:
D
Explanation:
If the pH levels are becoming low then the water and dirt becomes acidic killing fish and plants

Explain how your model demonstrated energy transformation from thermal energy to mechanical energy during a volcanic eruption.
(I mixed warm water, vinegar, and baking soda)
Answer:
Well to begin with, the thermal energy is mostly provided by the energy contained in warm water, when mixed with the other two components the chemical units are modified to form a composite solution that will result in an energy release, this energy release generate a movement, which in this case is the eruptive movement simulating the eruption of a volcano.
Explanation:
By mixing the vinegar (which is an acid) with the baking soda (which is a base), they react and transform into water, sodium acetate (a salt), and carbon dioxide (a gas). Carbon dioxide (CO2) is the gas that causes bubbles to form from the eruption of the volcano and balloons to swell.

Your teacher places the following supplies on a table: water, hot plate, salt, beakers, food coloring, and test tubes. Using the supplies listed, how could you plan an investigation of how differences in temperature and salinity affect ocean currents? Include the following vocabulary in your explanation: salinity, density, temperature, wind, surface currents, deep currents. Make sure to include specific details and steps.
Answer:
Higher saline water is more dense that lower saline water
Explanation:
The ocean salinity varies with rainfall, run off from estuaries and the pattern of ocean current. In addition to this, higher temperature affects the kinetic movement of water as well as the salinity. The movement of the wind also contributes to the movement of water and the particles and solute distribution. The surface currents do not do much to mix the entire body of water and this is because this is from less dense areas. Deep currents factor in to mix just the heavier more dense layers.
In planning an experiment to test this one would do two experiments.
First: Heat 4 batches of water at different temperatures and color the different temperatures with different food coloring. Next layer the water carefully from hottest to coldest in a beaker and then from coldest to hottest in another beaker.
Second: Dissolve salt in 4 batches of water increasing the amount by half each time. Color each with different food colouring and layer the salty water from least salt to most salt in a beaker. Layer the water from most salt to least salt in another beaker.
Make observations:
The cooler water should be more dense and sink to the bottom while the saltier water should be more dense and sink to the bottom.

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.
Answer:
E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.
Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.
Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.
When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.
Hence, the culture of bacteria carrying plasmid will be able to survive only.
Maximum transformation to tetracycline achieved when cells were harvested from L broth at 5.0-6.0 cfu/ml , followed by washing twice in cold.
The susceptibility of E.coli strain to culturing transformation by plasmid DNA was examined and optimized.
TransformationCells grown within the presence of D - cycloserine ( Cyc ) rather than Neg Gram (N x) transformed better. The presence of 5 mm Mg2+ ions in washing and CaCl2 solutions stimulated transformation about 2-fold.
Optimal conditions for transformation included a pH range of seven. 25-7.75 and a cell-to-DNA ratio of about 1.6 . 10(8) cfu/ng plasmid DNA.
The frequency of transformation was highest when cells were exposed to 100 mM CaCl2 in 250 mm.
Composition[tex]\rm KCl + 5 mM \;MgCl2 + 5 mM \;Tris[/tex]
pH 7.6, before mixing with DNA
Therefore, the results of culturing transformed E.coli within the presence of tetracycline is justified.

Explain why an increase in CO, in Earth's atmosphere, might cause the temperature of the atmosphere to increase and lead to climate change.
Answer:
When the carbon dioxide concentrations rise, the air temperature will rise as well due to the greenhouse gases heating up and multiplying.
Explanation:
Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapour accounts for about 50 percent; and clouds account for 25 percent. ... Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapour evaporates into the atmosphere—which then amplifies greenhouse heating.

How can scientists investigate the impact of limiting factors on a population?
Answer: No population can increase without limitation. Instead, populations in natural ecosystems increase or decrease in response to the changes in the factors that restrict growth. Many factors influence population densities and growth, and these factors may lead to oscillations in population size over time. It is also often difficult to determine the exact factor limiting growth. Many different factors may combine to produce unexpected results.
Explanation: I hope this helps....
Answer:
Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. Limiting factors determine the carrying capacity of a population.

I think there is life beyond earth. Actually there most definently is. I think in a way it could be limiting. It's the fcat that the ones out there may not even be able to receive the message as fast as we please. Who knows, it could be years, decades, maybe centuries before they make actual contact with us. Then again, maybe they already have. But, the way this could affect the study is the fact that (I doubt it) but maybe a message could be sent the wrong way, or they misinterpret it.

BY USING FOREST WISELY;
It was learnt that people are cutting trees at an worrying rate.This problem is disturbing because ;
1)Those trees are responsible for releasing of oxygen and they made up at least a quarter of the world population.
2) Those trees of the world make up of portion land species by more than forth or fifth portion.
There are also economic implications as a result of trees been cut down, when there is no availability bot trees , it could result to situation whereby there would be scarce of resources for industries as well as
hike price of paper in market, regardless of this trees are needed for manufacturing of important materials such as usage in making houses and others developments or growth
Therefore, all the afformentioned economic concern result in economics delay scientists' first attempts.
COMMUNITY CONSERVATION;
It was learnt that there is to the forest that those gorilla habitated, those human being that reside in those region reside there so they can practice their farming because their is available land there. They also reside there because of housing.
These gorillas were affected as a result of the destruction made to their habitat as well as the activities of the poachers that hunt them for production of the and skin.
There are adverse effect of the obliteration of the gorilla from on the society, it can result to having reduction in tourism in country such as
Uganda as well as Rwanda, as result of this the means of livelihood of people in that part could be affected because there would be Reduction in profit making. Hence the reason behind the increase in number gorillas in the region, because they know they know that those gorilla influence the number of tourist that comes there and the revenue that is generated through this tourism.
The article 'By using Forest Wisely' can be summarised as:
People are cutting trees at the wrong rate and trees play a crucial role in an ecosystem. The trees produce oxygen and they made up at least a quarter of the world population.The trees occupy the fourth or fifth portion of the land organisms.In the absence of trees, the ecosystem will fail and the organisms dependent on them will eventually die. The resources available from the trees will be scarce and the factories and industries that are dependent on trees will no longer be available. Trees are required for manufacturing important materials.The article 'Community Conservation' can be summarised as:
In the article, it was mentioned that the human populace urbanized the land region where gorillas were habituating. The humans occupied the space to practice farming and make houses. The population of the gorillas was disturbed and diminished. The hunting of gorillas by poachers was also reduced. The people of Uganda and Rwanda also suffered reduction tourism and conservation of wildlife. Gorillas influence the number of tourists, therefore, the destruction of their habitats led to a reduction in profit-making.Therefore, all the mentioned economic concerns result in economics delaying scientists' first attempts.
