A 2000kg vehicle travelling 30m/s takes 10s what force did the vehicle experience
A.-7000 km•m/s2
B.-6000km•m/s2
C. -5000km•m/s2
D.-8000km•m/s2
The average force vehicle experiences is 6000N. The correct option is B.
What is Newton's second law of motion?It states that the force F is directly proportional to the acceleration a of the body and its mass.
F =ma
Given is a 2000kg vehicle travelling 30m/s takes 10s.
It takes t = 10s to come to rest, then the acceleration will be
a = velocity /time
a = 30/(10)
a = 3 m/s²
According to the Newton's second law of motion.
F = 2000 kg x 3 m/s²
F =6000 N
Thus, the average force vehicle experiences is 6000N.

Two cultures, each containing a different species of bacteria, were exposed to the same antibiotic. explain how, after exposure to this antibiotic, the population of one species of bacteria could increase while the other population of the other species of bacteria decreased or was eliminated. *
The antibiotic was effective only against the bacteria species that decreased or was eliminated, but ineffective against the population that increased.
What are antibiotics?
When talking about antibiotics we refer to drugs or medicine used to treat infections caused by bacteria. They act to impede bacteria reproduction and eliminate them.
Antibiotics only act on bacteria, not viruses or other microorganisms, which means that they will only have an effect on affections caused by bacteria.
Also, not any antibiotic can be used to treat any bacterial affection. The antibiotic that must be used depends on the bacteria species. Each bacteria has its own properties, and hence, they respond to different drugs.
Antibiotics are grouped according to their chemical structure, properties, action spectrum, and the type of bacteria they attack.
According to this information, since each antibiotic is effective only against certain bacteria, we could assume that,
the antibiotic used in the experiment did not have any effect on the population of bacteria that could increase
the antibiotic was effective against the other bacteria species, causing its population to decrease or be eliminated.
The antibiotic was effective only against one of the bacteria species -the population that decreased or was eliminated- but ineffective against the other population.

Explain how the development of agriculture and the green revolution both affected humans. then explain how agriculture and the green revolution affected the environment. please be detailed in your response and write in complete sentences for full credit.
Answer:
The Green Revolution involved the widespread use of chemicals in agriculture that had adverse environmental impacts. The interrelationships between water resources, erosion, pesticides and fertilizers, deforestation, population pressure, and biodiversity, and farmers are individually addressed.
Explanation:
The development of agriculture and the green revolution affected humans by increasing food production. However, it also led to environmental degradation.
What is green revolution?The development of agriculture provided humans with a stable food supply and allowed for the growth of civilizations. It also led to the domestication of animals and the creation of farming communities. The Green Revolution, which began in the mid-20th century, involved the development and implementation of new agricultural technologies and increased the productivity of crops, leading to increased food production and economic growth in many countries.
However, the use of pesticides and fertilizers in agriculture has had negative impacts on the environment, including soil degradation, water pollution, and loss of biodiversity. The Green Revolution also resulted in the increased use of mechanized farming, which led to the loss of natural habitats and the displacement of wildlife.
Climate change caused by agricultural practices, such as deforestation, and the use of fossil fuels in farming, has also had a significant impact on the environment.

Select the correct answer from each drop-down menu.
Earth's atmosphere helps to regulate its temperature. However, the addition of gases such as
causes more energy to radiate back
toward Earth. As a result, the atmospheric temperature increases over time.
If Earth had no atmosphere, it would radiate nearly as much energy as it receives from the Sun. This implies that the temperatures on Earth would
be
Earth's current temperature.
Answer:
Carbon dioxide; lower than.
Explanation:
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
Radiation is simply the transmission or emission of energy in the form of particles or electromagnetic waves through a vacuum, material medium or space.

Earth’s global average temperature is 14°C. Explain one change that can be made in this sim, that will dramatically increase the temperature.
Answer:
This graph illustrates the change in global surface temperature relative to 1951-1980 average temperatures. Nineteen of the hottest years have occurred since 2000, with the exception of 1998, which was helped by a very strong El Niño. The year 2020 tied with 2016 for the hottest year on record since record-keeping began in 1880 (source: NASA/GISS). This research is broadly consistent with similar constructions prepared by the Climatic Research Unit and the National Oceanic and Atmospheric Administration.
The time series below shows the five-year average variation of global surface temperatures. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average.
The “Global Temperature” figure on the home page dashboard shows global temperature change since 1880. One gets this number by subtracting the first data point in the chart (-0.16°C) from the latest data point (0.85°C).
