The average force vehicle experiences is 6000N.  The correct option is B.

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.

These types of organisms are classified as facultative aerobes.

In order to create energy from food, cells must engage in a process known as aerobic respiration, which occurs when there is an oxygen gas present.

An organism that uses anaerobic respiration to produce ATP is known as a facultative aerobes. Although these bacteria need oxygen to survive, they may also exist without it. Despite being able to exist in the presence of oxygen, some creatures do not require it. By fermenting, they produce ATP. Aerobic respiration is how they produce ATP.

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).

The antibiotic was effective only against the bacteria species that decreased or was eliminated, but ineffective against the population that increased.

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 was effective only against one of the bacteria species -the population that decreased or was eliminated- but ineffective against the other population.

Answer:

enzymes don't affect the free energy of the reactants or products

Explanation:

That is, they don't change whether a reaction is energy-releasing or energy-absorbing overall. That's because enzymes don't affect the free energy of the reactants or products. Instead, enzymes lower the energy of the transition state, an unstable state that products must pass through in order to become reactants.
