What is the KE of a 250kg cart as it reaches the bottom if it’s velocity was 22m/s?
Answer:
Kinetic energy = 60500 J
Explanation:
Given that,
Mass of the cart, m = 250 kg
Velocity of the cart, v = 22 m/s
We need to find the kinetic energy of the cart. This type of energy is possessed due to motion of an object. It can be given by :
[tex]E_k=\dfrac{1}{2}mv^2\\\\E_k=\dfrac{1}{2}\times 250\times (22)^2\\\\E_k=60500\ J[/tex]
So, the kinetic energy of the cart is 60500 J.
How do bacterial species build antibiotic resistance? Do viruses do the same thing?
Answer:
When bacteria develop fortifications against the antibiotics that are developed to eradicate them it is termed as antibiotic resistance. Antimicrobial resistance is not only applicable to bacteria, but it is also applicable to other germs like fungi or viruses. There are various ways by which bacteria develop confrontation against antibiotics.
Some bacteria are naturally resilient due to the nonexistence of the target that the antibiotic attacks or due to a remarkably impervious cell membrane. Some of the bacteria possess the tendency to generate enzymes, which can incapacitate antibiotics at the time of acquaintance. In some of the situations, bacteria can change the target of the antibiotics, making the antibiotic inefficient. The generation of efflux pumps in some of the bacteria makes antibiotics to get transport out of the bacterial cell.
The antibiotics are not efficient against viral infections like influenza, colds, bronchitis, the majority of sore throats, and many ear infections and sinuses. The widespread application of antibiotics for these illnesses can generate the spread of antibiotic resistance.
what is the result of too much or too little Dark energy:
Answer:
Dark Energy, Dark Matter
In the early 1990s, one thing was fairly certain about the expansion of the universe. It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. Granted, the slowing had not been observed, but, theoretically, the universe had to slow. The universe is full of matter and the attractive force of gravity pulls all matter together. Then came 1998 and the Hubble Space Telescope (HST) observations of very distant supernovae that showed that, a long time ago, the universe was actually expanding more slowly than it is today. So the expansion of the universe has not been slowing due to gravity, as everyone thought, it has been accelerating. No one expected this, no one knew how to explain it. But something was causing it.
Eventually theorists came up with three sorts of explanations. Maybe it was a result of a long-discarded version of Einstein's theory of gravity, one that contained what was called a "cosmological constant." Maybe there was some strange kind of energy-fluid that filled space. Maybe there is something wrong with Einstein's theory of gravity and a new theory could include some kind of field that creates this cosmic acceleration. Theorists still don't know what the correct explanation is, but they have given the solution a name. It is called dark energy.

A scientist has a hunch that students learn best when they write down information with a pencil or pen. He organizes his students into two groups. Half of his students use pencil use pencil or pen to take notes in class every day and the other half type their notes on their laptops. At the end of the unit, all the students take the test and he looks at their scores to determine the outcome of the experiment. What is the dependent and independent variable? 100 points!!!!
Answer:
The correct answer would be :
independent variable : use of pen or pencil
Dependent variable : test scores (test of learning ability)
Explanation:
Independent variable of any scientific investigation or experiment is a variable that is manipulated or changed to see the change in dependent variable. In this case the variable that is changed or manipulated is use of pen or pencil to see that effect on learning ability.
Dependent variable is something that is measured or calculated to find the effect of the independent variable. In this case the dependent variable is test score that will provide idea that if hunch of scientist is true or not.
Thus, the correct answer would be :
independent variable : use of pen or pencil
Dependent variable : test scores (test of learning ability)
Answer:
pens and pencils, a tablet or/calculator, his notes.

The function of the citric acid cycle is to transfer the acetyl group gained from glycolysis to molecules of pyruvate. hydrolyze glucose in the presence of oxygen to obtain two pyruvate molecules. remove hydrogen atoms from organic molecules and transfer them to coenzymes. produce water. produce carbon dioxide to balance the oxygen requirement for cellular respiration.
Answer:
The function of the citric acid cycle is to produce carbon dioxide to balance the oxygen requirement for cellular respiration.
Explanation:
In the citric acid cycle, pyruvate is first decarboxylated, leading to the production of CO₂, NADH, and the energy-rich substance acetyl-CoA. The acetyl group of acetyl-CoA then combines with the four-carbon compound oxaloacetate, forming the six-carbon compound citric acid. A series of reactions follow, and two additional CO₂ molecules, three more NADH, and one FADH are formed. Ultimately, oxaloacetate is regenerated to return as an acetyl acceptor, thus completing the cycle .

Aerobic cellular respiration generates about ______ ATP from one glucose. 2 6 36 The number generated depends on whether the end product of aerobic respiration is lactic acid or ethyl alcohol.
Answer:
The answer is 2.
Explanation:
I think there is a mistake in the question.
Aerobic respiration results in water and carbon dioxide as end products and it produces 38 ATP.
Anaerobic respiration, which does not require oxygen, results in either lactic acid or ethyl alcohol as end products and produces 2 ATP from a single glucose.

Which scenario would be most appropriate to study using a natural experiment? * the effects of an herbicide on human health the influence of sleep on exam performance the effects of an earthquake on blood pressure
Answer:
C. the effects of an earthquake on blood pressure
Explanation:
Natural experiments are observational studies in which participants are randomly assigned to groups that allow the researcher to draw causal relationships between an event and a factor. These experiments are used in studies where it would be unethical and unacceptable to subject human participants to such conditions. It is most times applied in epidemiological studies.
Since the researcher cannot control an earthquake which is a natural occurrence, this can be rightly described as a natural experiment. Controls are not used in this type of experiment.

Complete question: The chart shows the movement of a ball after several seconds.
Column A is on the x-axis, and Column B is on the y-axis. Which titles should replace A and B?
a. Column A should be “Time,” and Column B should be “Position.”
b. Column A should be “Position,” and Column B should be “Time.”
c. Column A should be “Velocity,” and Column B should be “Speed.”
d. Column A should be “Speed,” and Column B should be “Velocity.”
Answer:
Column A should be "Time," and Column B should be "Position"
Explanation:
In general, the first column always refers to the x-axis, this is the independent variables. While the second column refers to the y-axis, the dependent variables.
Option A) names Time and Position to the columns. This seems to be correct as time is an independent variable, while the ball position depends on time. The x-axes is named "time", and the Y-axes is named "ball position".
Option B) is not possible because the Position is not the independent variable, and time is not the dependent variable.
Option C) and D) are not possible, as both of them are variables that depend on time.
