The answer
the speed of <span>the train traveling in kilometers per minute can be found by using the following method:
v = </span><span>30 miles per hour
</span><span>1 mile = 1.6 kilometers
just do the calculus by changing miles to kilometers
</span>1 mile = 1.6 kilometers, so 30 miles= 1.6 km x 30 = 48 km
so the speed of the train is
v=30 miles / hour = 48km / h = 48km / 60 mn = 0.8 km/ mn
the answer is
<span>C- 0.8 km/min</span>
Answer:
C - raising the temperature of a gas
Explanation:
as you raise temperature, kinetic energy rises, and so does pressure
Answer:
<em>The correct option is B) a gradual change of the traits of a species over time</em>
Explanation:
The theory of natural selection explains the gradual changes which occur in the population of a species over time. According to natural selection, those organisms which are better adapted to live in an environment survive and pass on their traits to their offsprings. As a result, the traits of a species tend to change over time through the process of evolution. Evolutionary changes do not occur rapidly, instead, they can take many years to occur.
Answer:
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al2O3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
Water can be understood as both yin and yang. The number of ways Yin and Yang can be explained is in numerous ways.
Yin and Yang explain how to exist in harmony and in balance with nature. Yin and Yang are not distinct entities, but rather two extremes of a spectrum. Everything Yin includes a trace of Yang. Also, everything Yang contains a trace of Yin. They are always in connection with one another.
The yin is the physical aspect of nature and the yang is the forces surrounding these physical aspects.
Some of the ways in which Yin and Yang can be explained are as follows:
- Yin and Yang can be explained from the water, whereby the water is the Yin while the wind carrying the water waves is known as the Yang.
- In the body, the Yin shows the anatomy and structure of the body while the Yang explains the psychological functioning of the body.
Disruption in either Yin or Yang can cause an imbalance in nature.
Therefore, we can conclude that the number of ways in which we can explain the Yin and the Yang is numerous.
