The patterns that can be looked for when studying science topic include the use of data or carrying out an experiment.

<h3>How to illustrate the information?</h3>

It should be noted that patterns are regular and intelligible forms or sequences that can be found in nature. Based on the information, scientific questions may be generated when scientists want to observe a pattern of events.

It should be noted that when scientists want to observe a pattern of events or

when something does not match an established pattern, scientists can use patterns to classify objects or phenomena into groups.

Therefore, the patterns that can be looked for when studying science topic include the use of data or carrying out an experiment.

What is the period of a wave with a frequency of 100 Hz and a wavelength of 2.0 m

spin [16.1K]

The answer for the following answer is answered below.

Therefore the time period of the wave is 0.01 seconds.
Therefore the option for the answer is "B".

Explanation:

Frequency (f):

The number of waves that pass a fixed place in a given amount of time.

The SI unit of frequency is Hertz (Hz)

Time period (T):

The time taken for one complete cycle of vibration to pass a given point.

The SI unit of time period is seconds (s)

Given:

frequency (f) = 100 Hz

wavelength (λ) = 2.0 m

To calculate:

Time period (T)

We know;

According to the formula;

f = $\frac{1}{T}$

Where,

f represents the frequency

T represents the time period

from the formula;

T = $\frac{1}{f}$

T = $\frac{1}{100}$

T = 0.01 seconds

Therefore the time period of the wave is 0.01 seconds.

Talja [164]

Answer:

130.5

Explanation:

According to the stemplot attached (Which I think it is, and if not, then you only need to replace the procedure with your data and you should be fine), you need to calculate first the points of all ten students. In that plot, we can easily calculate the points.

The first number in the colum represents the centen of the point, while the numbers of the second column, represents the units of that centen, for example if you see:

16 | 8 5 6

This means that the point for the students are 168, 165 and 166. Three students, three points.

If you watch the stemplot, the points for the students are:

116, 118, 121, 124, 128, 133, 137, 142, 146 and 179.

The median can be calculated using the mean between the two values in the middle of the sequence.

In this case, half of ten is 5, so, the numbers from the middle in this sequence are 128 and 133, therefore:

Median = 128 + 133 / 2 = 130.5

Answer:

Explanation: The two main types of nuclear power are nuclear fusion and fission. Nuclear fission is used in nuclear power plants to create elements. Nuclear fission works by having a stray neutron collide with a nucleus. When this happens, it breaks the nucleus up, and another nuclei collides with another nucleus. A chain reaction occurs as this process continues. I personally think this type of nuclear power is dangerous because the result is radioactive byproducts. Also, meltdowns can occur in a nuclear power plant as a result of nuclear fission. I think nuclear fusion would be a much safer energy source. It is cheap and practically unlimited. Nuclear fusion occurs when two nuclei fuse together to create a larger nucleus. Nuclear fusion also proves Albert Einstein's equation E=mc2. The element you start out with is greater than the element you end up with after fusion occurs. This is due to some of the matter actually being converted into energy, which agrees with Einstein's equation. I think nuclear fusion is a safer energy source because it does not create radioactive byproducts that can be potentially harmful. Nuclear fusion, however, is not understood that well by scientists. As a result, we continue to use nuclear fission because we know how to use it. Until scientists fully understand nuclear fusion, scientists will continue to use nuclear fission for energy sources.

Pie

Galileo's discovery shows that, to an observer on Earth, Venus has phases just like Earth's moon. This observation provide support for the heliocentric model of the solar system as follows:

Galileo noticed the Moon is not flat, but rocky and rugged-just like the Earth did.
He used his telescope to observe the Venus phases. Galileo's findings confirmed his confidence in the concept of Copernicus that Earth and remaining planets revolve around the Sun, i.e. Heliocentrism.
While most individuals in Galileo's days assumed that the Earth was the center of the universe and that the Sun and planets revolved around it, i.e. geocentrism.
The idea of geocentric was generally preferred by the prominent and strong Catholic Church, and when Galileo started writing papers on his belief in a heliocentric with a valid explanation, he was called to Rome to face the inquisition's charges towards him.
Thus in early 1616 he was accused of being a heretic, but later he cleared of charges of "heresy" with warning that he should not spread his belief.
But he pursued his astronomy research, and was increasingly confident that all planets revolved around the Sun. Therefore he published a book in 1632 which explained that Copernicus' heliocentric theory was appropriate.
Thus after this finally he was charged by "heresy" and sentenced to life imprisonment in 1633, but due to his poor health he lived imprisonment under house arrest and finally died on January 8, 1642.
