In a paragraph, explain what the story of the Gadarene demoniac teaches us about our life in Christ.
GarryVolchara [31]

Answer:

Just like the previously possessed man told people about his new life in Christ, we, too, should share about our new life in Christ.

Explanation:

    The story of the demonaic is about a possessed man whose unclean spirits were sent out by Jesus. The spirits were sent into the pigs of the people who raised them to sell for profit (some of which were the Jew's pigs,) and they ran off the cliff and drowned. The owners of these pigs knew that Jesus did it to save the man but still were mad and wanted nothing to do with Jesus. They told Him to leave even though He saved the possessed man who they had previously tried to help. The man wanted to travel with Jesus, but He told the healed man to depart from Him and go to the people and share his story and how Jesus helped Him, and he obeyed. Just like the previously possessed man told people about his new life in Christ, we, too, should share about our new life in Christ.

    Hope this helps. Don't hate me if it's wrong but this is what I found.

9. Calculate the standard enthalpy of the 3rd reaction using the given data: A,H° = +52.96 kJ/mol AFH= -483.64 kJ/mol H2s)+I202
Mice21 [21]

Answer:

-586.56 kJ/mol is the standard enthalpy of the 3rd reaction.

Explanation:

H_2(g) +I_2(s) \rightarrow 2 HI(g) ,\Delta H^{o}_{1}= +52.96 kJ/mol...[1]

2 H_2(g) + O_2(g)\rightarrow 2 H_2O(g),\Delta H^{o}_{2}=-483.64 kJ/mol...[2]

4 HI(g)+O_2(g)\rightarrow 2 I_2(s)+2 H_2O(g) ,\Delta H^{o}_{3} =?..[3]

The unknown standard enthalpy of third reaction can be calculated by using Hess's law:

The law states that 'the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps'.

[2] - 2 × [1] = [3]

O_2+4HI\rightarrow 2H_2O(g)+2I_2(s)

\Delta H^{o}_{3}=\Delta H^{o}_{2}-2\times \Delta H^{o}_{1}

=-483.64 kJ/mol - 2\times (52.96 kJ/mol)=-586.56 kJ/mol

The standard enthalpy of the 3rd reaction is -586.56 kJ/mol.The negative sign indicates that energy is released during this reaction.

The first four planets in our solar system are rocky. How does that relate to Newton’s law of universal gravitation?
Serhud [2]

Explanation:

According to Newton law of gravity, the strength of gravitational pull between two objects is related to their masses, directly, and inversely by the distance between them;

F = G * (M₂ – M₁) / d where;

F – the force of gravity

G – gravitational constant

M₂ – the mass of one object

M₁ – the mass of the other object

d – the distance between the two objects

The rocky planets have a higher mass than the gas planets hence will be strongly ‘feel’ the gravitational pull of the star in the solar system revolves about.  This is why rocky planets are closer to their star while gas planets are towards the outer edges.

Describe the relationship between frequency and wavelength in your own words
Montano1993 [528]
Are frequency and wavelength the same thing? No, they are not the same but each is mathematically related to the other. Effectively, the wavelength is the distance between one wave peak and the next wave peak, or in other words, the distance between one wave high point and the next high point. Alternatively it could of course be said that wavelength is the distance between one wave low point and the next wave low point, but lets not get pedantic about it.

Think of waves in the ocean where a person may be observing the top of one wave and the top of the next wave. The wavelength is the distance between these two wave tops, or peaks. With waves in the ocean, the frequency of the waves will be the number of times that a wave peak crosses any given point on the ocean. It is probably easiest to measure frequency of waves from the ocean by standing on the beach and counting how many waves come up on the sand relative to any given time frame. Frequency is typically measured in how many waves per second but with ocean waves we are better to measure how many waves per minute because naturally the frequency will be less than one per second.

There is actually quite a bit of science over how ocean waves travel around our planet because high and low tide in the ocean are created by the moon. There is a theory that the moon creates waves that have a wavelength equal to half of the circumference of planet Earth. This is because there is a high tide at Earths point that is closest to the moon and then another high point that is at the greatest distance from the moon. The problem is that to keep up with the moon one needs to travel around the Earths equator at about 1800 kph, which is impractical for an ocean wave because they quite simply cannot travel at that fast a speed or velocity (technically angular velocity). This is what causes ocean waves to become so messy at times.

When discussing waves, most people are most comfortable discussing electromagnetic waves because almost all communication systems relied on in modern society are based on these waves and their frequency. When collecting electromagnetic waves, like TV waves, for example, there are several components to the antenna. One of them will typically have a loop of metal, which is where the required energy waves (carrying the required signal) are picked up or collected by the antenna. Don’t worry about the other components of the antenna because most are there simply to remove unwanted background waves that may spoil the quality of the signal that we collect. With the TV antenna, the distance across this “collection loop” is the wavelength that the antenna is tuned to collect.

The reason for a loop on the piece of metal that collects TV waves, rather than using a straight piece of wire, is so that all wavelengths that are close to the required one, will be collected. To get slightly more technical, in modern systems we have “frequency modulation”, which is what FM stand for. This means we deliberately make minor adjustments to the precise frequency, but I better not go into that.

The frequency of a TV wave that is being collected is the number of times in any time frame, that a wave front or wave peak, will cross the collection point. With typical electromagnetic waves like TV waves, we use a frequency that is measured to be so many Hertz. The Hertz is the standard measure of such things and it is equal to a number of wavelengths per second. The reason for this is that electromagnetic waves travel at the speed of light, which is incredibly fast.

If we are talking in the old fashioned “long wave” AM radio waves, then the wavelength is often several hundred metres in length. In Melbourne, Australia, the nearest large city to my home, the government owned ABC used a frequency of 774 kHz for many decades. They still do in fact, although most people tuned in probably rely on a repeater station these days and these will broadcast in a higher frequency. 774 kHz is a frequency of 774 thousand cycles per second. This sounds like a high frequency when compared to most other waves, even sound waves, yet because radio waves travel so fast, the wavelength is slightly greater than 387 metres in wavelength, which is almost 424 yards in wavelength.

When comparing wavelength to frequency, one is the inverse of the other so this means that the higher the frequency, the shorter the wavelength, with the rate of travel (velocity) being the factor that determines what sort of figures we come up with when comparing one to the other.
