Microwaves have a higher frequency than radio waves, so why is it that they don't travel faster?
Answers
Answer: Energy requirement or consumption also increases as frequency goes higher. Hence, those low-frequency to mid-frequency waves are commonly referred to as radio waves and essentially, they have longer wavelengths. On the other hand, microwaves have higher frequencies and shorter wavelengths.
Explanation: therefore that's why they don't travel faster.
Microwaves have a higher frequency than radio waves, but don't travel faster as a result of low wavelength and energy.
What is Wavelength?
This is defined as the distance between corresponding points of two consecutive waves.
Radio waves have a higher wavelength and energy which is why they are able to travel faster and larger distances.

The image of the letter "d" under a microscope will depend on the type of microscope being used and the orientation of the letter on the stage. However, in general, if the letter "d" is placed on the stage of a compound microscope, the image will be inverted and reversed from left to right.

Explanation:
First we want to know what the word “ pigament “ means
A pigment is known substance that provides color to a material by selectively absorbing all and reflecting certain wavelengths of light something like how a rainbow works through the prism. In the context of color, pigments are often used in paints, inks, dyes, and other coloring materials to produce a desired hue.
They are mainly composed of small, insoluble particles that are suspended in a medium and which can be applied to surfaces or incorporated into materials to produce color. Pigments can be made from a wide range of natural and synthetic materials, and their properties, such as color, lightfastness, and durability, can vary widely depending on the type of pigment and the method of application.
How are they made:
Synthetic organic pigments are derived from coal tars and other petrochemicals or basically they just come from coal and other petrochemicals.
Thus the answer to your problem is, above

List three evidences that show that the Bible is the Word of God.
Answers
Answer:1.God tells us that He is the Author (2 Peter 1:20-21 Open in Logos Bible Software (if available) & 2 Timothy 3:15-17 Open in Logos Bible Software (if available))
1.The Old Testament and New Testament Authors understood they were writing the Word of God. Common Old Testament phrase – “Thus saith the Lord”. The Apostle Peter confirmed the Apostle Paul’s writings as Scripture (2 Peter 3:16)
3.Its Historical Accuracy – as verified by archeology, which has never contradicted the Bible, but only confirms and silences its critics.
Explanation:
Answer:
Many people question who the author of the Bible is and wonder if the Bible is really the Word of God. I want to give you five reasons to affirm that the Bible is God's Word.
The Word of God: Evidence that Scripture is Divine
First, I believe the Bible is the Word of God because of its scientific accuracy. The Truth of the Word of God tells us that God “hangeth the earth upon nothing” (Job 26:7). How did Job know that the earth hung in space before the age of modern astronomy and space travel? The Holy Spirit told him. The scientists of Isaiah’s day didn’t know the topography of the earth, but Isaiah said, “It is [God] that sitteth upon the circle of the earth” (Isaiah 40:22). The word for “circle” here means a globe or sphere. How did Isaiah know that God says upon the circle of the earth? By divine inspiration.
Secondly, the Bible is affirmed through historical accuracy. Do you remember the story about the handwriting on the wall that is found in the fifth chapter of Daniel? Belshazzar hosted a feast with a thousand of his lords and ladies. Suddenly, a gruesome hand appeared out of nowhere and began to write on a wall. The king was disturbed and asked for someone to interpret the writing. Daniel was found and gave the interpretation. After the interpretation, “Then commanded Belshazzar, and they clothed Daniel with scarlet, and put a chain of gold about his neck, and made a proclamation concerning him, that he should be the third ruler in the kingdom.” (Daniel 5:29). Basing their opinion on Babylonian records, the historians claim this never happened. According to the records, the last king of Babylon was not Belshazzar, but a man named Nabonidas. And so, they said, the Bible is in error. There wasn’t a record of a king named Belshazzar. Well, the spades of archeologists continued to do their work. In 1853, an inscription was found on a cornerstone of a temple built by Nabonidas, to the god Ur, which read: “May I, Nabonidas, king of Babylon, not sin against thee. And may reverence for thee dwell in the heart of Belshazzar, my first-born favorite son.” From other inscriptions, it was learned that Belshazzar and Nabonidas were co-regents. Nabonidas traveled while Belshazzar stayed home to run the kingdom. Now that we know that Belshazzar and Nabonidas were co-regents, it makes sense that Belshazzar would say that Daniel would be the third ruler. What a marvelous nugget of truth tucked away in the Word of God!

the pressure in Arabian sea is much bigger than near the surface?

Answers
Answer:
In general, the annual sea surface temperatures(SSTs) in the Bay of Bengal(BOB) are higher than the Arabian sea(AS). because, there are two main reasons for higher SST in the Bay of Bengal than the Arabian Sea. they are 1. stratification, 2.strong mixing
stratification is nothing but a phenomenon which stratifies(layers) the sea water when different density water(fresh water, rain water) add into the sea water. So the stratification in the bay of Bengal is comparatively high than the Arabian sea due to the high river discharge and precipitation in the BOB than the AS. the mixing process over the Arabian sea is higher than the Bay of Bengal due to the prevailing of strong winds over the AS (because of the presence of the mountains of east Africa) than Bay of Bengal (because of the winds over the BOB are sluggish in nature then the AS). But generally winds over the sea mixes easily the normal sea water than stratified/stabilized sea water column. That's why less mixing will takes place over the surface of BOB than the AS. So due to the presence of less mixing over the surface of the Bay of Bengal than the Arabian sea, the SST values over the Arabian sea are always lower than the Bay of Bengal. that's why the Arabian sea is colder than the Bay of Bengal.

How do we know there has not been an increase in the number of earthquakes? Officials from the U.S. Geological Survey, the government agency that keeps track of earthquakes, point to statistics. On average, there have been no more earthquakes so far in 2010 than there were in previous years.
What Happens During Earthquakes?
In reality, it's not the number of quakes that has gained our attention, but the devastating impact quakes can have. Earthquakes are very natural—it's inevitable that they'll happen because of the way the planet works. The earth's surface is made up of tectonic plates that fit together like puzzle pieces and are always moving past each other. When two of the plates' edges get caught, stress builds up at the fault line—the crack between the plates. When the plates are finally able to break free of each other, the stress is released, and an earthquake occurs. Earthquakes of varying strengths happen every day, usually at fault lines. Some of these quakes have a high magnitude, while others are relatively weak. But it's often where an earthquake takes place that determines whether it will be something that goes largely unnoticed, or a disaster that affects thousands of people.
What Is Changing?
In the past, earthquakes were not as much of a problem because Earth's population was smaller, and cities were less populated.
"Look at some of the big [earthquakes] recently," said Debarati Guha-Sapir of the World Health Organization. Guha-Sapir cited some earthquakes that took place in areas where the population had increased in recent years, making the quakes more serious. "Had the Izmit or Bhuj quakes [of 1999 and 2001] happened 30 years ago, the events would have been relatively insignificant, as the [populations] of these cities were a third of what [they were when the earthquakes happened]. Increasing population density makes a small event into a big one."
Some of the earthquakes that took place in early 2010 occurred in highly populated areas, as well. More people are moving into megacities that happen to be built on fault lines—and many cities are on fault lines. Of the 130 cities with more than one million people, more than half are in earthquake zones, making them more prone to earthquakes.
In many of these cities, officials have drawn up laws requiring that buildings be designed and constructed to endure earthquakes. But some cities, particularly those in developing countries, lack the resources to do this. There, people are rapidly putting up substandard buildings that can't withstand the force of the shaking earth. For example, the Haiti earthquake took place near the nation's crowded capital. There was a great deal of destruction because there were "too many people crammed into a city that wasn't meant to have that many people and have an earthquake," said University of Miami geologist Tim Dixon.
Another reason quakes seem worse is that we're paying more attention. Everyone noticed when the Haiti earthquake was quickly followed by the Chile earthquake. Many people watched the news and the Internet for updates on these disasters, unable to believe that they were seeing two major earthquakes in such a short period of time. But eventually, the earth will have a period when earthquakes are minor or in unpopulated areas. Then people won't notice quite so much anymore.
"People are paying attention to the violent planet we've always lived in," said Dennis Mileti, a seismic researcher. "Come back [at a time when] there have been no [noticeable] earthquakes, [and] most people will have forgotten [about them] again."
According to the article, what is one reason why it seems as if the world is experiencing more earthquakes than usual?
Answers
Answer: because there has not been one in years
