What does wave speed have to do with all SONAR AND RADAR technologies?
What does the medium have to do with SONAR vs RADAR?
Answers
Explanation:
1) Radar uses radio waves, which are a type of electromagnetic energy. Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects. Sound waves are a type of acoustic energy. Because of the different type of energy used in radar and sonar, each has its own applications.
2)Radar systems operate using radio waves primarily in air, while sonar systems operate using sound waves primarily in water (Minkoff, 1991). Despite the difference in medium, similarities in the principles of radar and sonar can frequently result in technological convergence.

List an example of matter in each of the three states.
Answers
The example of matter in the three states is brick in solid state, water in liquid state and oxygen gas in gaseous state.
1. Solid: A brick is a solid object that maintains a fixed shape and volume.
2. Liquid: A glass of water is a liquid that conforms to the shape of its container but maintains a definite volume.
3. Gas: Oxygen gas in the atmosphere is a gas that does not have a fixed shape or volume, filling the available space.
The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, such as an ice cube. Liquids have a definite volume but take the shape of their container, like water. Gases have neither a fixed shape nor volume and fill the entire space available to them, such as the air we breathe.
In summary, the states of matter describe the physical properties of substances based on the arrangement and movement of their particles, with solids having a fixed shape, liquids taking the shape of their container, and gases being free-flowing and filling all available space.

Answers
Answer:
Explanation: COMPOST BIN
WHAT IS A COMPOST BIN?
A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.
Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost
Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.
The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.
CHOOSING THE RIGHT BIN
Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:
Plastic storage container
Plastic bucket
Trash cans
Straw bales
Lumber
Branches harvested from the woods
Stone
Cinder blocks
Wire fencing
Ceramic (also popular for a kitchen countertop compost bin)
The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.

Explain how kinetic energy and potential energy change as a rollercoaster moves up and down hills on its track.
Answers
Explanation:
Before the roller coaster starts moving, it is at rest and energy at rest is potential energy. As the roller coaster moves the potential energy is converted to kinetic energy as kinetic energy is energy in motion. As it gets to the top of a hill it assumes a rest position from a height for a short time and as it comes down the potential energy is converted again to kinetic energy. This continues for the whole ride until it comes to an end.

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!

Answers
Answer:
The maximum depth of the water at the place is 6.0 meters.
Given the tidal range and average depth, it is to be noted that the maximum depth of the water at the place, is 6.0 meters.
How can you calculate Maximum Depth using Average Depth and Tidal Range?The tidal range is the successive difference between tide highs and lows, which is a sinusoidal pattern. On the basis of the above, it is correct to state that the tidal range is twice of the amplitude of the tide level.
That is:
The Amplitude of the tide, A = 2.0/2m = 1m
The maximum depth at the place, therefore, is given as:
D\(_{max}\) = A + D\(_{ave}\)
Hence,
D\(_{max}\) = 1.0 + 5.0 = 6.0
Thus, it is correct to state that the Maximum Depth (D\(_{max}\)) = 6.0 Meters.

Use the data in the table to explain how you could determine the volume of the block.
Answers
To find the volume of the block, subtract the initial water volume from the final water volume, convert the change in water volume to cubic centimeters, and consider it as the volume of the block.
To find the volume of the block using the measurements provided.
1. Calculate the change in water volume:
The initial water volume is given as 62.3 mL, and the final water volume is given as 89.5 mL. To determine the change in water volume, we subtract the initial volume from the final volume: 89.5 mL - 62.3 mL = 27.2 mL. This value represents the increase in water volume caused by placing the block in the graduated cylinder.
2. Convert the change in water volume to cubic centimeters:
Since 1 mL is equivalent to 1 cubic centimeter (cc), we can directly convert the change in water volume from milliliters to cubic centimeters. In this case, the change in water volume is 27.2 mL, which is also equal to 27.2 cc.
3. Determine the volume of the block:
When the block is placed in the graduated cylinder, it displaces some amount of water, resulting in an increase in water volume. By measuring this increase in volume, we can determine the volume of the block itself. In this case, the change in water volume of 27.2 cc represents the volume of the block.
By following these steps, we can find the volume of the block based on the provided measurements.
Therefore, By deducting the initial water volume from the final water volume and converting the difference in water volume to cubic centimeters, the block's volume can be calculated. the volume of the block is 27.2 cc.
