A broad, flat area of land on both sides of a river, where sediments are deposited when it overflow its banks is called a floodplain.

A river can be defined as a large natural body of fresh water that flows continuously into an ocean, lake, sea or another river. Some examples of a river include the following:

A floodplain simply means a broad, flat area of land on both sides of a river, where sediments are deposited when it overflow its banks. Thus, a floodplain is an area of broad, flat land near a river that is usually flooded when the river overflow its banks or becomes too full.

In conclusion, old rivers are typically characterized by floodplains.

The acceleration of a 100 kg canoe with a force of 1000 N applied to it is 10 m/s²,

calculated using the formula a = F / m.

The acceleration of a 100 kg canoe that feels a force of 1000 N can be calculated using Newton's second law of motion, which states that acceleration is equal to the net force divided by the mass of the object. Hence, the acceleration a is given by the formula:

a = F / m

Where F is the force exerted on the canoe and m is the mass of the canoe. Substituting the given values:

a = 1000 N / 100 kg = 10 m/s²

Therefore, the acceleration of the canoe is 10 meters per second squared (m/s²).

Answer:

4/5

Explanation:

Answer: 16/20 reduces to 4/5 it is proportional

Answer:

D all of the above

Explanation:

Melting point represents the exact temperature at which the solid state changes to the liquid of a given substance. Water is one of the most commonly used elements to exemplify the melting point principle. For this solid state (ice) to take the form of liquid water, it must be exposed to a temperature of at least 0 °C. Thus, the melting point of water is equal to 0 °C.

The salt has a melting point of 801 ° C, the melting point of sugar is 185 ° C and the melting point of flour is 264 ° C. From this we can see that all these products have a higher melting point than water.

The answer to your question would be:: the wind because it carries the sand until it runs into an obstacle

Sand dunes: These are small hills made up of lose sand.

During formation of dunes ( in deserts or sea shores) there is creeping of sand particles along one side and there is sliding of sand on other side resulting in formation of a dune.

Thus the agent causes sand dunes to form is the wind carries the sand until it runs into an obstacle

Rose thorn is a eukaryotic plant cell. It is a type of eukaryotic cell.

Eukaryotic cell is defined as the cells with a well-organized nucleus and organelles surrounded by membrane-bound organelles.

The major difference between plant cell and animal cell is that one cell has lysosome present in it while other does not have lysosomes.

It can also be defined as the cell that contain the nucleus, mitochondria, and endoplasmic reticulum are all membrane-bound organelles.

There are various cell present in the eukaryotic cells sech as

The correct answer is eukaryotic plant.

A rose thorn is a part of a rose plant, and like all plant cells, it is classified as a eukaryotic cell. Eukaryotic cells are characterized by the presence of a true nucleus and other membrane-bound organelles. Additionally, plant cells contain chloroplasts, which are the sites of photosynthesis, and a rigid cell wall that provides structure and support to the plant. Since a rose thorn is part of the plant's defense mechanism and not an animal cell, the correct classification is eukaryotic plant cell. Chloroplastic is not a cell type but rather refers to the presence of chloroplasts within plant cells.

The following examples of failed experiments that produced valuable information

1) Bubble Wrap: The scientists were trying for  trendy new textured wallpaper, they failed miserably ,however the new wrap was a breakthrough in packing industry

2) Pacemaker: During development of a  heart rhythm recording device, Greatbach  pulled out the miss sized small resistor which sounded like a human heartbeat and thus leads to development of pacemaker

Explanation:

When a solution is acidic in nature then it means its pH range is from 1 to 6.9. And, in an acidic solution there are more number of hydrogen ([tex]H^{+}[/tex]) or hydronium ([tex]H_{3}O^{+}[/tex]) ions as compared to hydroxide ions ([tex]OH^{-}[/tex]).  

Some properties of acids are as follows.

Now, since the white solid substance isolated from lemon juice shows all the properties of being an acid.

Thus, we can conclude that the original white powder isolated from lemon juice is an acidic substance.

The white solid isolated from lemon juice is citric acid.

It has a sour taste, an acidic pH, and turns litmus paper red.

Here's how we can identify it:

Summary

Answer:

1. A. Tornado

2. A. High cumulonimbus

3. A. Air pressure differences over the ocean cause fast, spinning winds.

4. C. Both form when warm air rises, then cools quickly to form clouds.

5. B. False

6. A. Tornado

Explanation:

If it continues to grow, its upper part will be rounded and form like a small bald spot, called cumulonimbus calvus. Now they are associated with huge waterspouts, but without an electrical device. When lightning and thunder appear, we will have reached the mature phase of the storm and there is talk of cumulonimbus capillatus. Its upper part resembles a chapel or anvil, that is, the storm in its purest form.

The answer is:  C. It is a weighted average, so common isotopes have a greater effect than uncommon ones.

Isotopes are chemical elements with same atomic number, but different mass number (different number of neutrons).

Isotope of chlorine-35 has mass number 35. Mass number is sum of protons and neutrons, so number of neutrons in chlorine-35 is 18 (35-17).

Isotope of chlorine-37 has mass number 37. It has 20 neutrons (37-17).

Because the average atomic mass is closer to chlorine-35, there is more this isotope in nature.

Answer: C)  other cells.

Answer: Metal, OH-.

Explanation:

Bases are characterized by the formation of OH- which results when the bases are dissolved in water. Bases that produce many OH- ions in water solution are strong bases. Those that produce few OH- are weak bases. Since it produces hydrogen and hydroxide ions, water has characteristics of both acids and bases.

All bases contain at least one metal plus hydrogen and oxygen combined in a hydroxide ion.

Bases can be neutral molecules, anions, or cations that accept protons to form water. The hydroxide ion is a characteristic feature of common bases.

Bases fall into three categories: neutral molecules like H₂O, NH3; anions like OH¯, HS¯; and cations like [Al(H₂O)5OH]²†. Common bases include NaOH and Ca(OH)2 that contain the hydroxide ion OH¯. Bases accept protons from acids to form water through the reaction: H+ + OH¯ → H₂O.
