It is false that the amplitude of a wave is the distance between a point on one wave and the identical point on the next wave.
What is amplitude?The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position, as defined in physics. It is one-half of the length of the vibration path.
The energy of the disturbance that causes the wave determines the amplitude of the wave. The amplitude of a wave caused by a more energetic disturbance is greater.
A wave's amplitude is the distance from the center line to the top of a crest or the bottom of a trough.
The amplitude of a wave is the height of the wave measured from its highest point to its lowest point. The length of a wave from one peak to the next is referred to as its wavelength.
Thus, the given statement is false, as the definition is of wavelength and not of amplitude.

What is a mixture called when it has its different components mixed unevenly within the substance?
Heterogeneous mixture
Homogeneous mixture
Impure mixture
Pure mixture
Answer:
When 2 or more pure substances are mixed together they form a mixture. If the mixture has its different components mixed evenly within the substance it is a homogeneous mixture. Whereas if the mixture has its different components mixed unevenly within the substance it is a heterogeneous mixture
What is the natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America? Is it the Jet Stream, the Gulf Stream, La Niña, or El Niño? This is a science question about weather.
Answer:
El Niño
Explanation:
The natural reason for the rising surface temperatures of the Pacific Ocean, drought in the western United States, and flooding on the Pacific coast of South America Is the El Niño.
El Niño is a climate pattern that happens when there is an unusual warming of the surface temperatures of the Pacific Ocean. This occurs at an interval of two to seven years
During El Niño, the surface waters of the Pacific Ocean become warmer than average and this is as a result of the weakness of trade winds which blows over the entire Pacific Ocean. This makes the atmospheric pressure above the ocean to decrease.
El Niño brings rainfall nd flooding to South America and droughts in the western United States

1. Find the mass of 0.89 mol of CaCl2.
Answer:
97.9
Explanation:
m= n*M
M CaCl2= 40+ 35.5*2= 110
m= 0.89*110= 97.9
The mass of the given mole of [tex]CaCl_2[/tex] is required.
The mass of the given compound is 98.78 g.

Aluminum has metallic bonds between its atoms. Which statement BEST describes the
valence electrons in aluminum?
are exchanged with nonmetal atoms
are exchanged with other metal atoms
are localized and stay between metal atoms
are delocalized and move between metal atoms
Look at picture
ASAP please will mark as brainlist don’t got much time
Answer:
are delocalized and move between metal atoms
Explanation:
As the problem says, aluminum has metallic bonds. The main characteristic of metallic bonds is that the electrons are free to move between the metal ions (they are delocalized), thus being responsible for the good electrical conductivity of metals.

Write about similarities and the differences of the plant and animal cell
Answer:
Mark me as brainliest pls
Explanation:
similarities: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal element
differences: A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. ... Animal cells simply have a cell membrane, but no cell wall.
