Answer:
Like any wave, a sound wave doesn't just stop when it reaches the end of the medium or when it encounters an obstacle in its path. Rather, a sound wave will undergo certain behaviors when it encounters the end of the medium or an obstacle. Possible behaviors include reflection off the obstacle, diffraction around the obstacle, and transmission (accompanied by refraction) into the obstacle or new medium
Answer:When sound waves move from one medium to another, there will be changes to the velocity (or speed), frequency and wavelength of the sound wave. This change in velocity can also result in a change of direction of the sound wave - also known as refraction

Are there any steps of the rock cycle that do NOT connect directly to one another? Explain why this may be the case using at least two examples.
please helpp
Answer:
rocks are destroyed
explanation
ricks are never destroyed they descompose
There are no steps in the rock cycle that do not connect directly to one another. The rock cycle describes the continuous process by which rocks are formed, weathered, eroded, transported, deposited, and lithified, leading to the formation of new rocks.
What are the steps in rock cycle ?Each step of the rock cycle is interconnected and depends on the other steps. For example, the formation of sedimentary rocks requires the weathering and erosion of preexisting rocks, the transportation and deposition of the resulting sediments, and the lithification of the sediments into rock.
Without the weathering and erosion of preexisting rocks, there would be no sediment to form sedimentary rocks.
Similarly, the formation of metamorphic rocks requires the heat and pressure of burial and tectonic activity, which in turn is influenced by the existing rock formations and geological processes of the area.
Another example is the formation of igneous rocks, which can occur through the melting and solidification of preexisting rocks, or through volcanic activity.

sound waves.
Hard materials such as brick walls tend to block sound waves while soft materials such as a thick carpet tend to absorb sound waves.
What are sound waves?A sound wave is defined as the pattern of disturbance which is caused by the movement of energy traveling through a medium as it propagates away from the source of the sound.
Sound waves are created by object's vibrations and produce pressure waves, for example, a ringing cellphone. The pressure wave disturbs the particles present in the surrounding medium, and those particles disturb others present next to them, and so on.
The pattern of the disturbance creates outward movement in a wave pattern, like sea water in the ocean. The wave carries the sound energy through the medium, usually in all directions and less intensely as it moves farther from the source.

Answer: The Shape of Molecules
The three dimensional shape or configuration of a molecule is an important characteristic. This shape is dependent on the preferred spatial orientation of covalent bonds to atoms having two or more bonding partners. Three dimensional configurations are best viewed with the aid of models. In order to represent such configurations on a two-dimensional surface (paper, blackboard or screen), we often use perspective drawings in which the direction of a bond is specified by the line connecting the bonded atoms. In most cases the focus of configuration is a carbon atom so the lines specifying bond directions will originate there. As defined in the diagram on the right, a simple straight line represents a bond lying approximately in the surface plane. The two bonds to substituents A in the structure on the left are of this kind. A wedge shaped bond is directed in front of this plane (thick end toward the viewer), as shown by the bond to substituent B; and a hatched bond is directed in back of the plane (away from the viewer), as shown by the bond to substituent D. Some texts and other sources may use a dashed bond in the same manner as we have defined the hatched bond, but this can be confusing because the dashed bond is often used to represent a partial bond (i.e. a covalent bond that is partially formed or partially broken). The following examples make use of this notation, and also illustrate the importance of including non-bonding valence shell electron pairs (colored blue) when viewing such configurations .
Methane Ammonia Water
Bonding configurations are readily predicted by valence-shell electron-pair repulsion theory, commonly referred to as VSEPR in most introductory chemistry texts. This simple model is based on the fact that electrons repel each other, and that it is reasonable to expect that the bonds and non-bonding valence electron pairs associated with a given atom will prefer to be as far apart as possible. The bonding configurations of carbon are easy to remember, since there are only three categories.
