do you think the reflected waves would ever return to the airplane that transmitted them? explain
The reflected waves should not return back to the transmitted source if there no hindrances in the moving trajectories. If there is any hindrance or objections in front of the reflected wave there may occur some directional change and does not return to the airplane.
What is reflection?Reflection is phenomenon by which an incident wave on an object return backs in the straight direction. Reflection make an object shiny as we see from a mirror.
When light passes through a transparent or translucent material it penetrates through it and will refract or scatter from the object. This will happen when the frequency of the incident light does not matches with the frequency of the incident light.
If the a some waves are transmitted from an airplane and they are reflected in a straight direction, it will not revert back to the airplane because the reflected light will moves in a straight direction back from airplane.

What is convection?
a Transfer of heat through objects touching the source
b Transfer of heat through direct physical contact
c Transfer of heat through electromagnetic waves
d Transfer of heat through the movement of particles
Answer:
d transfer of heat through the movement of particles
The correct answer is option d: Transfer of heat through the movement of particles. Convection is a mode of heat transfer that occurs through the movement of particles.
Convection is the transfer of heat through the movement of particles in a fluid, such as a gas or liquid. Option (d) is the correct answer. Convection occurs when a temperature difference exists within the fluid, causing the hotter particles to become less dense and rise while the cooler particles sink. This movement creates a circulation pattern known as convection currents. Convection is a significant mechanism for heat transfer in various natural and man-made systems. For example, when a pot of water is heated on a stove, the bottom of the pot gets hot, causing the water near the bottom to heat up and expand. This hot water rises to the top, transferring heat to the surrounding cooler water. As a result, the water circulates in a convection current, leading to a more uniform distribution of heat. Convection is also responsible for phenomena like ocean currents, atmospheric circulation, and even the formation of thunderstorms. It plays a crucial role in distributing heat within the Earth's atmosphere and oceans, impacting weather patterns and climate.

The negative electrons are in motion around the positive nucleus to which they are attracted is true related to atom. Thus option a is correct.
What are atoms?Atoms are defined as the smallest unit into which matter can be divided without the release of electrically charged particle.
It is also defined as a building block of all the matter, created after big bang theory.
Electrons are defined as a negatively charged subatomic particles that together with protons and neutrons form an atoms nucleus.
Nucleus are defined as the central region of an atom where the majority of masses are concentrated and contains protons and neutrons.
Thus, the negative electrons are in motion around the positive nucleus to which they are attracted is true related to atom. Thus option a is correct.

Answer:The Law of Conservation of Mass simply states that the total amount of mass should not change in a chemical reaction that is isolated (no other objects can enter the reaction). The total mass of the reactants must be equal to the total mass of the products. Thus, the correct estimate of the amount of oxygen used in the interaction is the difference between 133 g and 29 g.

Answer:
A benefit of the opinion of a scientific author is that you can see others points of view on a subject. A drawback is that they are using an opinion and most likely not stating unbiased facts.

Answer:
Highlights:
*Researchers in the sciences do not see access to the scientific literature as an especially important problem.
*Authors consider factors such as journal reputation and the absence of publication fees when deciding where to submit their work. In contrast, free access is not a significant factor in their submission decisions.
Implications:
*While open access has the potential to expand the authorship and readership of the scientific literature, that potential has not yet been realized.
*Librarians who encourage scientists to publish in open access journals should be aware of the authors' priorities and perspectives. Authors in the sciences tend to focus on citation impact, reputation, and accessibility to a specialized readership—not breadth of readership, copyright, or access status.
*Journal publishers that charge publication fees may want to consider alternative sources of revenue. Authors' resistance to publication fees is a major barrier to greater participation in open access initiatives.

1. Describe how the motion of a spring being pushed forward and backward is similar to the motion of air particles in a sound wave.
The motion of spring is similar to that of sound wave in that the direction of the particles of the medium is parallel to the direction of the wave.
Motion of springThe motion of a spring pushed forward and backward under goes simple harmonic motion that forms a sinusoidal path. In this type of motion, the direction of the particles of the medium is parallel to the motion of the wave.
Sound waveSound wave is mechanical wave in which the direction of the particles of the medium is parallel (longitudinal) to the motion of the sound wave.
Thus, motion of spring is similar to that of sound wave in that the direction of the particles of the medium is parallel to the direction of the wave.

Describe one piece of evidence that the wave carries energy from one place to another.
Answer:
Without shifting matter the entire distance, waves can transfer energy over distance. For instance, without the water itself moving many kilometers, an ocean wave may move many kilometers. The stream, a motion known as a disruption, goes up and down. It is the disruption that flows in a wave, transferring power.

Compare and contrast surface waves with transverse waves and with longitudinal waves.
Answer:
Explanation:
In longitudinal and transverse waves, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction (respectively) relative to the direction of energy transport. In a surface wave, it is only the particles at the surface of the medium that undergo the circular motion.
Surface waves are a combination of transverse and longitudinal waves that move along the surface of a medium, while transverse waves involve vibrations perpendicular to the direction of wave propagation, and longitudinal waves involve vibrations parallel to the direction of wave propagation.
What are surface, transverse and longitudinal waves?Surface waves are a type of wave that travels along the surface of a medium. They are characterized by having both a transverse and longitudinal component, meaning that the particles in the medium oscillate both horizontally and vertically as the wave travels. Examples of surface waves include ocean waves, seismic waves, and electromagnetic waves.
Transverse waves are a type of wave that involves vibrations perpendicular to the direction of wave propagation. In a transverse wave, the particles in the medium oscillate in a direction that is perpendicular to the direction the wave is moving. Examples of transverse waves include electromagnetic waves such as light and radio waves, and mechanical waves such as ripples on the surface of water.
Longitudinal waves are a type of wave that involves vibrations parallel to the direction of wave propagation. In a longitudinal wave, the particles in the medium oscillate in a direction that is parallel to the direction the wave is moving. Examples of longitudinal waves include sound waves, seismic waves, and longitudinal electromagnetic waves.
