Water evaporating in an open system, water freezing, cookie dough baked into a cookie, and sugar dissolving into water are all examples of statements that demonstrate the law of conservation of matter.

What is law of conservation?A conservation law in physics asserts that a specific observable property of an isolated physical system doesn't change over time.A physical property, or measurable amount, does not change over time in an isolated physical system, according to the conservation law, often known as the law of conservation, which is a principle in physics.According to the principle of mass conservation, neither chemical processes nor physical changes can create or destroy mass in an isolated system. The mass of the products and reactants of a chemical reaction must be equal, in accordance with the law of conservation of mass.

The electromagnetic spectrum is the portion of energy that reaches the Earth from the Sun. However, the human eye can still only detect a portion of that spectrum because of the _____________ of the visible light waves.

amplitude

wavelengths

crests

troughs

Answers

Answer: I’m stuck between amplitude and wavelengths but I do think it’s wavelengths.

Correct me if I’m wrong! ^^

The human eye can only detect a portion of that spectrum because of the wavelength of the visible light waves. Therefore, option (B) is correct.

What are frequency and wavelength?

The wavelength of the light can be defined as the distance between the two adjacent points of a wave w.r.t. each other. Two crests on a wave are separated by a distance known as wavelength.

The frequency of the wave can be defined as the number of oscillations of a wave in 1 sec. The frequency has S.I. units per second or hertz.

The relationship between wavelength, frequency (ν), and speed of light (c) is as follows:

c = νλ

The part of the electromagnetic spectrum that is visible to the human eye is known as the visible spectrum. The electromagnetic radiation of the visible spectrum is known as visible light.

Human eyes can detect the wavelength of range from 380nm to 740nm. This wavelength range of visible light corresponds to a band of frequency between 405 THz to 790 THz.

(HELP I DONT KNOW HOW TO DESCRIBE IT BUT I SEE THE SIMILARITIES) Look at the green lines you created by connecting the three boiling point data points and the three melting point data points. For each of these lines, describe any trends you see.

Answers

Answer: There will be an increase in the boiling point with an increase in the molecular mass.

Explanation:

The melting point is the temperature at which the substance changes from a liquid state to a vapor state at a constant pressure. The pressure required to effect this change is known as the vapor pressure. The higher the vapor pressure, the higher the boiling point and the lesser time it takes for the substance to escape from the liquid state. In this case, a higher molecular mass means more energy is needed to make sure that there is a gaseous change. In addition, the higher melting point requires the lower temperature as well.

Thanks! :) PLEASE PROOFREAD WILL MARK BRAINLIEST!The benefits of starting school laterNo one likes having to wake up early for school and as kids grow into their teenage years, they are forced to wake up even earlier as they move on from elementary school to middle school and high school. When students get older, it gets even harder to wake up and it leads to many obstacles that can be avoided by starting school at later times. By starting schools later, students have been shown to improve academically, be more productive, not skip school, and maintain better health. A later start time should be incorporated into schools everywhere, especially high schools, for the benefit of teenage students.Grades are a very important aspect of education to many high school students, and grades are immensely dependent on adequate sleep. Later start times would allow for a greater quantity and quality of sleep. Poor sleep has a negative effect on a students academic performance. According to the Centers for Disease Control and Prevention (CDC), Adolescents who do not get enough sleep are more likely to perform poorly in school. Students who are not afforded the opportunity to get in the sufficient sleep they need will have a harder time focusing in school and doing well on exams. If schools were to push back the starting times in order to allow students to have a finer capacity of sleep, then the academic performance would improve, thus contributing to the common interest of all students.Many teenagers fall victim to car accidents and poor attendance records. Later start times would mean an improvement in attendance and safety as fewer students would sleep in or fall under the risk of driving to school in drowsy conditions. Enabling students to sleep more would cause more students to come to school on time and make them less likely to drive to school in a fatigued state. The Science Daily revealed that [...] later school start times were associated with a significant drop in vehicle accidents involving teen drivers. This could be tied to the fact that teens are in a more rushed mood to get to school on time from waking up late or that they are driving while tired, which can lead to many dangers. By starting schools at later times, the risks of teen car accidents would be reduced and the overall attendance would improve, thereby allowing for the betterment of students in all placesEven with all the benefits of starting school at later times, there still remain those who challenge the idea. A common counterargument from the individuals in opposition to pushing back the schools starting times is that students should just sleep earlier. However, research has demonstrated that teenagers are biologically more likely to fall into a deeper sleep at later times. Science advocates say that young people's body clocks may shift as they reach their teenage years - meaning they want to get up later not because they are lazy but because they are biologically programmed to do. The biological clock of a teen does not correspond well with the schools starting times, and when a student is forced to wake up too early they are neglecting crucial parts of their sleep. In order to align better with teenagers internal clocks, schools should start at later times, which in return would result in the improvement of learning, concentration, and health.Students commit a large portion of their day towards school and it would be a more enjoyable process if schools were to start at a more seemly time. For the general welfare of students in public education, the school start times should be moved to later times. The benefits include better grades, fewer absences, safer roads, and increased attentiveness. There is additional potential to starting schools later, such as the reduction of risk in athletics, less depressive symptoms, and a decrease in the likelihood of participating in violence. The further possibilities can only be explored as more schools start pushing back their start times and in the idealistic future, schools will hopefully start to implement a delay to start times as it is better for everyone.
