Answer:
corrosion of aluminum metal by hydrochloric acid - chemical change
melting wax - physical change
pulverizing an aspirin tablet - physical change
digesting a Three Musketeersbar - chemical change
explosion of nitroglycerin - chemical change
a burning match - chemical change
metal warming up, due to the burning match - physical change
water vapor condensing on the metal - physical change
the metal oxidizes, becoming dull and brittle - chemical change
salt being dissolved by water - physical change
Explanation:
A chemical change is one in which a new substance is produced and it is not easily reversible. A chemical change always goes with absorption or evolution of heat.
On the other hand, a physical change is one in which no new substance is formed and it is easily reversible.
The processes mentioned in the question were classified into physical and chemical changes as we can see in the answer section.

Dr. Alimam is studying infants’ ability to distinguish shapes. He shows an infant a shape until the
infant loses interest in the shape, and then he shows the infant a different shape. If the infant shows
interest in the new shape, he determines that the infant recognizes that the new shape is different from
the old one. Dr. Alimam expects that getting older will cause the babies to recognize shapes faster. He
records how long it takes the infant to show interest in the new shape.
Dr. Alimam conducts the study using a group of 5 three-month infants, 5 six-month infants, and 5 eight
month infants recruited from local day-care centers. Because he knows the directors, he does not
contact the infants' parents to inform them of the study. Below is a chart that shows the time it took for

Answer:
Both are professional titles acquired through specific schooling and a licensing process.
With regards to the building industry, an architect is the generalist and an engineer is the specialist. Generally, the architect is the conceptual designer of the project, involved through all stages of a project. Engineers come and go (some stay significantly longer than others) and focus on a specific aspect of a building such as the mechanical systems or the structure. Architects and engineers together make up "the design team," and they work together to make the design complete. Architectural elements may be moved for the structure to make more sense and vice versa. The architect is usually the overseer, communicating with all the disciplines involved. The architect is likely the first to notice that the proposed ductwork conflicts with a structural beam, for example.
If the project is large enough, you might have two sets of architect teams: the design architect and the executive architect, also known as the Architect of Record. The executive architect has a more technical focus.
The technical aspects of architecture include compliance with building codes and figuring out all the building stuff related to the final product. For example, a plumbing engineer's drawing will have a line on a drawing representing a plumbing line. An architect's drawing might include a detail that shows that plumbing line as an actual pipe with a thickness with the bricks and cement block of the wall it is penetrating as well as whatever seal will be keeping the rain out.
Because of the difference in role and scope between an architect and engineer, the engineer of a project will be working on many other projects simultaneously, while the architect is dedicated to a few or just the one.

Select two targets. Write two paragraphs, one for each target, identifying potential challenges that each target presents and describe possible methods to overcome those challenges. Use evidence from course content to support your responses.
Answer:
Explanation:
Target 1.1
By 2030, eradicate extreme poverty for all people everywhere is an extremely challenging target. First of all, there are almost 8 billions people on Earth. Each person in extreme poverty has different background and circumstances. It is difficult to come up with a plan that will help them all. The first step is international cooperation; involving rich countries giving ads to poorer countries.
Target 1.2
By 2030, reduce by half population living in poverty by national definitions is easier to accomplish than Target 1.1. The key here is "by national definitions." As different countries have different definitions for poverty, the standards are lower for poorer countries. Leaders in those countries will try to improve lives of their people so that they can be remembered as the ones who lift their countries out of poverty.

Get more crowded never loud
what is it ?
A superposition principle is something that allows a sound to be more crowded with sound waves, but not louder.
We can arrive at this answer because:
The superposition principle refers to the joining of many sound waves being emitted at the same time and coming together to form the sound.These waves do not affect each other, but add up, creating a deeper, more intense sound.As an example, we can use a stadium full of fans, the more crowded the more intense the fans' screams will be, but not louder, as the same waves will be emitted.
