Ultrasonic waves can be categorized into two types: longitudinal waves, which cause the particles of the medium to move parallel to the direction of the wave's propagation, and transverse waves, which cause particles to move perpendicular to the wave's direction. When it comes to flow measuremen...
By what factor must the amplitude of a sound wave be decreased in order to decrease the intensity by a factor of 4? If the intensity is 300 and the amplitude is 200. When the amplitude is increased to 800 what will be intensity?
positions on general mandated face mask use were highly divergent across countries and subject to change within countries [1,2]. Several countries discouraged the use of face masks due to a lack of evidence of its effectiveness, to preserve...
We test whether the co-residence of older parents with their adult children of reproductive age increases the chance of them forming a multichild family. Using data from Wave X of the Luxembourg Wealth Study (LWS) and multinomial logistic regression, we model the number of children using the bi...
Then, you are going to draw a diagram showing how sound waves move. Does anyone have any questions? Allow about 10 minutes for the students to write a summary about sound. Feedback: Say: Who would like to share your diagram of sound waves and what you wrote? (Allow the students to an...

that we have a better understanding of the ship model. Therefore, it is very important for us to take a good look at the drawings and find out the technical requirements, which is the preparation of materials and tools, the methods and steps of making decisions. In order to represent a ...
To start with, studies draw on differentclassification systemsto identify STEM majors and occupations. Very few empirical studies on the leaky STEM pipeline use international classifications, such as the ISCED-F 2013 to code fields of study or the ISCO-08 coding for occupations (exceptions are; Ba...
Our distinction in low (no regulations), medium and high stringency allows us to draw the conclusion that in a situation without any regulations trust and perceived clarity of communication negatively associate with mask use. In countries without face mask regulations or recommendations, governments ...
