To solve the question, "Longitudinal waves cannot," we need to analyze the properties of longitudinal waves and determine which of the provided options is incorrect.1. Understand Longitudinal Waves: - Longitudinal waves are
The correct Answer is:B To solve the question regarding the propagation of a longitudinal wave through a material medium, we will analyze the quantities transmitted in the direction of propagation step by step. Step 1: Understanding Longitudinal WavesLongitudinal waves are characterized by the oscillat...
Longitudinal waves are the mechanical waves in which the vibration of the particles takes place in the same direction as that of the wave. Sound waves, seismic waves are the examples of longitudinal waves.
Methods: We included 12,331 participants (aged ≥ 80 years) (mean [SD] age: 89.5 [7.0] years) who managed to perform ADL independently at baseline in the Chinese Longitudinal Healthy Longevity Survey 1998-2014 waves. Cox proportional hazards models were used to examine whether leisure activities...
Second, future studies could benefit from a research design with three or more waves. On the one hand, such a design would yield more precise information on the relations among the studied variables (MacKinnon, 2012). On the other hand, having more than two waves would allow the lags of ...
(1 = correct answer; 0 = incorrect answers) to calculate their nutritional knowledge and summed up the three dummies resulting in a summated index ranging from 0 to 3. While the questions themselves stayed unchanged between the two waves, the pictorial food options were updated to prevent possib...
Drop-out analysis has shown that participants responding to all survey waves are slightly older, include more males, and have a higher education than the average working population in Finland according to the official statistics of Finland [40]. Analytical weights were used to correct biases of ...
In this paper, we have described the SERL Observatory dataset and detailed the key processes involved from participant sample selection, recruitment, data collection, analysis, provisioning and researcher access. Our three recruitment waves during 2019–2021 and stratified random sampling approach ultimate...
