Scaffolding Incident Example The Scaffolding on the swing-stage of Metron Construction had only two lifelines available for seven men and only one was using the fall protection. Five men fell to the ground when the stage broke, four does instantly and the other left permanently disabled. Physical hazard Typically entails a transfer of energy that results in injury T/F: Noise and vibration are considered physical hazards True What is the most common physical injury? Conta...

COMD 5070 - Exam 2 What is fundamental frequency? - fundamental frequency is a physical measure - it is the speed of vocal fold vibration - correlates to the perceptual correlate of pitch - lowest frequency of a periodic waveform Can complex waves still be periodic? Yes, complex waves can still be periodic. Periodic means that a wave has a repeating pattern. Complex means that there is more than one frequency present. These two things can exist. The wave will have a unique pattern wit...

A client is in the recovery phase of intervention after having had an acute onset of Guillain Barre Syndrome one month ago. The OTR advises the client that using assistive devices will improve independence, but the client refuses to use the devices stating: "My wife is happy to help me whenever I need it." How should the OTR respond to the client's comment? A. Convince the client to try at least one device B. Discuss the comment with family members C. Use other techniques to maximize indep...

The 2 types of powered instrument devices are ____________ and ____________. correct answer: sonic, ultrasonic The 2 subtypes of ultrasonic powered devices are ______________ and _______________. correct answer: piezo, magneto What are some benefits/strengths of the powered instruments over hand instruments? correct answer: -several mechanisms of action (mechanical calculus removal, water irrigation, and cavitation) -small size of instrument working-end -easily inserted in pocket wit...

loudness Correct Answer-how we perceive intensity/amplitude; measured in decibels (dB); determined by how much pressure our lungs put on vocal folds pitch Correct Answer-how we perceive rate of vocal fold vibration (frequency); measured in hertz; number of complete vibrations; conveys meaning rachel kolb Correct Answer-had a cochlear implant in one ear and hearing aid and other has hearing aid; masters degree in english; deaf but still able to talk deaf Correct Answer-hearing loss great...

A vibration is also known as a ___ in time ANSWER: wiggle A wiggle in both time and space is known as a ___ ANSWER: wave If the mass of the object hanging on the end of a string of a pendulum is doubled, how is the period of the pendulum affected? ANSWER: Nothing is affected by mass. If the amplitude of a wave is 2 meters, then the trough to crest distance of the wave is ANSWER: 4. If the frequency of a certain wave is 20Hz, then its period is ANSWER: 1/20 s Deeagles - Stuvia US...

Merkell cells - ~~> - slowly adapting - 25% of mechanosensory afferents in hand - highest spatial resolution - edges, points, corners, curvature - static indentation ** Meissener - ~~> - rapidly adapting -40% of mechanosensory innervation in hand - skin motion, indentation, low frequency vibrations for textured objects*** - more than 4x more sensitive than Merkell to skin deformation, but larger receptive fields so less spatial resolution - ie. tea set plate etchin...

Which term is used to refer to a wave's rate of vibration? Ans- B. frequency On the figure, which letter represents a refracted ray of light? Ans- C (BUT D on test) On the electromagnetic spectrum, which type of wave has the shortest wavelength? Ans- A. cosmic ray Dyes are often used during microscopy to increase which of the following? Ans- A. contrast Which of the following was the first to use the term "cells"? Ans- A. Robert Hooke Which of the following is the typical magnific...

Source filter model (4) - ANSWER-~ the larynx serves as the sound source and its output is then sent into the vocal tract which filters it. ~ larynx on its on cant produce any sound unless there is pressure driving it ~ pressure comes from the lungs ~ vocal tract doesn't just filter but resonates or enhances some sounds Pitch (2) - ANSWER-Stretch the vocal folds to increase their tension and therefore increase the frequency at which they will vibrate ~ Contracting the cricothyroid muscle...
