which of the following statements describes noise?

Atmospheric noises 2. Noise power is also proportional to the bandwidth over which it is measured. B. The analysis of thermal noise is based on the Kinetic theory. d. It is a sound sustained continuously during both inspiration and expiration. I talked more quickly — more vehemently; but the noise steadily increased.” (Paragraph 17) Asked by Reed R #759017 on 2/20/2018 7:08 PM Last updated by kelsey m #935905 on 10/4/2019 1:02 PM Textbook Solutions 8950. Physical noise is interference in our environments, such as noises made by others, overly dim or bright lights, spam and pop-up ads, extreme temperatures, and crowded conditions. California State University, Fullerton • PUBH 415, Lecture 17 - Radiation pt II - FINAL (1).pdf, California State University, Fullerton • HESC 415, California State University, Fullerton • PUBH 201. Internal noise may be put into the following four categories. The signal to noise ratio is. 1. Yet the time it takes for the current carriers to move even a short distance is finite. Expert Answer . The movement of free electrons constitutes a current which is purely random in nature and over a long time averages zero. a. Physiological noise is a distraction caused by hunger, fatigue, headaches, medication and other factors that affect how we feel and think. The speed of the sound wave decreases. C) It is a term that describes the method through which people communicate messages. a. sound travel fastest at room temperature b.the hotter the midium the slower the sound travel c.the coder the midium the faster the sound travel d.the hotter the midium the faster the sound travel From equation (2), we see that the square of the rms noise voltage is proportional to the absolute temperature of le resistor, the value of the resistor, and the bandwidth over which it is measured. The sound waves produced by the speaker travel horizontally. What term best describes a louder version of a vesicular sound that can be heard over lung ... What term is used to describe a continuous type of adventitous lung sound heard loudest over the neck of the patient with upper airway obstruction? External noises, i.e. which of the following statements correctly describes the substance with the formula KI? If an object vibrates at a relatively high frequency, then the pitch of the sound will be low. Which of the following statements best describes CEMF? Atmospheric noise or static is caused by lighting discharges in thunderstorms and other natural electrical disturbances occurring in the atmosphere. B. Concept: Reflection of Sound - Echo. Electrons and "ions" strongly bound by molecular forces. Atmospheric noise accordingly consists of spurious radio signals with components spread over a wide frequency range. Concept Notes & Videos 305. a) Management has responsibility for maintaining and adopting sound accounting policies, and the auditor has responsibility for internal control. Which of the following statements best describes the distinction between the auditor's responsibilities and management's responsibilities? 6. Question Bank Solutions 7538.
