Initial expectations‚ in accordance with previous research‚ include: a correlation between severe nightmare distress and high absorption and thin boundaries; state factors‚ such as depression‚

Sounds are waves that we hear and are caused by vibrations that travel through mediums. Depending on the medium and temperature‚ the time it takes for sound waves to travel vary. The hypothesis states that if the temperature in the air increases‚ then the speed of sound will also increase because faster-moving particles transfer energy quickly. The data collected supports the hypothesis. Therefore‚ increased air temperature affects the speed of sound because the molecules move faster‚ which causes

In Echolocation: Volume Control by Amanda Tromans‚ she explains how some animals and machines use sound to locate things instead of using vision like others. For example‚ bats‚ dolphins‚ and submarines all do this but with a few differences. This paper is more like a review so it does not show specific steps. She explains in the beginning why those exactly use echolocation; this is basically the use of echoes and soundwaves. Those echoes and soundwaves are bounced off many objects so they can get

Application Note: CNT-91 + TimeView™ ABCs of Modulation Domain Analysis Background An instrument like an Oscilloscope lets you view voltage variations over time. A Spectrum Analyzer lets you view voltage variations over frequency. A Modulation Domain Analyzer (MDA) lets you view frequency variations over time. Figure 1 shows all three dimensions pictorially. To analyze all dynamic properties of a signal‚ all three of these tools are required: Oscilloscope (v vs. t) Spectrum Analyzer (v vs. f) Modulation

The research article I chose to analyze was When Moms Say Bad Words: Family and Peer Influence on the Frequency of Swearing by Emily Simpson‚ Joshua Duarte‚ and Brianna Bishop. I believe that the research study had good intentions on finding out the relations of whether families or peers have an influence on younger individuals when it comes to swearing. Especially‚ since in today’s society people are so much more open to swearing and kids at a young age are grasping on to it so easily that they

Laboratory Report 4 Experiment HN-2: The Electrocardiogram and Heart Sounds Exercise 1: The ECG in a Resting Subject Objective: To measure the ECG in a resting individual. Result: Questions and answers: 1. Is the amplitude of each wave (P‚ QRS‚ T) always the same in different cardiac cycles? 2. Which wave has the largest amplitude? 3. What is the average resting heart rate of the subject? Exercise 2: ECG Recording from Other Subjects Objective: To measure

Purpose: To investigate the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher

Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature

Tachyon particles are theoretical particles that supposedly have a minimum speed of the speed of light. Tachyons‚ (from the greek word ‘tachys’‚ meaning swift)‚ have never been found in experiments‚ but scientists think that they exist as faster-than-light “quasiparticles”. In the 1960s‚ some physicists wondered what would happen if matter could travel faster than the speed of light‚ something that is supposed to be impossible according to Einstein’s Theory of Special Relativity. Tachyons were first
