A refractory period is a period of time where the cells are resistant to depolarisation. There are 3 different refractory periods‚ firstly the absolute refractory period which is the part of the cardiac cycle where no further depolarisation can take place. Secondly it is the relative refractory period where depolarisation of the cells can occur but only if the stimulus is strong enough‚ and finally there is the diminished refractory period where the cells are still resistant to depolarisation but

Unit: Sinusoidal Waves Subject: Advanced Algebra/ Trigonometry Overarching Question: What are real life applications of Sinusoidal Waves? First and Foremost‚ Sinusoidal Waves are waves that can be described to have a sine curve‚ usually repetitive. Sine waves are a part of the mathematic topic‚ Trigonometry. However‚ these types of waves may be found in various other scenarios. For instance‚ many are found in nature‚ you just have to observe with care. This means to say that they aren’t just

Beginning Vibration Analysis with Basic Fundamentals By: Jack Peters Beginning Vibration Introduction Understanding the basics and fundamentals of vibration analysis are very important in forming a solid background to analyze problems on rotating machinery. Switching between time and frequency is a common tool used for analysis. Because the frequency spectrum is derived from the data in the time domain‚ the relationship between time and frequency is very important. Units of acceleration‚ velocity

ACTIVITY: THE CAT’S MEOW / MILK CO-MOTION PURPOSE: To observe the interaction of detergent with the fat of the milk and food color 1. Provide a possible explanation of phenomenon you observed based on the result of your experiment. When food color is added to milk‚ it floats because it is less dense than milk. The non-polar fat in the milk prevents the food color from spreading‚ as it cannot participate in hydrogen bonding with water. When detergent is added to milk and the food color‚ the

Act I Scene 1 Homework – Graphing a Wave Name: A vibration is a wiggle in time; a wave is a wiggle in space and time. In this exercise‚ you will explore that connection by transferring the motion of the second hand of a clock (a vibration‚ even if a slow one)‚ to a wave. Print out the image of a clock and open the spreadsheet called Grapher. You will find both of them in the same item where you found these instructions. Use a metric ruler to measure the displacement of the tip of the

Observable phenomena related to the moon: - phases of the moon: depending on the Moon�s position relative to the Sun‚ we see different parts of the illuminated Moon. - the month:� Moon changes through a complete cycle of phases in about 29.5 days - eclipses To understand these phenomena‚ we have to change our perspective and think about the Moon�s orbit. Some properties of the Moon: Radius 356‚000 km 407‚000 km 15% change from max to
