OBSERVING WAVE PULSES - EXPERIMENT 15 PART 1 - Transverse Wave Pulses Q1 - As the pulse travels down through the spring‚ its‚ size and amplitude is reduced - the sizes of the waves are much smaller as the forces become weaker (losing energy) as the distance from the point of initiation is increased. Q2 - Pulses do not ’catch up’ with one another in transverse waves. They either meet at a certain point momentarily or pass through each other and continue on their way as if nothing has happened.

Lab#: 15 Title: Exercise/pulse rate Aim: To investigate the effect of exercise on the pulse rate Materials/ Apparatus: Stop watch Diagram: Procedure: 1. The three middle fingers were placed just behind the bottom of the wrist as indicated in the diagram in order to see if the pulse could be felt. 2. (a) If the pulse was not felt the three fingers were moved about until it could be felt. (b) Changing the hand also helped to find the pulse. 3. The number of pulsation

Effect of Exercise on Pulse Rate and Blood Pressure Purpose: To determine the effect of jogging on pulse rate and blood pressure. Hypothesis: If you jog then your heart rate and blood pressure will increase. Materials: Tape Measure Blood Pressure Cuff Procedure: 1. Record resting blood pressure and heart rate. 2. Measure out 100m. 3. Jog 100m (same speed every time) 4. When finished jogging 100m record heart rate and blood pressure. 5. Repeat steps 3&4‚ 3 more times 6. Calculate average

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

beat is stronger in the neck it is sometimes more difficult to locate and so most people tend to measure it from the wrist. For a healthy person of my age a pulse rate between 60 and 100 is considered to be normal. When I was at rest my heart rate was 82 bpm (Beats per minute). This could be inaccurate due to being nervous though I took my pulse reading both manually and on a machine and it came back the same both times‚ which may increase the reliability of the

time. Increasing bad cholesterol and bad blood circulation are leading to many common diseases. An early walk in the morning could be a good solution to cater these issues. The earliest hours of a day could probably allow us to watch the natural sceneries at their maximum charm and get the fresh oxygen to our mind and body as the temperature of the day is at its best during morning hours and the pollution would be less as compared to later time of a day. An early walk also provides good amount
