Lab Sheet 1. In the lab activity‚ you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button‚ then the train will move) If the sound source is moving‚ as it get closer to the person it will get louder and the farther away it gets it starts to fade. 2. Select the boy icon. Select the lowest pitch by selecting

Typical guns expel microwave waves off to the atmosphere while the gun is directed to hit towards a target From there‚ an object moving by who hits it sends the waves back with its modified frequency caused by the Doppler Effect (Georgia State University‚ “Police Radar”). This effect essentially changes the receiving waves from the radar because it bounces back from an object with changing distance from the radar by having speed. These variables then cause disturbances in the waves in which it

| SPEED DETECTION USING DOPPLER EFFECT AND RADAR | | | INTRODUCTION Although there is good road safety performance the number of people killed and injured on our roads remain unacceptably high. So the roads safety strategy was published or introduced to support the new casualty reduction targets. The road safety strategy includes all forms of invention based on the engineering‚ education and enforcement and recognizes that there are many different factors that lead to traffic

Activity 2: Investigate how businesses develop. In this report I am going to compare and contrast my two businesses‚ Disney and Adventure Island. I will also outlines whether the market for their goods and/or services are steady‚ declining or increasing and then I will also include suitable maps identifying the location of Disney and Adventure Island and evaluate the likely reasons for their choice of location. I will then evaluate what factors might cause Adventure Island to relocate. Markets

ulcers ranged from 9-22% of the total workload. Douglas (2001) informs us that leg ulceration affects around 1% of the population. This evidence has provided the author with a rationale to review the literature regarding the contemporise issue of Doppler assessmenDts with an aim to measure the reliability and validity of this type of clinical procedure. Learning outcomes to be met will be indicated in bold lettering at the end of each appropriate paragraph. In order to practice competently nurses

Investigate the effect of on exercise on the heart rate. Aim: To find out if there is any relevant link between the amounts of exercise taken to increase a person heart rate. Equipment needed: Stop watch Screen volunteer P.E kit Calculator Record sheet Type of exercise: skip for few minutes ‚ then break in between and again repeat it once or twice. Method: First of all‚ we needed to take the resting heart rate of the person who is about to skip. Then‚ with the stopwatch one

Investigating the effects of Caffeine on the heart rate of Daphnia Shrimp. Aim: In this experiment we are trying to find out how varying the concentration of caffeine can affect the heart rate of Daphnia shrimp. Prediction: I predict that caffeine will increase the heart rate of the shrimp . Introduction: I believe the results will comply with my prediction. Caffeine is a compound found in especially tea and coffee plants and acts as a natural pesticide. Caffeine is a central nervous system

Investigate the Effect of Acid Rain on Building Materials Question: What is the effect of 6M sulfuric acid (H2SO4) on the corrosion rate of the 3 grams of steel as the amount (number of sprays) of sulfuric acid increases? Variables: Independent variable: the number of sprays of 6M sulfuric acid (0‚ 5‚ 10‚ 15‚ 20‚ 25 times) to observe its effect on the corrosion rate. Each spray will contain about 10mL. Dependent variable: The corrosion rate. It will be calculated by measuring the mass of steel

of Christian Doppler There have been many great discoveries in all studies of science and more are yet to come. A mathematician and leading physicist of the 1800s‚ Christian Doppler has definitely enriched the field of science through his discovery. The discovery that Doppler found is called today the Doppler Effect. His perseverance and ambition has taken him a long way to success. All of these qualities have been able to be seen right from his childhood years. Christian Doppler came from a stonemason

Experiment to investigate the effect of concentration of electrolyte on the current of voltaic cell Aim The aim is to identify the relationship between the concentration of H2SO4 solution and the current of Cu-Zn voltaic cell. Hypothesis My hypothesis is that the greater the concentration of sulfuric acid the bigger the current of the voltaic cell. In a voltaic cell‚ chemical energy is concerted to electrical though the oxidation and reduction happen on the electrodes. Current will not flow
