SPH3UC – Lesson 1 1. A) Amplitude is the distance between the equilibrium and the maximum displacement. In this wave‚ it would be from the equilibrium to the top of the crest or bottom of the trough. B) C) Speed: m/s Frequency: Hz D) Speed: because speed is constant and not affected by the change in frequency. Wavelength:0.4 Hz. 2. In transvers waves the motion of the particles is perpendicular to the direction of the energy. In longitudinal waves it they are parallel

PHYSICS WORK SHEET - 2 CLASS – IX LESSON : MOTION 1. Analyze the following situation and answer the following questions. A circular track has a circumference of 3140m with AB as one of its diameter. A man riding a scooter moves from A to B along the circular path with a uniform speed of 10 m/s. a) Distance covered by the man b) Displacement of the man c) Time taken by the man in reaching from A to B. 2. A car starting from rest moves with a uniform acceleration of 0.1 m/s2 for 2 minutes. Find the

What is sound? Sound is a wave‚ a pattern—simple or complex‚ depending on the sound—of changing air pressure. Sound is produced by vibrations of objects. The vibrations push and pull on air molecules. The pushes cause a local compression of the air (increase in pressure)‚ and the pulls cause a local rarefaction of the air (decrease in pressure). Since the air molecules are already in constant motion‚ the compressions and rarefactions starting at the original source are rapidly transmitted through

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

6th hour 4/1/13 Tennis ball and racket ball comparison Problem: Find the speed of the tennis ball and the racket ball to determine which one travels faster. Hypothesis: I believe that the racket ball will have a faster average speed than the tennis ball for both distances because the racket ball is bouncy. Materials: *Tennis ball *30yards of space *Racket ball *Set of stairs *Stop watch *measuring tape Procedures: 1) Measure out 30 yards of space‚ have of member stand

Chapter one of Healing at the Speed of Sound‚ by Don Campbell and Alex Doman‚ brings up some interesting ideas for the reader. Whether you believe them or not‚ it is important to evaluate and discuss their ideas expressed. The first interesting idea brought to my attention is an idea I would say I was subconsciously aware of‚ but never fully incorporated into my everyday life. Campbell and Doman express that the sounds you hear affects your mood‚ energy and others aspect of your life. They go on

Measuring the Speed of Sound (Moving Tube) KEY Purpose: To measure the speed of sound in air using a variable length column of air. Apparatus: resonance-tube apparatus (an open ended tube which can be moved in and out of a container of water) constant frequency source (tuning fork or computer generated tone) rubber hammer meter stick rubber stopper Procedure: 1. Set Up the Experiment: Place the open ended tube into the water‚ and verify that it can produce a resonance tube

objects with different masses to fall equal distances was equal. 2. The average speed of the two different masses was quite similar‚ within one tenth of a second of each other. 3. Yes‚ because physics theory says that objects free falling‚ where the only force acting on them is gravity‚ accelerate at the same rate no matter what their mass is. 4. The change in spacing of the dots tells us that the speed of the object is increased as it falls‚ because the spacing increases between the dots
