Title: Measuring the speed of sound. Research question: How to determine the speed of sound by using the relationship between the frequency of the signal generator‚ f and the length of air column in the tube‚ l . Variables: Manipulated | Frequency of the signal generator‚ f | Use different frequency of signal generator which are 1000Hz‚ 1400Hz‚ 1800Hz‚ 2000Hz‚ 2500Hz‚ 3000Hz and 3600Hz. | Responding | Length of air column in the tube‚ l (±0.5cm) | Measure the

about the acceleration of body? (a) Positively accelerated (c) Uniform accelerated (b) Negative accelerated (d) None of the above [1] 2. What does slope of position time graph give? (a) speed (b) acceleration (c) uniform speed [1] (d) Both (a) and (c) depending upon the type of graph. 3. When a body moves uniformly along the circle‚ then:(a) its velocity changes but speed remains the same (b) its speed changes but velocity remains the same (c) both speed and velocity changes (d) both speed and velocity

English 1010-001 Speed Kills? They use the slogan “SPEED KILLS” to brainwash the American public into conformity with the insanely-low speed limits that benefit the insurance companies‚ local governments‚ and all others who profit from them. The arguments that are used to support this ideal are based upon faulty‚ self-serving‚ and biased science. Speed does kill‚ but only if the vehicle runs into something. The speed limit is set deliberately 10-15 mph below the average driving speed on urban highways

The point where the centripetal acceleration is provided completely by gravity is when the centripetal acceleration is equal to the gravity. This happens at the point where h=r/2. As the truck moves from point A to point B‚ it would have decreased in height by r. Applying this again to our equation‚ we get; Hence‚ Using this in our g-force equation‚ we get; And so the rider experiences an additional 2g of centripetal force from that experienced at the top. Later‚ as the tuck moves to point

Finding the Acceleration of a Ball Problem Statement: How does the height of a ramp that is comprised of two parallel rulers affect the speed of a steel ball bearing rolling down it? Hypothesis: If the steepness of the ramp based on the amount of books propping it up are increased‚ then the steel ball bearings’ speed will increase. Materials: 2 wooden meter sticks 1 steel ball bearing 5 workbooks A roll of masking tape A stopwatch A smooth‚ long surface (preferably a table) Procedures: Arrange

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

Electromagnet even stronger?! To make the magnetic field even stronger‚ you need to apply more current to the circuit. SPEED! Speed is the velocity the object is travelling at. It can be measured by KM/H‚ MP/H‚ MP/S etc. It’s basically how far the object travels in a certain time. The equation for speed is: Speed=Distance÷Time. Distance=Speedxtime. Time=Distance÷Speed. ‘The space shuttle will travel the first 50‚000km of its journey in 2 hours. It will complete the second stage of its journey

Speed dating is today a social and commercial phenomenon among other ways to find a mate in our busy and global society. It paradoxically began in 1999 with the Rabbi Yaacov Deyo who invented this system to allow single Jewish men and women to meet in a safe‚ chaperoned environment and therefore facilitate weddings in Los Angeles. How does it work? It is organised in parties that take place in clubs or restaurants and cost between 30 and 80 dollars. 10 to 25 men and the same number of women (usually
