Investigating The Wave Speed Of Traveling Waves On A String That Was Bounded On Both Sides

F. How did the magnet’s density measurement using the Archimedes’ Principle compare to the density measurement using the calculated volume? Which method might be more accurate? Why?

The purpose of this experiment is to measure the speed of sound in air and to determine the effects of frequency on the speed of sound.

The main purpose of the lab is to study the two basic waves along with, their properties. The results we got were diverse from each other. The longitudinal waves compress than stretches to become a rarefaction. However, with the transverse waves, the medium was much slower when it was moving up and down. The only similarity that the waves share is that the energy travels through the slinky

To begin the experiment, we measured the masses of the two stoppers and the eye bolt used to secure the stoppers that we were using in our apparatus. The mass of the first stopper was 18.8 grams and the mass of the second stopper was 50.5 grams. The mass of the eye bolt was 11.6 grams. The mass of the screw and bolt that secured our hanging mass was given to us as 25 grams. After, we chose six different hanging masses based on stopper mass. We made sure that the hanging mass was always larger than the stopper mass or else we would not be able to get the stopper to spin at a constant velocity. The first three mass ratios we chose was using the stopper with the mass of 18.8 grams and then we used a hanging mass (the mass of the screw and bolt is included) of 65 grams, 85 grams, and 105 grams. This gave the three mass

After collecting data and analyzing the results the group concluded that tension will always be greater than mass for uniform constant motion due to the presence of θ. As the length of the string for the flying toy increased, θ decreased in both trials for the cow and bat. For instance, when the bat had a length of 0.86m, the calculated θ was 34.4°, but when the length was shortened to 0.61m, the θ increased to 36.5°. The period was also shortened when the length decreased; therefore, velocity decreased as string length increased while acceleration increased with a

-“The wave disturbance travels 300 m for each wavelength.” The speed of the wave does not determine how long the wave disturbance travels for each wavelength. We do not have enough information to determine that.

In this experiment in a low speed flow the static pressure around an aerofoil will be observed and discussed. The lift on the aerofoil will also be calculated and compared with the theoretical value. The aerofoil being used in this particular experiment is symmetrical and is taking place in a wind tunnel with a speed of 18.5m/s, therefore the flow is assumed to be incompressible. The different pressures along the surface of the aerofoil will be measured at an angle of attack of 4.1 degrees and 6.2

Record the amplitude and corresponding period of vibration for one oscillation, followed by the sixth oscillation.

As a class, we got our solution. The weights for the individual hay bales are 39, 41, 43, 44, 47. Here are some

Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)

As a result of trail and error method we find the angle for the third pulley and the mass that should had be suspended from it. This will balance the forces deployed on the strings due to the other two masses. While the third force is defined as the equilibrant (������⃗������) Since it is the force that establishes the equilibrium. It is also the negative of the resultant -������⃗������ = ������⃗������ = ������⃗ ������ + ������⃗������. We gathered and recorded the mass and the angle required for the third pulley to enable to put the system into the equilibrium in table 1.

Table 1 & 2: First, find the mass of the wooden block and record the data. Then place the wooden block on the inclined plane (at 0o) with the wide side down. The height of the pulley should be the same height as the screw location on the wooden block. Then hang a weight on the opposite side of the hanger and add weights until block starts to move with a constant velocity (push block to overcome fs¬). Then record the resulted weight of the hanger in Table 1 (as F). Add 500 g to the wooden block and repeat the process. Replace 500 g with 1 kg on the wooden block. Repeat the process described above.
