The design relied on two Schmitt triggers to generate the two different tones while using the transistors to act as a switch. This causes it to trigger continuously between two unstable states, allowing automatic switching between two frequencies producing two different tones. The RC values between the two Schmitt triggers will differ. Capacitors charge and discharge faster when it’s resistance is smaller.
Introduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.

From the data obtained in Tables 1-3, we were able to plot multiple graphs using excel. These graphs give a better representation of the data as seen in Figures 1-9. It can be seen that each figure shows a slight increase in CO2 production, which signifies a possible change in metabolic rate. Figures 4 and 7 show a relatively large change between the control and fox urine. The changes in slope between theses two are 0.0267 for Figure 4’s slopes and 0.0192 for Figure 7’s slopes.

Experiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component.

Suppose you need to find the fractional European call and the fractional European put options. Let the Hurst parameter be $H=0.85$, the $\sigma=0,25$, $r=0.10$, $S_{fbm} = 100$, $K = 95$, we have \begin{eqnarray*} d_1^{fBm} & = & \frac{\ln{\frac{S}{K}} + \frac{1}{2}(r( T - t) + \frac{(1)\sigma^2{( T^{2H} - t^{2H})}}{2})}{\sigma{\sqrt{T^{2H} - t^{2H}}}}\\ & = & \frac{\ln(\frac{105}{100}) + (0.10(0.25 -0) + \frac{(1){0.25^2}{0.25^{2(0.85)} - (1)0.25^{2(0.85)}}}{2}}{(0.25){\sqrt{0.25^{2(0.85)} - 0}})} \end{eqnarray*} we obtain $d^{fBm}_1= 1.0558$. We find in the normal distribution that $N(1.0558)= 0.8544$ and $N(-1.0558) = 0.1456.$
In the “Blast Off” lab, we had launched a foam rocket into the air by pumping air into a nozzle, shooting the rocket up, and then recording the time from launch to when it hit the ground. I have learned and now understand the mechanics of kinetic and potential energy. The experiment I had conducted relates to energy in that as we observed the rocket, its energy was constantly transforming as it was in motion. Kinetic energy is an object’s energy based on its motion. Potential energy is energy based on an object’s shape or position.
The mechanism that is compatible with the rate law that is calculated is rate=k[I−][S2O8^ 2-], which matches with the b) mechanism. It starts with the slow step, which is the rate determining step and it also states that the rate law equals to rate=k[I−][S2O8^ 2-].

The system was run with the power filter, then the fish were introduced to the system. The plants were then installed after two days. The BioMax insert was removed because the plant would replace it. The plant was held up by a sponge insert sitting on top of the activated carbon. The fish were fed and the plants were observed daily.
This paper describes design and fabrication of air conditioning system that uses solar evaporation to obtain cooling. The basic idea was to design a system that is affordable, consumes less energy and gives the same effect as that of the conventional air conditioner. This system provides satisfactory results. The only disadvantage observed; is long time required to get the desired cooling effect. Keywords: Solar Evaporation, evaporative cooling, water level sensor ---------------------------------------------------------******------------------------------------------------------------ 1.
This trend may put further strain on the environment and natural resources. Ultimately, the impact of cooling systems is obviously a serious issue. however, professionals and architects must address it and continue to develop greener effective ways to combat environmental damage and keep indoors
