Tangential Velocity Lab Report

How does the acceleration in Data Table 2 compare with that of Data Table 1? Why do we observe this difference? In data table 1 the rate of a_calculated was 2.829 m/s2 and table 2 was 4.77m/s2. The acceleration in the first table would be less than table two due to the fact that less mass is added to the hanger.

The T table value is 1.0371. This number’s close proximity to 0 concludes that there is no significant difference in the number of coacervates. o we reject the alternative hypothesis, and accept the null. The strengths of this experiment are that there was the ability to test size and number in the same process.

The result of the force acting causes the object 's velocity to either change speed or direction. In conclusion, the impulse experienced by the object equals the change in momentum of the object, which can be seen in equation Ft = m Δ

This does not occur with every collision, so certain methods are used to increase the probability of a successful collision, and thus increasing the rate of reaction. One of these methods is increasing the concentrations of the reactants. Increased concentrations results in particles colliding more frequently, and more successful collisions will occur. On a graph, there would be a decreasing curve as the concentrations of reactants decreases as the reaction

Molar mass is the mass in grams in one mole of substance. The units for molar mass are in grams per mole. Molar mass is the same number as the formula mass that needs to be found except it is converted. Formula mass is the mass in atomic mass unit of one particle of

The vibrational energy of the molecule will have increased by E after tunnelling. To reiterate, only when the difference in energy levels of the donor and acceptor is equal to the molecular vibrationsal energy, E, tunnelling occurs. Thus, the receptor detects a single well-defined energy, E, making it operate as a spectrometer. Only a molecule with the right vibrational energy present in the gap causes a tunnelling current to flow across the device, a prerequisite being the change in energy between the donor and acceptor levels being sufficiently large. The relative strengths of the coupling affects which state(s) will get excited if there are many vibrational modes.

Newton 's first law states that a body at rest stays at rest and s body in motion stays in motion unless after upon by an unbalanced force (inertia). In this case, the unbalanced force is rolling friction, and it always stayed the same throughout this experiment. What changed, was the container released from the taller ramp had more GPE, more Kinetic Energy, and more inertia, which caused it to go further up the ramp than the lower one released from the lower ramp, with less GPE, and less

On the other hand, the magnitude can be derived as follows. Figure 1 depicts the initial and final vectors when an object traverses at constant speed around a circle with radius r. Extracting these vectors and applying the head to tail method of adding vectors, we see that we will form two similar

This can require an extra hand to help in the

This is the diffusion of the particles. The greater the difference in concentration, the faster diffusion will occur because there are more chances of collision, thus, more chances for the particles to diffuse down their concentration gradient. It is also worth noting that the speed of diffusion is greatly influenced by particle size and temperature. Simple diffusion is unassisted and it does not require energy. This is when nonpolar and lipid soluble substances diffuse directly through the phospholipid bilayer without any help.

As explained earlier in the Literature Review, a lower current results in a smaller amplification of sound. 3.3.3 Capacitors Since the resistor values remained fixed, the capacitor values were manipulated in order to attain the desired frequencies. C1 – 100uF The above capacitor is responsible for generating the square wave and the duty cycle.

The effect of the solution concentration of sodium chloride on diffusion in yam cores compared to the solution concentration of water Abstract The purpose of the experiment was to see if different solution concentrations had an effect on diffusion. Our group established a hypothesis that stated; sodium chloride will make the yam cores weigh less than in water. In order to start experimenting, we obtained 10 yam cores, weighed them and placed them in five cups that contained 50 mL of water.
