In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
Therefore, K can be determined a true constant. The pH of the solution does not affect the value of the equilibrium constant, K. K is a ratio of the concentrations of the products and the reactants. A change in pH is simply due to a change in the concentration of Hydrogen ions and hydroxide ions. A change in concentration merely causes a shift in equilibrium towards either the products or reactants. It does not however change the value of the equilibrium constant at constant temperature
So as long as there is enough HCl in the solution to react completely with the magnesium, the results should not change. However, if there is not enough hydrogen with a lower molarity, then the experiment will produce less hydrogen gas since not all the magnesium will be completely reacted. 8. How does Avogadro 's hypothesis relate to the results obtained in this experiment? Since the two trials of the experiment are done at a constant pressure and temperature, and about the same amount of moles of gas were produced, it makes sense that the volumes are around the same amount to.
According to your lab instructor, unhook the spring and remove the hanging mass from the centripetal force apparatus and determine the mass Hanging by using a balance. The radial indicator at the one extreme position. Used Vernier caliper to measure the diameter of the center pole, which is on centripetal force. Three times students have to measure the length of the pole, and at the end get an average. Students have to measure the distance between centers of the pole to the center of radial at the range of one.
Galvanometer has a word called sensitivity of galvanometer is defined as the current in micro ampere required to consume one millimeter deflection on a scale placed 1m away from a mirror. As with other formulas galvanometer has its own formula called a=the angle of deflection of the coil. Although, the currency of moving coil meters is dependent upon having a uniform and magnetic field. Is a very sensitive instrument used to measure the small currents of the order. Galvanometer gives the deflection which is proportional to the electric current flowing through it.
Theory: The principle we tested in this lab was Newton’s second law that states the net force on an object is equal to the mass of the object times its acceleration (F ⃗=ma ⃗). The formulas we used were: Δx=V_0x t+(a_x t)/2, we assumed the initial velocity V_0x=0 because it is extremely small, then we solved for a_x to get a_x=2Δx/t^2. a=gsin(θ). Experiment: The materials used in this lab were an air track, an air blower, a glider, computer, and wooden blocks. For table 1, my group and I started by making sure the air track was functional along with the motion detector if the air blower was working, and running the computer program for gathering data.
We timed the oscillation ten time and then found the average which was .77 seconds. We then used this information along with a formula to find the spring constant which we found to be 3,329.26 g/s^2. We then repeated this same experiment with a 100 g weight, and found the spring constant to be 3,580.8 g/s^2. Since these numbers are roughly the same, we know that our true spring constant is around these two numbers. Next, we timed the oscillation of a 100 g weight hooked onto a 29 cm string.
The dependent variable, which is the time taken for the empty muffin paper cup to touch the ground (immediately after it was dropped). This will be measured using a stopwatch, which will start when the paper cup is dropped, and stopped when the paper cup touches the ground. This will be done on table, preferably inside a science laboratory. (The table will be parallel to the muffin paper cup). Thus the measurements will repeat for each experiment, where the paper cup’s height from the ground varies in each
The experimental value yielded a result of y = -100x + 10 and the theoretical yielded a -100 V/m. The percent error between the two values was 0.00%. The experiment showed that the theory of the relationship between equipotential lines and electric field lines hold true. Introduction: The objective of this lab was to analyze the nature of electric fields formed by two dipoles and two parallel line conductors using a digital voltmeter. The purpose is to test the theory that states equipotential lines always run perpendicular to electric field lines.
4. Place the object precisely at the top of the projectile launcher, at 10 inches height and allow the object to properly glide down the slope until it is brought to a stop. 5. Use the stopwatch to calculate the time taken from the top of the launcher until it is brought to a full stop. 6.
