EXPERIMENTAL DATA: Table 1: Measured values from experimental data Resistor Measured Value 101 Ω Capacitor 1 μF Amplitude of voltage 5v Phase difference 58.752º Peak to peak voltage 10 v Amplitude of current 2.53 mA ANSWERS TO THE POST LAB REPORT: Q. 1. Dividw the amplitude of the signal generator voltage measured by the oscilloscope by √ and compares it with the measured value by voltmeter. Answer: Here given, Vm = 5 V Dividing Amplitude of voltage Vm by √2, 5 √2 = 3.54 Comment: Both values were not matching. There have more than 10% discrepancy.

In each part of the experiment, you will be observing a different property of electrolytes. Keep in mind that you will be encountering three types of compounds and aqueous solutions: Ionic Compounds These are usually strong electrolytes and can be expected to 100% dissociate in aqueous solution. Example: NaNO 3 (s) → Na+(aq) + NO 3 –(aq) Molecular Compounds These are usually non-electrolytes. They do not dissociate to form ions. Resulting solutions do not conduct electricity.
Buoyancy Lab Report I. Theory: In this experiment, we are trying to prove a theory that buoyancy is a force exerted by a liquid, in this case water, which opposes an object's weight. The theoretical buoyant force is given by FB=ρgV with ρ is density (kg/m3), g is gravitational acceleration (m/s2), and V is volume (m3).To measure the buoyant force, we compare the weight of an object in and out of the water by FB=Wout – Win. The simplifying assumptions are no surface tension, no friction, no air resistance, and gravitational acceleration is constant at 9.8m/s2. II.
physioex 9.0 Review Sheet Exercise 3 Neurophysiology of Nerve Impulses Name _Jasmine Talley________ Lab Time/Date __11/6/13____ Activity 1 The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. By increasing the extracellular K+ there is efflux and also influx into the cell which increases the tendency of the cell to depolarize.___ 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your prediction?
