Lab Exercise 2: Acceleration A. Objective This experiment will provide data to calculate the acceleration of a marble as it rolls down an incline plane over measured periods of time. To do this‚ the marble’s velocity will be determined and then its acceleration. 1. What is the distance between two marks in your inclined plan? -50cm 2. What is the angle of your inclined plan with respect the horizontal? -16degrees 3. Newton’s first law says a body at rest will remain at rest unless

1. Lab 8: Input Validation This lab accompanies Chapter 7 of Starting Out with Programming Logic & Design. Name: Devin Hill‚ Matt March‚ and John Meno Lab 8.1 – Input Validation The goal of this lab is to identify potential errors with algorithms and programs. Step 1: Imagine a program that calls for the user to enter a password of at least 8 alphanumeric characters. Identify at least two potential input errors. -Password contains a symbol -Password has less than 8 charecters Step 2:

PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 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 predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability
