how is time‚ t related to the inclination of the track? Explain why? Time and position of velocity are interrelated to each other and the height and gravitational pull affects the acceleration of a moving and a free falling object. 3. From the data obtained‚ how would you account the difference between the picket fence’s acceleration and the value of g? The value of the slope of a graph of average velocity versus time will be the acceleration due to gravity of the falling object.

Mass Affecting Final Velocity Name: Anlin Pereira Class: 11C The lab was conducted on 24th September 2014 Teacher: Ms. Timlin Research question: How does the mass (grams) affect the final velocity (m/s) of the toy car on a one meter ramp? Aim: To carry out an investigation to prove that factors such as mass (grams) affects the final velocity (m/s) of an object as it travels a straight line and has a constant acceleration (m/s²). Hypothesis: It is predicted that the mass of the moving object

Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 Neurophysiology of Nerve Impulses 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. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain

a false truth to the word nerve. The courage it takes to have nerve is powerful‚ but having nerves is a weakness. A soldier in a battle needs confidence‚ and not worry or otherwise every action will be filled with doubt. The commander says‚ “No nerves‚ just have nerve out there.” The difference between the same word emphasizes the actual meaning of each word‚ creating it to be more heroic than a hero and braver than just the brave. One of the many definitions for nerve is “a person’s steadiness

The nervous system contains two general types of cells: neuroglia cells and a. nerves. b. cell bodies. c. neurons. d. nephrons. 2. The resting membrane potential of the neuron in this lab under the control conditions was _______ mV. 3. True or False: For most neurons‚ the concentration of Na+ and K+ ions inside and outside the cell are the primary factors that determine the resting membrane

EXERCISE 3 Neurophysiology of Nerve Impulses Laboratory Report Answer the following questions. (3 points each). 1. What is the difference between membrane irritability and membrane conductivity? Membrane irritability is the ability to respond to a stimuli and convert it in to nerve impulses. Membrane conductivity is the ability to transmit that impulse that is created by membrane irritability. 2. If you were to spend a lot of time studying nerve physiology in the laboratory‚ what

Abstract Purpose: Transcutaneous Posterior Tibial Nerve Stimulation (TPTNS) using adhesive skin electrodes is not commonly used due to its low efficacy. Our objective was to verify whether the combination of TPTNS with low dose Trospium chloride in the treatment of females with overactive bladder (OAB) would be more effective than TPTNS alone after failure of behavioral therapy. Materials and Methods: We randomized 30 women with OAB‚ into two groups‚ 15 patients each: Group I received 30 minutes

Neurophysiology has been a subject of study since as early as 4‚000 B.C. In the early B.C. years‚ most studies were of different natural sedatives like alcohol and poppy plants. In 1700 B.C.‚ the Edwin Smith surgical papyrus was written. This papyrus was crucial in understanding how the ancient Egyptians understood the nervous system. This papyrus looked at different case studies about injuries to different parts of the body‚ most notably the head. Beginning around 460 B.C.‚ Hippocrates began
