3.I was wondering if you could help me with some Linear Motion Physics Problems. For the first question, I completed
n, I completed parts A and B, but can't get C. We get all the answers to the questions but not how to get to the answer. The question is:
Patrick changes velocity from 2.0 m/s North to 4.0 m/s South with an acceleration of 0.50 m/s/s South. (A) Determine how much time this process takes (ANSWER: 12 s). (B) Find his displacement (magnitude and direction) (ANSWER: 12 m South). (C) Find how much distance Patrick covered (ANSWER: 20 m).
Another question I was having trouble with was this (I got part A but not parts B or C):
Two cars are traveling along a straight line in the same direction, the lead car at 25.0 m/s and the other car at 30.0 m/s. At the moment the cars are 40.0 m apart, the lead driver applies the brakes, causing his car to have an acceleration of -2.00 m/s/s. (A) How long does it take for the lead car to stop? (ANSWER: 12.5 s). (B) Assuming that the chasing car brakes at the same time as the lead car, what must be the chasing car's minimum negative acceleration so as not to hit the lead car? (ANSWER: -2.29 m/s/s). (C) How long does it take for the chasing car to stop? (ANSWER: 13.1 s).
5.I was wondering if you could help me step up my chem problems, i'm not sure how to begin
estion 1: Draven collected a 1ml sample from a local river. Draven added 99 ml of water to the sample. Draven then took 5 ml of the diluted sample, and determined the 5 ml sample to contained 10 mg of sodium chloride. what is the concentration of sodium chloride in the river?
question 2: how many grams of H2 could be produced when 13 g of H202 decompose?
question 3: how many molecules of carbon dioxide could be produced when 25 ml of a 0.8 M ethanol, c2h60, combusts with 5.18X10^23 molecules of oxygen? the unbalanced equation for the combustion of ethanol is given below:
7.Hi there, I was wondering if youd be abl to help me here... this is more neuroscience i believe but
I am in desperate need of help. There questions are in accordnce wih the AUDITORY CORTEX 1. How is sound intensity encoded? (I am not sure if these means how is it measured...?) What is a rate level function? What is the tonotopic map of the cochlea? What is a tuning curve ? What is the best frequency? What is the threshold ? What is the Volley Theory? I have an idea of the material since it was review in class but the PowerPoint slides are hard to understand. 2. Describe the concept of sound localization and the coincidence detection model of binaural processing occuring in the superior olivary nucleus that mediates sound source localization? (I don't even know where to start with that one) 3. Distinguish between the neural circuit processing intetnaural time differences intetnaural level differences? How and where are the signals compared? (I understand the level vs time difference but I do not know about the neural circuit processing... And what does it mean by where are the signals compared?) 4. Understand the gross organization of the auditory cortex: primary AI and secondary AII auditory cortex, tonotopic organization. I am using the textbook brain and behavior 4th edition by Bob Garrett and also the review PowerPoint slides given to the class but it is mostly charts and graphs
