Samantha Mackey 13. 2nd hour PHYSICS LAB REPORT: SPEED OF SOUND Purpose: In this lab‚ we will be doing 3 major things: 1) Collecting and organizing data to obtain resonant points in a closed pipe‚ 2) measure the length of a closed-pipe resonator‚ and 3) analyze the data to determine the speed of sound. Procedure: 1. Fill the graduated cylinder nearly to the top with water‚ with a tall glass tube open at both ends (the water level with act as the closed end). 2. Determine

What exactly is an absolute threshold or difference threshold? In this paper‚ I will experiment these two thresholds‚ go in depth of what exactly they are‚ and I will also contrast. I will first talk about absolute‚ then work my way into difference. Each one of our bodies organs have what is called sensory receptors‚ which detect stimuli from the outside world and process it so that the braid can comprehend. These receptors can be found in such places as the eyes‚ ears‚ nose‚ and mouth. Hints the

that can be gathered through an acoustic profile. The Visi-Pitch is a very useful tool for speech language pathologists (SLPs)‚ as it can provide them with information regarding clients’ habitual pitch‚ vowel quality‚ and phonation abilities. A huge advantage of this software is that SLPs can use it with a variety of clients‚ those including voice‚ articulation‚ fluency‚ and accent modification. The information gathered from the Visi-Pitch can be useful in assessment‚ developing treatment goals‚ and

Elevator Pitch You are standing at an elevator‚ waiting. The person you want to pitch your short-term financing proposal to walks up and stands beside you. You introduce yourself and say that you are getting ready to pitch them. They give you the Oh-and-why-should-I-pay-attention-to-you? Look. The elevator doors open and you both enter. You have about 45 seconds to capture their attention and give them a set of reasons to pay attention. This is called an elevator pitch and you must‚ at all times

pitch and tempo for effective presentation If you’re male‚ your voice will have a lower pitch than most of your female friends. If you are very slender‚ you will probably not have as much vocal resonance as someone with a larger chest cavity. But don’t despair. There are many features of your voice that you can change with a little practice and if you are going to be giving a presentation‚ a little bit of vocal warm-up may be all the practice you will need to sound dramatically better.

The concept of the Elevator Pitch is borne from the idea that if you met an investor on an elevator and only had 30 seconds to pitch your business‚ what would it sound like? In fact 30 seconds is about as much attention as you are going to get from an investor to begin with‚ so thinking in that time frame makes a lot of sense. The formula for the perfect Elevator Pitch involves three ingredients - the Problem‚ the Solution‚ and the Market Size. The Problem Every great company starts by solving
