Purpose: The purpose of this lab is to test what substances are necessary for muscle contraction. Hypothesis: Based off the frog muscle immersed separately in Solution A of ATP and distilled water solution‚ Solution B of ATP with KCl in distilled water and MgCl2 in distilled water and solution C of KCl and MgCl2 in distilled water‚ I hypothesize that solution B of ATP with KCl in distilled water and MgCl2 in distilled water will cause the muscle to contract. Introduction: This lab consisted of

Laboratory – Terminal Velocity Introduction: Consider dropping a piece paper and a brick from the same height. Although in theory they should both strike the ground at the same time; in practice the brick will always strike the ground first. The reason is because of air resistance. As the paper falls to the ground air resistance is pushing the paper up‚ this slows the acceleration of the paper. It is known that as the velocity of an object increases the air resistance acting on the object

PROJECTILE MOTION PRACTICE QUESTIONS (WITH ANSWERS) * challenge questions Q1. A golfer practising on a range with an elevated tee 4.9 m above the fairway is able to strike a ball so that it leaves the club with a horizontal velocity of 20 m s–1. (Assume the acceleration due to gravity is 9.80 m s–2‚ and the effects of air resistance may be ignored unless otherwise stated.) a b c d e How long after the ball leaves the club will it land on the fairway? What horizontal distance will the ball travel

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.

Where Do You Feel Contractions? During labor‚ your uterus contracts its powerful muscles and your cervix softens and widens to allow the birth of your child. Where do you feel contractions? You feel the tightening of your uterine muscles as the uterus pulls upward and pushes your baby down your birth canal. These contractions‚ which consist of shortening and tightening of the muscles at the top of the uterus can cause a lot of pain and discomfort. Each mother-to be may experience pain differently

Eskom’s ‘Load shedding’ Our community seems outraged by Eskom. People feel that because they paying for their power then why should they save? Yes it is Eskom’sfault that they never placed a power back up system but we do have to live with it for a while unfortunately. However Eskom does claim that they are doing everything possible in order to accommodate everyone. People are saying though that they are not living up to any of their promises made in the beginning. In fact many claims and promises

Electricity load shedding in Pakistan has increased manifold. Minister of water and power Raja Pervaiz Ashraf assured that electricity load shedding would be done according to time schedule. He assured that electricity load shedding will finish by the end of the year 2009 but instead it is doubled what it was in the past year 2009. It is big failure of the government of Pakistan. No country can make progress without electricity. Recent government measures of holiday on Saturday and other saving methods
