Luckily, there are medicines, called antacids, which can help relieve heartburn pain. Antacids essentially work by increasing the pH of the very acidic stomach acid. They don't need to raise the stomach acid pH all the way to a neutral pH of 7, but just raising the pH to 3 or 4 will make a person feel better.
Calculate the AMA of the ramp below. Show your work. 6. The efficiency of a machine can be determined by the following equation. efficiency = actual mechanical advantage x 100 OR (Work Out) / (Work In) x 100 ideal mechanical advantage efficiency = AMA x 100 IMA 6a. Determine the efficiency based on the diagram below. Show work.
Exercise 5: What is the efficiency of a machine that has work inputof 40 joules and work output of 35 joules? Exercise 6: Work output of a large machine in a factory is 89,000 joules, and its input is 102,000 joules. Pearson Education, Inc., publishing as Pearson Prentice Hall. All rights reserved. Section 14.3 Mechanical Advantage and Efficiency Efficiency Because some of the work input to a machine is used to overcomefriction, work output is always less than work input.
