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.
Efficiency is the percentage of output to input. Like you gave a horse grass to run 100 km, but it ran 50km with that grass, than the horse is 50% efficient. In terms of human hardwork, efficiency has a formula, the one above, but can't be calculated exactly. It's how much output you gave as compared to the input you put and the resources you utilized. Performance on the other hand is a measure of the quality of output. If two horses are given grass to run 100km, but both run 50km.
