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.
Principles of Simple Machines: Machines simply transmit mechanical work from one part of a device to another part. A machine produces force and controls the direction and the motion of force, but it cannot create energy. A machine's ability to do work is measured by two factors. These are (1) mechanical advantage and (2) efficiency. Mechanical advantage. In machines that transmit only mechanical energy, the ratio of the force exerted by the machine to the force applied to the machine is known as mechanical advantage.
