Why is motion in one dimension the simplest form of motion?
Why is motion in one dimension the simplest form of motion? 2.0 One-Dimensional Motion One-dimensional motion means moving forwards and/or backwards along a straight line, and is the simplest form of motion to study. The core of learning this is understanding rates, which is how any quantity changes over time. Key rates we will study […]

What is the leak rate threshold for comfort cooling appliances?
What is the leak rate threshold for comfort cooling appliances? Owners/operators must identify and repair leaks that exceed 30% for IPR, 20% for commercial refrigeration, and 10% for comfort cooling and other appliances within 30 days of when the ozone- depleting refrigerant is added. Leaks must be repaired such that the leak rate is brought […]
Which property of water makes it more useful as a coolant in sweating?
Which property of water makes it more useful as a coolant in sweating? Water’s thermal properties, its high specific heat, means that it can cool us Evaporating sweat (water changing phase from liquid to gas) takes heat away from the body Water is also the main component of blood plasma. It transfers heat from the […]
