What happens to your body after plane crash? When there is an explosion that tears a big hole into the plane and the cabin’s little bubble of pressure is suddenly burst, something called “explosive decompression” takes place. Basically, the pressure difference comes rushing at your body so fast that it tears your body apart. Do […]

What is sensible heat ratio? “SHR” stands for “Sensible Heat Ratio” and it is a way to determine how much of the total capacity of an HVAC unit is used for sensible cooling versus latent cooling. meaning only 20% or 30% of the capacity of the unit is available for controlling latent heat. What is […]

Is MRI or CT better for brain? Magnetic resonance imaging produces clearer images compared to a CT scan. In instances when doctors need a view of soft tissues, an MRI is a better option than x-rays or CTs. MRIs can create better pictures of organs and soft tissues, such as torn ligaments and herniated discs, […]

What happens to kinetic energy during boiling? The kinetic energy of particles increases until the liquid reaches its boiling point. At the boiling point, the potential energy of particles begins increasing. The particles move farther apart until the attractive forces no longer hold them together. At this point, the liquid changes to a gas. Does […]

What are the limits of classical physics? The classical limit or correspondence limit is the ability of a physical theory to approximate or “recover” classical mechanics when considered over special values of its parameters. The classical limit is used with physical theories that predict non-classical behavior. What are the laws of classical physics? It’s based […]

Is a 5K in 30 minutes good? Factors such as age, sex, and fitness level can influence your 5K time. Many runners complete a 5K in 30 to 40 minutes, and many runners are satisfied with their time if it’s around this benchmark. The average walker finishes a 5K in 45 to 60 minutes. How […]
