What happens if a hydrogen car catches fire? The vehicles are designed with a thermal pressure relief device (TPRD) on the tank that would discharge if the car was engulfed in a fire. If a fuel leak were to occur, the hydrogen would disperse upward rapidly, and if the TPRD were activated, the tank would […]
What is angular momentum of a particle?
What is angular momentum of a particle? The angular momentum of a rigid object is defined as the product of the moment of inertia and the angular velocity. It is analogous to linear momentum and is subject to the fundamental constraints of the conservation of angular momentum principle if there is no external torque on […]
What does it mean to find the inverse of a function?
What is the term for the angle at which light undergoes total internal reflection?
What is the term for the angle at which light undergoes total internal reflection? This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur. For any angle of incidence greater than the critical angle, light will undergo total internal reflection. Which of […]
How does the 1st and 2nd law of thermodynamics apply to biological systems?
How does the 1st and 2nd law of thermodynamics apply to biological systems? Two fundamental concepts govern energy as it relates to living organisms: the First Law of Thermodynamics states that total energy in a closed system is neither lost nor gained — it is only transformed. The Second Law of Thermodynamics states that entropy […]
Why does glass amplify sound?
Why does glass amplify sound? It happens because glass resonates at frequencies we can hear. The resonant frequency of the glass changes with its thickness. When energy at that frequency meets the glass, it causes the glass to vibrate like a drum head. How do you physically amplify sound? Untitled Document. Sounds can be made […]
What is difference between PCT and DCT?
What is difference between PCT and DCT? PCT occurs after the Bowman’s capsule while DCT occurs after the loop of Henle. PCT is mainly involved in the reabsorption whereas secretion occurs in the DCT. The main difference between PCT and DCT is that PCT is the function of each part in the nephron. Which is […]
Is ear popping a good sign?
Is ear popping a good sign? Having clogged ears can be uncomfortable and may muffle your hearing. When this happens, popping your ears may help. Popping your ears is generally safe. It usually requires little more than moving your mouth muscles. Is ear popping a sign of infection? When doctors refer to an ear infection, […]
