Can a tuning fork go out of tune? No, you can’t whack a fork too hard and make it ring out of tune! It will have been like that from the factory. You can re-tune a fork that is flat by grinding of some material from the ends of both forks. grind it a tiny […]
Is angular momentum conserved rolling without slipping?
Is angular momentum conserved rolling without slipping? In rolling motion without slipping, a static friction force is present between the rolling object and the surface. A rigid rotating body has angular momentum directed along the axis of rotation. 11.4: Conservation of Angular Momentum. In the absence of external torques, a system’s total angular momentum is […]
Why is the skull divided into two parts?
Why is the skull divided into two parts? The skull is a bone structure that forms the head in vertebrates. It supports the structures of the face and provides a protective cavity for the brain. The skull is composed of two parts: the cranium and the mandible…. Skull TA98 A02.1.00.001 TA2 406 Anatomical terminology What […]
What is a piece of cosmic debris on Earth called?
What is a piece of cosmic debris on Earth called? It also contains countless asteroids and comets – the debris of the cosmic construction site that created the planets and their moons. The majority of Solar System asteroids populate the main asteroid belt, lying between the orbit of Mars and Jupiter. How much space debris […]
What causes sodium voltage-gated channels to open?
What causes sodium voltage-gated channels to open? When a stimulus reaches the threshold at the axon hillock, an action potential is generated. An action potential relies on many protein channels. All the voltage-gated Sodium channels open when the membrane potential reaches around -55 mV and there’s a large influx of Sodium, causing a sharp rise […]
What does the bubbling indicate?
What does the bubbling indicate? When substances are put in the same container like, CaCO3 and HCl . A reaction occurs and bubbles escape the container (effervescence). These bubbles are actually gas fumes, and this shows that a new gaseous product is formed. Here, bubbling indicates our chemical reaction. What are the bubbles that you […]
What cycle does a refrigerator work on?
What cycle does a refrigerator work on? Air cycle refrigeration works on Reversed Carnot cycle and Bell Coleman cycle. Air is compressed and then heat removed, this air is then expanded to a lower temperature than before it was compressed. . Where is refrigeration used? Refrigeration has many applications, including household refrigerators, industrial freezers, cryogenics, […]
What are the types of digest?
What are the types of digest? Digestion is often broken down into two types: Mechanical digestion — food is physically broken into smaller parts. For instance, by chewing. Chemical digestion — food is broken down by acids and enzymes into its basic units. What are the six steps of the digestive system? The processes of […]
What is energy stored in an object called?
What is energy stored in an object called? Energy stored in an object due to its position is Potential Energy. · Energy that a moving object has due to its motion is Kinetic Energy. Kinetic Energy: Is energy of motion. What type of energy is related to height? Gravitational potential energy increases as weight and […]
Why do mid-latitude cyclones finally die out?
Why do mid-latitude cyclones finally die out? All mid-latitude cyclones eventually weaken and dissipate. This can happen for a combination of the following reasons: loss of access to warm air, loss of access to moisture, occlusion of cooler/drier air around the low. Generally, the cold front moves faster than the warm front. How long do […]
