Why is it difficult for a high speed car to negotiate an unbanked turn? (a) A huge force is pushing the car outward. (b) The magnitude of the friction force might not be enough to provide the necessary radial acceleration. A car negotiating an unbanked road at high speed is actually accelerating as the direction […]
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 another name for the celestial coordinate system?
What is another name for the celestial coordinate system? equatorial coordinate system. Save This Word! The coordinate system in which a celestial object’s position on the celestial sphere is described in terms of its declination and right ascension, measured with respect to the celestial equator. What is the most common celestial coordinate system? equatorial coordinate […]
Can a tuning fork go out of tune?
Can the sign of the acceleration ever be positive for an object that is slowing down?
Can the sign of the acceleration ever be positive for an object that is slowing down? According to our general principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object also has a positive acceleration. Is it true that acceleration only takes place when speeding […]
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 is a disadvantage of hydrogen fuel cells?
What is a disadvantage of hydrogen fuel cells? There are disadvantages to using hydrogen-oxygen fuel cells in cars. These include: hydrogen is in the gas state at room temperature and pressure, so it is difficult to store in the car. fuel cells and electric motors are less durable than petrol engines and diesel engines, so […]
What are the main sources of error in enthalpy experiments?
What are the main sources of error in enthalpy experiments? Sources of error Likely sources of experimental error in this experiment include improper mixing, the placement of the thermometer bulb onto slowly dissolving solids, incorrect reading of the thermometer, not enough thermometer readings, and spillages. The most probable sources of error are the first two. […]
How do you poop after hip surgery?
How do you poop after hip surgery? After surgery, you should also plan to take a stool softener, such as docusate (Colace). A fiber laxative, such as psyllium (Metamucil), may also be helpful. Purchase a laxative or stool softener before your surgery so that you have it available when you return home. Can you ever […]
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 […]
