What is the formula for capacitance of a capacitor? The generalised equation for the capacitance of a parallel plate capacitor is given as: C = ε(A/d) where ε represents the absolute permittivity of the dielectric material being used. How can you increase the capacitance of a parallel plate capacitor? The capacitance of a set of […]
How are elements heavier than beryllium formed?
How are elements heavier than beryllium formed? Elements heavier than beryllium are formed through stellar nucleosynthesis. Stellar nucleosynthesis is the process by which elements are formed within stars. The abundances of these elements change as the stars evolve. What is the heavy element? A heavy element is an element with an atomic number greater than […]
Will cats come down from trees on their own?
Will cats come down from trees on their own? Cats’ claws are shaped like fish hooks, and trees are nature’s escape routes for them. They will often climb until they feel safe, then stop and realize they’re stuck. The only safe way for them to get down unaided is to go down backward, which, unsurprisingly, […]
What makes a roller coaster go faster?
How many hours of sun does a north-facing garden get?
How many hours of sun does a north-facing garden get? You’ll get quite a bit at the height of summer, I should think about 7 hrs a day ime, central England latitude — more if you’re further north. Obviously at the ends of the day (morning, early evening. Good aspect for a conservatory (won’t get […]
Why is the corona hotter?
Why is the corona hotter? Nanojets are thought to be initiated by a process called ‘magnetic reconnection’, where twisted magnetic fields explosively realign. One such reconnection can set off another, resulting in an avalanche of nanojets in the Sun’s corona, which is then thought to generate enough energy to heat the corona. What triggers lightning? […]
What are 5 ways rocks can be broken down?
What are 5 ways rocks can be broken down? Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits […]
How do you describe an irregular galaxy?
How do you describe an irregular galaxy? An irregular galaxy is the catchall name given to any galaxy that does not neatly fit into one of the categories of the Hubble classification scheme. They have no defined shape nor structure and may have formed from collisions, close encounters with other galaxies or violent internal activity. […]
What is the volume of a 6cm Cube?
What is the relationship between heat work and internal energy?
What is the relationship between heat work and internal energy? The relationship between the internal energy of a system and its heat and work exchange with the surroundings is: E = q + w (The form of work will be restricted to gaseous, PV-type for this discussion.) Interestingly, both q and w are not state […]
