What is polyatomic ion give example? Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit. What is the […]
What other quantity is your slope equal to?
What other quantity is your slope equal to? The slope is representing the change in v over the change in time. By definition, this is the acceleration. Also more than just a gimmick, it’s geometry’s way of showing us how variables not only relate to one another, but how they can represent the rate of […]
What is the importance of being precise and accurate?
What is the importance of being precise and accurate? When taking scientific measurements, it is important to be both accurate and precise. Accuracy represents how close a measurement comes to its true value. This is important because bad equipment, poor data processing or human error can lead to inaccurate results that are not very close […]
Does siliceous ooze dissolve?
Does siliceous ooze dissolve? Siliceous oozes bracket the carbonate belt and blend with pelagic clays farther north and south. Because siliceous skeletons dissolve so quickly in seawater, only the more robust skeletal remains are found in the siliceous oozes. What is it called when siliceous ooze Lithifies? When thick deposits of diatomic rich ooze accumulates […]
What are the 4 types of friendships?
What are the 4 types of friendships? Friendship is categorized into four types: acquaintance, friend, close friend and best friend. What are five characteristics of a good friend? The 13 Essential Friendship Traits I am trustworthy. I am honest with others. I am generally very dependable. I am loyal to the people I care about. […]
Why do we use thin gold foil?
Why do we use thin gold foil? For the scattering experiment, Rutherford wanted a metal sheet which could be as thin as possible. Gold is the most malleable of all known metals. It can easily be converted into very thin sheets. Hence, Rutherford selected a gold foil for his alpha-ray scattering experiment. What was most […]
How can longshore drift be stopped?
How can longshore drift be stopped? Groynes control beach material and prevent undermining of the promenade seawall. Groynes interrupt wave action and protect the beach from being washed away by longshore drift. Longshore drift is the wave action that slowly erodes the beach. Is longshore drift erosion or deposition? The material is transported through suspension, […]
How is flux generated?
How is flux generated? When a coil of wire is moved through a magnetic field a voltage is generated which depends on the magnetic flux through the area of the coil. Electric motors and generators apply Faraday’s law to coils which rotate in a magnetic field as depicted in Figure 3. In this example the […]
Is it possible to increase the temperature of a gas without giving it heat?
Is it possible to increase the temperature of a gas without giving it heat? Yes, during adiabatic compression the temperature of a gas increases while no heat is given to it. In compression work is done on the gas i.e. , work done is negative. Hence, internal energy of the gas increases due to which […]
What forms when water does not soak immediately underground?
What forms when water does not soak immediately underground? Water that soaks into the soil can also continue to percolate down through the soil profile below the water table into groundwater reservoirs, called aquifers. Water that doesn’t soak into the soil collects and moves across the surface as runoff, eventually flowing into streams and rivers […]
