What is the Cartesian equation? A Cartesian equation is an equation in terms of x and y only. Hence the Cartesian equation for the parametric equation x = t − 2, y = t2 is y = (x + 2)2. What is the normal vector of a plane? The normal vector, often simply called the […]

Is Xfinity 2.4 GHz or 5GHz? xFi Gateways are ‘dual band,’ meaning that they broadcast two separate radio bands for their WiFi network – a 2.4 GHz band and a 5 GHz band. Historically, you were encouraged to use a different WiFi name and password for each band. Should I name my 2.4 and 5GHz […]

What is a titration and what is it used to measure? A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Knowing the volume of titrant added allows the determination of the concentration of the unknown. Often, an indicator is used to usually signal […]

Why is red light not good for plants? Many plants grown under only red light, such as plants grown indoors under only red LEDs, have a stretched, elongated appearance; the leaves are thin and large and plants become tall. However, when a relatively small amount of blue light is added to red light, extension growth […]

Does elevation affect climate? And yes, elevation can affect climate. When you go high up, you will notice that the temperature feels much colder. There is also a shortage of oxygen as you go higher too. Factors like topography, winds, proximity, and human influences can affect climate also. Does air quality improve with elevation? Air […]

Is coffee an acid or base or neutral? Most coffee varieties are acidic, with an average pH value of 4.85 to 5.10 ( 2 ). Among the countless compounds in this beverage, the brewing process releases nine major acids that contribute to its unique flavor profile. Is Pepsi acid or base? Pepsi pH Level Pepsi […]

What is a sensitization? Sensitization is a non-associative learning process in which repeated administration of a stimulus results in the progressive amplification of a response. Sensitization often is characterized by an enhancement of response to a whole class of stimuli in addition to the one that is repeated. What type of organism is Aplysia? Aplysia […]

Is a car accelerating when turning? Acceleration is a vector quantity. So, we know that no matter what else might be going on, a turning car is accelerating – even if its speed is constant – since it is changing direction. Newton’s Second Law says that accelerations are caused by forces, so there must be […]

Is Delta G 0 for a reversible reaction? But for a reversible process delta G is always zero. This is not true; ΔG is always zero for a reversible process if it is carried out at constant temperature and pressure and the only kind of work involved is the p−V work. Which factor must be […]

What is the first step in attempting to free your vessel? 1 Answer. If you run aground in an outboard boat and you are not taking on water, the first step in attempting to free your vessel is to stop the boat’s engine, try to lift the out drive and shift the weight away from […]
