Why should you not use a credit card? Using credit cards and not paying them off monthly can be detrimental to your credit. The major downsides of using credit when you don’t have the cash to pay it off later—besides the high-cost interest—includes hurting your credit, straining family and friend relationships, and ultimately bankruptcy. What […]

What is the difference between a conventional system and a heat pump? What’s the difference between a conventional system and a heat-pump unit? A heat pump can reverse its direction and transfer heat from the outside to heat indoor temperatures, whereas a conventional air conditioning system requires a separate furnace unit to produce and distribute […]

What is after Alpha? The Greek letters you are most likely to see for angles are α (alpha), β (beta), γ (gamma), δ (delta), and θ (theta). What is the name of μ? micro What is the omega wolf? An omega wolf can be either male or female and is the scapegoat, the lowest ranking […]

What is a respectable 400m time? 61s is a decent time for an amateur runner with little training. You can also do a whole lot better by training diligently. Freshmen in high school (varying from 400m specific to distance runners) can beat that time but… Who holds the 400m world record? Wayde van Niekerk Is […]

Why do canoes move backwards? To compensate for this the centre of mass of the canoe should move an equivalent distance in the backward direction so as to compensate for the movement of the centre of mass of the man and keep the centre of mass of the system at the same place. When the […]

How do you drop a raw egg without breaking it? Explanation: The right answer to the riddle is Concrete floor can not be cracked by an egg. The Concrete floor is too hard to be cracked by an egg, the egg will break. Why does an egg not crack when you squeeze it? The egg […]

How do you calculate the capacitance of an AC circuit? The relationship between this charging current and the rate at which the capacitors supply voltage changes can be defined mathematically as: i = C(dv/dt), where C is the capacitance value of the capacitor in farads and dv/dt is the rate of change of the supply […]

What is the role of water in noncyclic electron flow? What is the purpose of water in the noncyclic flow of electrons in photosynthesis? water splits, thus giving electrons to P680 and having 2 hydrogen ions and one oxygen atom. This all releases O2. What is the difference between noncyclic and cyclic electron flow? Non-cyclic […]

Is length qualitative or quantitative? Quantitative Information – Involves a measurable quantity—numbers are used. Some examples are length, mass, temperature, and time. Quantitative information is often called data, but can also be things other than numbers. Qualitative Information – Involves a descriptive judgment using concept words instead of numbers. Is malleability qualitative or quantitative? 14 […]

What is the effects of temperature? An increase in the temperature of a system favors the direction of the reaction that absorbs heat, the endothermic direction. Absorption of heat in this case is a relief of the stress provided by the temperature increase. For the Haber-Bosch process, an increase in temperature favors the reverse reaction. […]
