Are lower taxes better for the economy? Tax Cuts and the Economy Further, reduced tax rates could boost saving and investment, which would increase the productive capacity of the economy. In other words, economic growth is largely unaffected by how much tax the wealthy pay. Growth is more likely to spur if lower income earners […]

Can a vector have a component equal to zero? Yes, a vector can have a component equal to zero and still have a nonzero magnitude. What is Cartesian form of vector? We know that = xi + yj. The vector , being the sum of the vectors and , is therefore. This formula, which expresses […]

Is a 20 volt drill more powerful than a 12 volt drill? 1. Power. The main difference between 12v, 18v, and 20v tools is their power; the higher the voltage of the tool means the more influential the tool is, so here the voltage is 12, 18, and 20 volts, indicating the 12v tool has […]

What is the rarest color of zircon? Green Which Zircon is best? E.g. – A person weighing 60 kgs can wear a 6-carat Zircon gemstone. A highly transparent, colorless natural Zircon is preferred for astrological purposes. Silver or platinum is considered, the best. Alternatively, panchdhaatu, gold or white gold can also be used. Who should […]

Are 3 or 5 blade fans better? When it comes to design and aesthetic look, the 3 bladed ceiling fan is more pleasing than the 5 bladed. Generally, the more blades the ceiling fan has, the quieter it is and circulates less air. Ceiling fan with more blades can increase the drag on the motor […]

Which planet has the greatest erosion? Mars What causes erosion on the moon? The solar wind and micro-meteorite impacts appear to be the main drivers of erosion on the Moon today as well as the big temperature change between day and night which weakens and breaks up rock. Why does the moon almost have no […]

What is the formula for dynamic resistance? The diode has the following characteristics: threshold voltage V0 = 0.6 V, forward dynamic resistance Rd = 0 and infinite reverse resistance. How do you calculate dynamic resistance on a graph? The slope of the graph between current and voltage in a p-n junction diode, under both forward […]

When electrons are transferred between two atoms a covalent bond is formed? Covalent bonds and molecules A covalent bond is formed when two atoms share electron pairs. In a covalent bond, the stability of the bond comes from the shared electrostatic attraction between the two positively charged atomic nuclei and the shared, negatively charged electrons […]

Can you test continuity on a live circuit? You can measure the voltage and the current of a live circuit and use those figures to calculate the resistance (Ohm’s Law), but you can’t actually measure the resistance of a live circuit. For a number of reasons, you need to turn the power off and measure […]
