What happens to Wavefunctions as n increases? Note that as n increased, the energy of the wavefunction increases (Equation 3.5. 12) and both the number of nodes and antinodes increase and the frequency of oscillation of the wavefunction increases. When the particle strikes the wall of the well it bounces off completely true or false? […]

What is the resistor value? Resistors. A resistor is a device that opposes the flow of electrical current. The bigger the value of a resistor the more it opposes the current flow. The value of a resistor is given in ohms and is often referred to as its ‘resistance’. What will happen if DC power […]

How do we measure distance? Step 1: Add the first point On your Android phone or tablet, open the Google Maps app . Touch and hold anywhere on the map. You’ll see a red pin appear. At the bottom, tap the name of the place. On the place’s page, scroll down and choose Measure distance. […]

Which of these conditions will cause a rock to melt? The three factors that affect whether rock melts include temperature, pressure, and the presence of fluids in the rock. Rock melts when the temperature of the rock increases to above the melting point of minerals in the rock. Rock melts when excess pressure is removed […]

Which is the most common type of fingerprint pattern? Loop Does each finger have a different fingerprint? Yes, it is common to have different patterns on the fingers of one hand. The reason is because each finger develops individually. During fetal development, factors across the surface of each finger determine how the ridges will align. […]

What are the negatives of biofuels? Disadvantages of Biofuels High Cost of Production. Even with all the benefits associated with biofuels, they are quite expensive to produce in the current market. Monoculture. Use of Fertilizers. Shortage of Food. Industrial Pollution. Water Use. Future Rise in Price. Changes in Land Use. What are advantages and disadvantages […]

Is it safe to use a microwave that has peeling paint inside? If the coating is actively flaking or paint is peeling anywhere inside the oven cavity (including under the turntable) discontinue the use of the microwave and replace it. The microwave is not repairable. The inadvertent ingestion of small amounts of peeling coating does […]

How much pollution does energy produce? It’s a significant body of data given that power generation accounts for about a quarter of global carbon dioxide emissions at 10 billion tonnes per year. Over a quarter of that comes from the 8000 power plants in the United States, making its energy sector the biggest carbon emitter […]

What is Hertz formula? We denote frequency by Frequency is measured in Hertz = Hz = 1/seconds. If a wave with a wavelength of 2 meters is going by at a speed of 6 meters/second, then 3 complete waves go by in 1 second. That is, the frequency is 6/2 = 3 waves/second, or 3 […]
