What is called work function? From Wikipedia, the free encyclopedia. In solid-state physics, the work function (sometimes spelled workfunction) is the minimum thermodynamic work (i.e., energy) needed to remove an electron from a solid to a point in the vacuum immediately outside the solid surface. What is a high work function? molecules is ionized by […]
What is the potential at point B?
Do they weigh you before hot air balloon ride?
Do they weigh you before hot air balloon ride? Every Balloon has a maximum level of weight it can carry. Before a flight, the pilot uses the passenger’s weight to decide how many people can go in each basket. While most of our local competitors will charge double for Passengers weighing more than 200 lbs. […]
How can you tell if you can see ultraviolet light?
How can you tell if you can see ultraviolet light? By definition, ultraviolet light is ‘beyond violet light’ and the visible spectrum that can be detected by the human eye. It cannot, therefore, be seen directly. Detectors that are sensitive to UV convert it into a form that we can see. Can humans see Violet? […]
What is the relationship between energy and frequency?
What is the relationship between energy and frequency? Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν. […]
What is the SI unit of viscosity?
What is the SI unit of viscosity? The SI unit for kinematic viscosity is square meters per second (m2/s). However, due to the viscosity values of most common fluids, square centimeters per second (cm2/s) is used more often. Note that 1 cm2/s is equivalent to 100 cSt. What is retardation write its formula? Deceleration also […]
What is the current solar cycle?
What is the current solar cycle? December 2019 marks the beginning of Solar Cycle 25, and the sun’s activity will once again ramp up until solar maximum, predicted for 2025. Image via NASA/ Solar Dynamics Observatory (SDO). They announced on December 7, 2020, their prediction that Solar Cycle 25 will be one of the strongest […]
What are three examples of parasitism?
What are three examples of parasitism? A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles. What are the three […]
What are 3 things that can generate electrical energy?
What are 3 things that can generate electrical energy? The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. How do we get our energy […]
