Which brain structure allows us to pay attention to stimuli? In both cases, the prefrontal cortex — the control center for most cognitive functions — appears to take charge of the brain’s attention and control relevant parts of the visual cortex, which receives sensory input. What areas of the brain are involved in attention? The […]
Who put forth the wave theory of light?
Who put forth the wave theory of light? In his Traité de la Lumière (1690; “Treatise on Light”), the Dutch mathematician-astronomer Christiaan Huygens formulated the first detailed wave theory of light, in the context of which he was also able to derive the laws of reflection and refraction. How accurate is Elliott Wave? We are […]
What are conventional sources?
What are conventional sources? Conventional sources of energy are the natural energy resources which are present in a limited quantity and are being used for a long time. Some common examples of conventional sources of energy include coal, petroleum, natural gas and electricity. What is meant by non conventional? : not conventional : not conforming […]
Which is faster 5 meters per second?
Which is faster 5 meters per second? In other words, 5 meters per second is 0.485 times the speed of Usain Bolt, and the speed of Usain Bolt is 2.1 times that amount. How fast is 100km in mph? Kilometer/hour to Mile/hour Conversion Table Kilometer/hour [km/h] Mile/hour [mi/h] 20 km/h 12.4274238447 mi/h 50 km/h 31.0685596119 […]
How can you tell what time something falls?
What is the energy content per photon?
What is the energy content per photon? Photons are electrically neutral. Photons have no mass, but they have energy E = hf = hc/λ. Here h = 6.626*10-34 Js is a universal constant called Planck’s constant. The energy of each photon is inversely proportional to the wavelength of the associated EM wave. What is the […]
What is maximum voltage drop allowed?
What is maximum voltage drop allowed? The maximum conductor voltage-drop recommended for both the feeder and branch circuit is 5% of the voltage source (120V). The total conductor voltage drop (feeder and branch circuit) shouldn’t exceed 120V×0.05=6V. What is the effect of voltage drop? The effect of voltage drop on some key electrical equipment is […]
What is the specific heat capacity for water?
What is the specific heat capacity for water? 4,184 Joules How do you calculate calorimetry? A calorimeter is a device that is used to measure the quantity of heat transferred to or from an object. Coffee cup calorimeter is usually filled with water and used as a common calorimeter….The Formula for Calorimetry: Q_{sub} Heat Energy […]
How would you describe low tide?
How would you describe low tide? The tide at its lowest level at a particular time and place. The lowest tides reached under normal meteorological conditions (the spring tides ) take place when the Moon and Sun are directly aligned with respect to Earth. Low tides are less extreme when the Moon and Sun are […]
What happens when primary resistors are used to start a motor?
What happens when primary resistors are used to start a motor? Primary resistor starters provide closed transition starting. This means the motor is never disconnected from the line from the moment it’s first connected until the motor is operating at full line voltage. This feature may be important in wiring systems sensitive to voltage changes. […]
