Why is red a danger color? Why are the danger signals red in color? Ans. As the red light has the highest wavelength among all the colours, so it is scattered the least. Due to which most of the light gets reflected back and can travel longer distances through rain, fog, dust etc. to reach […]
Which best describes the electromagnetic force?
Which best describes the electromagnetic force? Electromagnetic force is the force which causes electric and magnetic effect such as repulsion between like charges or between two like poles of a magnet. This forces is long ranged and stronger with infinite range. It can be attractive or repulsive. What is the force which is not electromagnetic […]
What produces the most CO2?
What produces the most CO2? The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks. Which greenhouse gas contributes most to global warming? carbon dioxide […]
Does viscosity depend on speed?
Does viscosity depend on speed? Foams such as mixtures of liquids and gas and emulsions can exhibit higher apparent viscosity than either individual phase on its own. A change in viscosity based on the speed or force used, it may increase or decrease. Other than temperature, viscosity of the same fluid may vary with sheer […]
What are the examples of convex mirror?
What are the examples of convex mirror? Concave mirror v/s convex mirror – result Concave mirror Convex Mirror The examples of concave mirrors are the mirrors used in automobile head lights, reflecting telescopes, torch lights, etc. The examples of convex mirrors are the mirrors used as rear side mirrors of vehicles, optical instruments, calling bell, […]
Why does light take shortest path?
Why does light take shortest path? Light does travel on the path which would take the shortest time to travel between two points. This nature of light best explains the refraction of light when traveling across two mediums of different refractive index. Light does travel on the path which would take the shortest time to […]
Why is relative frequency important?
Why is relative frequency important? Relative frequency histograms are important because the heights can be interpreted as probabilities. These probability histograms provide a graphical display of a probability distribution, which can be used to determine the likelihood of certain results to occur within a given population. What is relative class frequency? In a relative frequency […]

How do we determine the conditions that existed in the early universe quizlet?
How do we determine the conditions that existed in the early universe quizlet? How do we determine the conditions that existed in the very early universe? We work backward from current conditions to calculate what temperatures and densities must have been when the observable universe was much smaller in size. Why can’t Current theories describe […]
What are the similarities and differences between digital and analog data?
What are the similarities and differences between digital and analog data? Digital data is stored in form of bits. Analog data is stored in form of waveform signals. Digital system needs low power as compare to its analog counterpart. Analog systems consume more power than digital systems. Is digital signal immune to noise? As a […]
