Why is red light not bright? For a given electrical power in, red LEDs look about twice as bright as blue. That is measured in lumens per watt. Red is used to preserve night vision because the rod cells used in dim light are less sensitive to red than blue. So red will be visible […]

Jupiter is a large planet, while the other outer planets are small. Which planets are called ice giants select two options? An […]
In what specific situations would you use a light microscope?
In what specific situations would you use a light microscope? A light microscope is used to view the details of the surface of a cell as it cannot be viewed in detail by the transmission microscope. b. A light microscope allows visualization of small living cells, which have been stained and cannot be viewed by […]
What type of bond is found between water molecules?
What type of bond is found between water molecules? hydrogen bonds What type of IMFA is carbon dioxide? London dispersion forces Is there a dipole in CO2? A molecule like CO2 may be composed of two dipoles, but it has no dipole moment. When molecules have an even charge distribution and no dipole moment, then […]
How do you know if two organisms are the same species?
How do you know if two organisms are the same species? Organisms belong to the same species if they can interbreed to produce fertile offspring. Species are separated by prezygotic and postzygotic barriers, preventing mating or producing fertile offspring. What are the six types of macroevolution? There Are Six Important Patterns of Macroevolution: Mass Extinctions. […]
What is the principle of viscosity?
What is the principle of viscosity? The principle of viscosity is stated here: When a layer of liquid is subjected to move upon a surface or another layer of the same liquid, the fluid particles tend to oppose such movement; this resisting force developed by a liquid is called viscosity. What is viscosity volcano? When […]
What is the formula of Circumcentre?
What is the formula of Circumcentre? Since D1= D2 = D3 . To find out the circumcenter we have to solve any two bisector equations and find out the intersection points. The slope of the bisector is the negative reciprocal of the given slope. The slope of the bisector is the negative reciprocal of the […]
What are two differences between heat and temperature?
What are two differences between heat and temperature? Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or […]
Is green light healthy?
Is green light healthy? Green light therapy, fibromyalgia, and other pain-related conditions. It’s not just migraine, but chronic pain conditions that may be helped by green light therapy. For example, green light was shown to have a positive effect on pain from fibromyalgia—a condition marked by widespread pain, sleep problems, and fatigue. Does green light […]
