How do you calculate volume of water flow? The volume of a portion of the fluid in a pipe can be written as V = A d V=Ad V=AdV, equals, A, d, where A is the cross sectional area of the fluid and d is the width of that portion of fluid, see the diagram […]
What is called instantaneous speed?
What is called instantaneous speed? Definition: When the speed of an object is constantly changing, the instantaneous speed is the speed of an object at a particular moment (instant) in time. What is the difference between velocity and speed? The reason is simple. Speed is the time rate at which an object is moving along […]
How do you know if a vessel is thin walled?
What is an example of sustainable use?
What is an example of sustainable use? Renewable clean energy is probably the most obvious example of sustainability. Here are three examples. Solar energy: Once the sun’s electromagnetic radiation is captured, it produces electricity and heat. Wind Energy: Wind turbines convert the kinetic energy in the wind into mechanical power. Which is a sustainable practice? […]
What happens next depends on the mass of the star?
Why is Pluto white?
Why is Pluto white? Pluto is the only place other than Earth in our solar system that’s known to have white-peaked mountains, but these white caps aren’t made of snow. Instead, they’re made of methane frost. The mountains are made of water ice, as temperatures on this dwarf planet can drop as low as minus […]
What would happen if everyone was vegan?
What would happen if everyone was vegan? If we all went vegan, the world’s food-related emissions would drop by 70% by 2050 according to a recent report on food and climate in the journal Proceedings of National Academy of Sciences (PNAS). The study’s authors from Oxford University put the economic value of these emissions savings […]
What are the 3 types of photographs that need to be taken at a crime scene?
What are the 3 types of photographs that need to be taken at a crime scene? To accomplish this, all crime scene photography consists of three basic types of photographs: overall, mid-range, and close-up. What are the three methods of documenting a crime scene? The three most common methods of recording a crime scene are: […]
How many moles is 1 MgCl2 FM?
Why does the viscosity of liquids decrease with temperature?
Why does the viscosity of liquids decrease with temperature? The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced. How does viscosity of liquids vary with temperature? The viscosity of liquids decreases rapidly with an […]
