What are 4 facts about the troposphere? Fact Sheet The troposphere contains 75% of the atmosphere’s total mass. In either space or time the troposphere is not constant. Weather occurs in the troposphere. The troposphere is 10 miles from the equator. The troposphere is 5-7 miles above the poles. Does not contain ozone. What happens […]

How is convection used in everyday life? radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea – The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting – […]

Is the basilar membrane connected to the ear drum? The basilar membrane is a stiff structural element within the cochlea of the inner ear which separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani….Basilar membrane. Basilar membrane. MeSH D001489 Anatomical terminology What would happen if […]

Is a 1000ml 1 liter? Remember that 1 L = 1000 mL. How much volume is in a liter? A litre is a cubic decimetre, which is the volume of a cube 10 centimetres × 10 centimetres × 10 centimetres (1 L ≡ 1 dm3 ≡ 1000 cm3). Hence 1 L ≡ 0.001 m3 ≡ […]

What is RHF method? In computational physics and chemistry, the Hartree–Fock (HF) method is a method of approximation for the determination of the wave function and the energy of a quantum many-body system in a stationary state. A solution of these equations yields the Hartree–Fock wave function and energy of the system. What is the […]

What is the takeoff velocity? A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings. Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 […]

How do you show a uniform magnetic field? Hint: A uniform magnetic field is one that has the same strength and direction at all points. It is represented by a set of parallel lines that are equally spaced apart. The direction of the magnetic field lines points in the same direction as a north-south pole […]

What is the saying for every action there is a reaction? Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object […]

Is 18 carat gold good for daily use? It is not a good idea to choose 18K gold for pieces that you will wear every day, especially rings or bracelets, which are more likely to get hit or scratched. In such cases, 14K or 10K gold may be a better choice as it will not […]

What was the real reason for the Civil War? What led to the outbreak of the bloodiest conflict in the history of North America? A common explanation is that the Civil War was fought over the moral issue of slavery. In fact, it was the economics of slavery and political control of that system that […]
