How does the kinetic energy of a moving body depends on its 1 speed and 2 mass? Hence, kinetic energy is directly proportional to mass of the body and directly proportional to the square of the speed of the body. How does the kinetic energy of moving body depends on its speed? (i) Kinetic energy […]
What is Gaussian surface and its importance?
What is Gaussian surface and its importance? Gaussian surface is a closed surface in three dimensional space through which the flux of a vector field is calculated; usually the gravitational field, the electric field, or magnetic field. The concept of Gaussian surface helps in evaluatig the electric field intensity due to symmetric charge distribution. What […]
Where are land breezes the strongest?
Where are land breezes the strongest? Land breezes are strongest along the immediate coastline but weaken considerably further inland. Land-breeze circulations can occur at any time of year, but are most common during the fall and winter seasons when water temperatures are still fairly warm and nights are cool. What breeze blows from land to […]
What is the best F ratio for astrophotography?
What is the best F ratio for astrophotography? Fast f/4 to f/5 focal ratios are generally best for lower power wide field observing and deep space photography. Slow f/11 to f/15 focal ratios are usually better suited to higher power lunar, planetary, and binary star observing and high power photography. Medium f/6 to f/10 focal […]
Do waves require medium?
Do waves require medium? Sound and water waves are mechanical waves; meaning, they require a medium to travel through. The medium may be a solid, a liquid, or a gas, and the speed of the wave depends on the material properties of the medium through which it is traveling. Why does electromagnetic wave does not […]
Which component of magma is the highest and the lowest in value?
Which component of magma is the highest and the lowest in value? Felsic magma has the highest silica content of all magma types, between 65-70%. As a result, felsic magma also has the highest gas content and viscosity, and lowest mean temperatures, between 650o and 800o Celsius (1202o and 1472o Fahrenheit). Could a mountain turn […]
What are the two types of reflection class 8?
What are the two types of reflection class 8? 4.1 Regular Reflection. 4.2 Diffuse reflection or irregular reflection. What is the best reflective model? Gibbs’ Reflective Cycle. One of the most famous cyclical models of reflection leading you through six stages exploring an experience: description, feelings, evaluation, analysis, conclusion and action plan. What are the […]
Why is Aluminium good for aircraft?
Why is Aluminium good for aircraft? Aluminum is ideal for aircraft manufacture because it’s lightweight and strong. Aluminum is roughly a third the weight of steel, allowing an aircraft to carry more weight and or become more fuel efficient. Furthermore, aluminum’s high resistance to corrosion ensures the safety of the aircraft and its passengers. Why […]
What are reactive metals used for?
What are reactive metals used for? Reactive metals, such as magnesium, are widely used in rust prevention and are known as sacrificial anodes. Iron will rust unless protected in some way. Reactive metals, when attached to less reactive metals, have the ability to prevent the less reactive metal from rusting. What are the five key […]
