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 […]
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 […]
Does radiation travel at the speed of light?
Does radiation travel at the speed of light? Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. How long would it […]
What is the 6 biggest planet?
How does a motor operate?
How does a motor operate? Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current. How do I select a motor for an application? 5 steps to choose the […]
What is the rejection region for the hypothesis test?
What is the rejection region for the hypothesis test? The rejection region is the interval, measured in the sampling distribution of the statistic under study, that leads to rejection of the null hypothesis H 0 in a hypothesis test. What is a critical value in statistics? A critical value is a line on a graph […]
