Hart of Michigan and Representative Emanuel Celler of New York—the law overhauled America’s immigration system during a period of deep global instability. Why […]
What is real and apparent Expansivity?
What is real and apparent Expansivity? The real (or absolute) expansivity of a liquid is the fraction of its volume by which it expands per kelvin rise in temperature. The apparent expansivity of a liquid is the fraction of its volume by which the liquid appears to expand per kelvin rise in temperature when heated […]
What causes an element to be reactive?
What causes an element to be reactive? The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Alkali metals are highly reactive because they readily lose the single electron in their outermost shell. What are some examples of reactivity? Reactivity […]

Why is a sit up a second class lever? Second-Class Levers In a second-class lever, the resistance lies between the fulcrum and the force, as in a wheelbarrow. Exercises that require plantarflexing the ankle, such as seated or standing calf raises, employ a second-class lever. What’s an example of a second class lever? In a […]
What is standard takeoff minimums?
What is standard takeoff minimums? As a quick reminder, standard takeoff minimums for one and two engine airplanes is 1-mile visibility and a 1/2 mile visibility for 3-4 engine airplanes. How do you find alternate minimums? To view the non-standard IFR alternate minimums information, you will need to go to the Airports page > search […]
Does frequency change power?
Does frequency change power? Frequency of the system will vary as load and generation change. Increasing the mechanical input power to a synchronous generator will not greatly affect the system frequency but will produce more electric power from that unit. Can I use a 60 Hz device in a 50 Hz power frequency? Electrical machines […]
What comes through nuclear pores?
What comes through nuclear pores? Each nuclear pore is a large complex of proteins that allows small molecules and ions to freely pass, or diffuse, into or out of the nucleus. Similarly, RNA transcribed in the nucleus and proteins that are destined to enter the cytoplasm have nuclear export sequences that tag them for release […]
What are 6 different tests that are used to identify minerals?
What are 6 different tests that are used to identify minerals? Geologists use the following tests to distinguish minerals and the rocks they make: hardness, color, streak, luster, cleavage and chemical reaction. What are the two main types of mineral classification? Minerals are classified based on their crystal form and chemistry. Minerals are divided into […]
