How do you simplify Bodmas?
How do you simplify Bodmas? These letters stand for vinculum, bracket, of, division, multiplication, addition and subtraction respectively. The sums on simplification must be solved in that order i.e., first solve vinculum followed by bracket and so on until the sum is solved. In simplifying an expression first of all bar must be removed. What […]

How long did the Tacoma Narrows Bridge last? After 29 months of construction, a new and much safer Tacoma Narrows Bridge opened on Oct. 14, […]
What is called electric resistance?
What is called electric resistance? In electronics and electromagnetism, the electrical resistance of an object is a measure of its opposition to the flow of electric current. The reciprocal quantity is electrical conductance, and is the ease with which an electric current passes. Does 240V need a neutral? A 240V load needs two “ungrounded conductors”, […]
What does fully ionized mean?
What does fully ionized mean? When referred to an atom, “fully ionized” means that there are no bound electrons left, resulting in a bare nucleus. Regular stars largely contain hydrogen and helium that are fully ionized into protons (H+) and alpha-particles (He2+). Which element would have the highest ionization energy? helium What is Fluorines ionization […]
What clues did you use to put the continents together?
What clues did you use to put the continents together? Wegner’s Evidence for Continental Drift Evidence from fossilized organisms and mountain chains can be used to reconstruct the positions of today’s continents and landmasses to form the supercontinent Pangea.

What will happen to the pressure of a contained gas if its temperature is lowered?
What will happen to the pressure of a contained gas if its temperature is lowered? How does a decrease in temperature affect the pressure of a contained gas? The pressure decreases because the kinetic energy decreases with the temperature and slower moving particles impact the walls of a contain with less energy. Which three factors […]
