Introduction. The concept of fugacity was defined by G. N. … Lewis defined a ratio of fugacities to yield thermodynamic activities, and fugacity is the pressure if the gases both satisfy the ideal gas law and if the standard-state fugacity is defined for a total pressure of 1 bar (105Read More →
The secant is the reciprocal of the cosine. The cotangent is the reciprocal of the tangent. Is sec just cos flipped? Secant is the reciprocal of cosine. Its abbreviation is sec. To determine sec, just flip cos over. Cotangent is the reciprocal of tangent. What is the inverse of sec?Read More →
are called Consecutive Interior Angles. d and f are Consecutive Interior Angles. … When the two lines are parallel, any pair of Consecutive Interior Angles add to 180 degrees. Are Consecutive angles supplementary? Any pair of consecutive angles are supplementary . All angles are right angles. Opposite angles are congruent.Read More →
Var(X) = λ2 + λ – (λ)2 = λ. This shows that the parameter λ is not only the mean of the Poisson distribution but is also its variance. What is the value of variance in a Poisson distribution? Mean and Variance of Poisson Distribution. If μ is the averageRead More →
A rhombus has all sides equal, while a rectangle has all angles equal. A rhombus has opposite angles equal, while a rectangle has opposite sides equal. … The diagonals of a rhombus intersect at equal angles, while the diagonals of a rectangle are equal in length. Does a rhombus haveRead More →
Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom. Why is the numberRead More →
Therefore 360º = 2 PI radians. Therefore 180º = PI radians. So one radian = 180/ PI degrees and one degree = PI /180 radians. Therefore to convert a certain number of degrees in to radians, multiply the number of degrees by PI /180 (for example, 90º = 90 ×Read More →
To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens. HowRead More →
She highlighted that with an estimated 7.2 billion humans on the planet today, the combined weight would total to about 332bn kg. If we can imagine that there are 10,000 trillion ants in the world, all weighing an average of 4 mg, their total weight would equal around 40bn kg.Read More →
The four interior angles in any rhombus must have a sum of degrees. The opposite interior angles must be equivalent, and the adjacent angles have a sum of degrees. Does a rhombus have 4 right angles? A rhombus is defined as a parallelogram with four equal sides. Is a rhombusRead More →
