What is the coefficient of viscosity of glycerin?
0776 N S/m2
What was the significance of Chandra Gupta 2's military victories?
The significance was that Chandra's wife Ufreti let him rule lower India for too long and he eventually grew old and couldn't fight the military's obligation
Forms of linear equations?
The slope-intercept form: y = mx + c or the general linear equation: ax + by = k The second can be extended to 3 (or more dimensions) simply by adding the appropriate coefficient(s) and variable(s), for example, ax + by + cz = k (hence the term generalised)
How to calculate Flow in a partially full pipe?
Use Mannings Equation: Q=(1.486/n)*(A)*(R)^(2/3)*S^(1/2) Q = Flow (CFS) n = Roughness Coefficient A = Cross sectional flow Area of Fluid (FT*FT) R = Hydraulic Radius (FT) S = Slope (FT/FT)
What is the shape of a cubic function?
If the coefficient of x^3 is negative then the shape is a bit like the letter "S" pushed over from the left and then both free ends stretched out for ever. Such a graph starts at the top left and goes down towards the bottom right with the gradient (slope) becoming steadily less steep. It can then move upwards for a short while before it continue its downward motion - only this time the gradient becomes steeper as you go along. Note that the upward bump may not be there (if there is a point of inflexion). If the coefficient of x^3 is positive then the graph is a mirror image.
