How do you call a base class function from a derived class?
How do you call a base class function from a derived class? To modify the way a function defined in a base class works in the derived class, simply redefine the function in the derived class. Note that when you redefine a function in the derived class, the derived function does not inherit the access […]
How do you find the normal depth of a trapezoidal channel?
How do you find the normal depth of a trapezoidal channel? Answer: normal depth = 1.02 m. (b) Geometry: trapezoidal cross-section with base width b, surface width �� + 2 × (2ℎ) and two sloping side lengths √ℎ2 + (2ℎ)2 = ℎ√5. How do you find the slope of a trapezoid? Trapezoidal Cross Section The […]
How does the law of conservation of mass apply to the real world?
How does the law of conservation of mass apply to the real world? The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when […]

How is Burger vector calculated?
How is Burger vector calculated? For the determination of the Burgers vector you need to insert the type of an expected dislocation. Then go around the dislocation core (line) adding the same amount of steps (vector). The missing vector component is the shift caused by the dislocation. That’s the Burgers vector. Why does a dislocation […]
When a metal is heated its density decreases?
When a metal is heated its density decreases? Answer: When a metal is heated, its density decreases. There are two sources that give rise to this decrease of ρ: (1) the thermal expansion of the solid and (2) the formation of vacancies (Section 4.2). Consider a specimen of gold at room temperature (20°C) that has […]
How do you determine your foundation size?

What is the difference between plan and elevation?
What is the difference between plan and elevation? In basic terms, a plan is a birds-eye view of a space. When drawing a floor plan, the roof would be removed so the interior space can be seen. An elevation is a view from the side of an object, when drawing interior elevations, this would represent […]
