In the sciences and social sciences, they often publish research results. Substantive news articles are reliable sources of information on events and issues of public concern. How do you know if […]

How does viscosity affect drag? Drag force arises when an object moves through a fluid or, equivalently, when fluid flows past an object. In general, the drag force grows larger with increased flow velocity, but viscosity is a complex phenomenon that cannot be reduced to the simple relationship “drag force is proportional to velocity”. What […]

How do you describe chemical engineering? Chemical engineering is the branch of engineering that deals with chemical production and the manufacture of products through chemical processes. This includes designing equipment, systems and processes for refining raw materials and for mixing, compounding and processing chemicals to make valuable products. What problems do chemical engineers solve? Chemical […]

What is the formula for curvature? The radius of curvature of a curve at a point M(x,y) is called the inverse of the curvature K of the curve at this point: R=1K. Hence for plane curves given by the explicit equation y=f(x), the radius of curvature at a point M(x,y) is given by the following […]

Which utility program reads an assembly language source file and produces an object file? Assembler What is object file in assembly language? An object file is a computer file containing object code, that is, machine code output of an assembler or compiler. The object code is usually relocatable, and not usually directly executable. There are […]

How do you put PCA on a dataset? To get the dataset used in the implementation, click here. Import the dataset and distributing the dataset into X and y components for data analysis. Doing the pre-processing part on training and testing set such as fitting the Standard scale. Applying the PCA function into training and […]

How do you calculate the efficiency of an electric motor? To calculate a motor’s efficiency, you must measure its mechanical output power and divide it by the electrical input power. Measuring mechanical output power is fairly easy: You can use a torque meter to find the mechanical power based on the motor’s speed and load. […]

What is structural personal protective clothing designed to do? Figure 6.3 NFPA® 1971 regulates the clothing components that comply with the standard. Structural personal protective clothing is designed to cover all portions of your skin when you are reaching, bending, or moving. It is also designed to prevent heat transfer from the fire to your […]

Does the height depends on the distance between the person and the mirror? You will see that you only need a mirror length of about 1/2 your height. This is due to the principle of reflection, which states that the angle of incidence equals the angle of reflection. A light ray from your foot strikes […]
