When a fluid flows over an object, the "pressure" or "form" drag:

(a) depends only on the reynolds number.
(b) depends on the pressures acting normal to the flow direction.
(c) depends on the orientation with respect to the flow direction but not on the velocity.
(d) depends on the orientation with respect to the flow direction and also on the velocity.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
