Suppose that hotdogs are inferior good. True or false, explain. “If the income of the consumers is rising, hamburger prices are falling and the price of hotdog casing (the
synthetic skin around the hotdog) increase, we can conclude that the quantity of
hotdogs consumed will go down and the price change is indeterminate”. Use welllabeled demand and supply diagram(s) in your explanation.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

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?

Brief discuss how the presence of dislocations in crystal structures can be an advantage and a disadvantage to engineer and designers.
