Assume we have a 1D print pattern with a resolution (i. e., spatial sampling frequency) of 120 dots per cm, which equals approximately 300 dots per inch (dpi) and a total signal length of N= 2800 samples. Calculate the
i. Sampling interval [2]
ii. Physical signal length [1]
iii. The fundamental frequency of this signal (again implicitly assumed to be periodic) [1]
iv. Maximum frequency that can be represented by this signal without aliasing [2]
v. A 1D optical scanner for sampling film transparencies is supposed to resolve image structures
with a precision of 3,000dpi. What spatial distance (in mm) between samples is required such
that no aliasing occurs?

The “death throes” of stars are amongst the most complex phenomena in all of astronomy, and the “corpses” of stars amongst the most energetic and exotic objects in existence. beginning at the end of the core helium fusion stage in a star’s life, describe in detail the post-main sequence development of both (a) a 1.0 solar mass star, and (b) a 25.0 solar mass star. in what significant ways do they differ? what role does each of these types of stars play in the "star-gas-star" cycle and the evolution of chemical elements in our galaxy?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
