A rigid tank contains 1.50 moles of an ideal gas. Determine the number of moles of gas that must be withdrawn from the tank to lower the pressure of the gas from 25.0 atm to 5.00 atm. Assume the colume of the tank and the temperature of the gas remain constant during this operation.

A sample of gas expands from V1=1.0m³ and
p1=10 Pa to 4.0 m³ and p2=10Pa along path B
in the P-V diagram in Fig. 3. It is then compressed back to V1
along either path A or path C . Compute the net work done by the
gas for the complete cycle along (a) path BA and (b) path BC .
Physics of the Universe question :
Topic : Astrometry
(a) Ignoring proper motion, determine the apparent position of a star as a function of time as observed from Earth, if it is located at (i) the ecliptic pole (ii) the ecliptic plane.
(b) Including proper motion determine the apparent position of a star, located on the ecliptic pole, as a function of time. Take the direction of the proper motion to be your x-axis.
In Drosophila, brown body is wild type plus dominant to yellow body, and normal wings is wild type plus dominant to vestigial wings. A cross was made between a yellow-bodied male with vestigial wings and a wild-type female. The F1 generation consisted of wild-type males and wild-type females.
a. Define allele symbols for both genes for the moment, assuming that both genes are autosomal.
b. Assuming both genes are autosomal, what is the genotype of the parents and the F1 generations.
The F1 males and females were crossed and the F2 progeny consisted of: 16 yellow-bodied males with vestigial wings ,48 yellow-bodied males with normal wings, 15 brown-bodied males with vestigial wings, 49 wild type males ,31 brown-bodied females with vestigial wings, 97 wild-type females
c. Given this data, determine if body color is autosomal or sex-linked. Support your answer.
d. Given this data, determine if wing shape is autosomal or sex-linked. Support your answer.
e. Redefine your allele symbols to reflect sex-linkage if necessary and determine the following: Genotype of the female parent: Genotype of the male parent: Genotype of the female F1 Genotype of the male F1
f.Genotypic class of each of the different phenotypes found in the F2: Show work on extra pages if needed yellow-bodied males with vestigial wings yellow-bodied males with normal wings brown-bodied males with vestigial wings wild type males wild-type females
A friend tells you that they have found a cure for acne on the Internet. Having suffered from outbreaks well into adulthood, you scoff at this new scam because it’s another expensive cream that probably will not work.
Explain how acne can result from the normal microbes present on the skin.
(The mass of Mercury is 3.3 1023 kg and its radius is 2.4 106 m.) N (b)Calculate the magnitude of the gravitational force exerted by the human on Mercury. N (c) For comparison, calculate the approximate magnitude of the gravitational force of this human on a similar human who is standing 3 meters away. N (d) What approximations or simplifying assumptions must you make in these calculations?
The strands of DNA can be separated by heating the DNAsample. The input heat energy breaks the hydrogen bondsbetween base pairs, allowing the strands to separate from one another. Suppose that you are given two DNA samples. One has a G + C content of 70% and the other has a G + C content of 45%. Which of these samples will require a higher temperature to separate the strands? Explain your answer.Please choose one of the questions below and provide your answer in a 1-2 page paper (not including reference page), double-spaced, and 12-point font.. NOTE: Please provide 1 textbook and 1 website sources. (Double space please).
