Suppose that a, b, m, and n are integers (n, m positive) and suppose we know a = b (mod n) and nm Can we safely conclude that a = b (mod m)? (a) True by transitivity (b) False because I can find small integers for which it fails. True, because congruence mod n has more equivalence classes so the conclusion is just a weaker (c) version of the hypothesis. True, because congruence mod n has fewer equivalence classes so the conclusion is just a weaker (d) version of the hypothesis. Save & Grade Single attempt Save only 1 point available for this attempt

A pawn shop dealer has just purchased a ring that he was told was 24K Gold, which is pure Gold-197. He happens to have a mass spectrometer for just these occasions. He scraped a tiny sample off the ring and analyzed it in the mass spectrometer. The following spectra was generated. Determine if this was 24K Gold. If it was not, indicate the other metal(s) present, and the specific isotope of that element. Back up your answer using the information provided in the spectra and the periodic table. 100 Relative abundance (96) 50 o 65 107 197 Mass-to-charge ratio

A "calorie" is a unit of energy, defined as the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. The nutritional labels on food products typically tell you how many calories of digestible energy are in one serving of food, where "digestible" means that the energy stored in the chemical bonds of the molecules comprising the food can be extracted by your body. (Water for example has energy, but that energy is not chemically accessible via digestion.) To simplify understanding for typical consumers, the "calories" reported on nutritional labels actually represent kilocalories: a 170 calorie can of beer actually contains 170,000 calories of digestible energy i) If a student foolishly decides to binge drink 21 beers on their 21t birthday, how many gallons of water could they have heated from room temperature (24 C) to boiling (100 C) using an equivalent amount of digestible energy in the beer? Recall that one gallon of water is roughly 8 pounds ii) What is this energy equivalent to in BTU? A "BTU" or British Thermal Unit is also a unit of energy, defined as the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit iii) If you had purchased an equivalent amount of electrical energy in kW-hr from the utility company, how much would you have to pay? Is this cheaper than buying beer? A kW-hr ypically costs 10 cents

Use a quarter-wavelength transformer to match a lossless transmission line of characteristic impedance of300ohmsto a resistive load of75ohms. Find the impedance of the transformer. Determine the standing wave ratio in the main line and the standing wave ratio in the transformer. What would be the physical length of the quarter-wave transformer at a frequency of100MHz, assuming that the transformer is a coaxial cable with dielectric constant equal to 16 ?
