6. The Very Long Baseline Array radio interferometer (VLBA) has a longest baseline of 8000 km and can operate at frequencies as high as 44 GHz. The Keck interferometer has a baseline of 100 m and operates at a near-infrared wavelength of 2 micron. (a) Which instrument has the highest angular resolution (smallest diffraction angle)? (b) For the VLBA, what is the smallest distance two radio transmitters could be on the Moon that could still be discerned? Use a lunar distance of 384,000 km.

An automobile has a vertical radio antenna 1.10 m long. The automobile travels at70.0 km/h on a horizontal road where the Earth's magnetic field is 50.0 µT, directed toward the north and downwards at an angle of 65.0° below the horizontal. (a) Specify the direction the automobile should move in order to generate the maximum motional emf in the antenna, with the top of the antenna positive relative to the bottom. (b) Calculate the magnitude of this induced emf.

A sample has a Subscript 6 Superscript 14 Baseline Upper C activity of 0.0020 Bq per gram of carbon. (a) Find the age of the sample, assuming that the activity per gram of carbon in a living organism has been constant at a value of 0.23 Bq. (b) Evidence suggests that the value of 0.23 Bq might have been as much as 37% larger. Repeat part (a), taking into account this 37% increase.

c) Consider a city which is locate on a long (10 km.) thin island. It has a population density of 100 people per km. which is the same everywhere in the city. Each person drinks exactly 1 cup of coffee per day and are willing to pay $5 per cup. The average cost of selling coffee is simple: the minimum average cost is $2 per cup if it sells 200 cups per day and the average cost rises by 10...
