1. A quasar("quasi-stellar radio source") is a star like object. we would expect one of the wavelength emitted by a quasar to be about 656nm. How ever, we measure this wavelength to be 760nm. How fat are quasars moving relative to us. hint use doppler effect.

2.sunlight (400nm-700nm) going through a diffraction grating results in an interference pattern in the form of a ranbow,

a. which end of the spectrum, red or violet, is closer to the central maximum? explain.

b. what color is the central maximum? why?

1. Denis Shapovalov is a young Canadian tennis star. We would like to estimate the true mean speed of all of Shapovalov's serves. Speeds of his serves follow a normal distribution with standard deviation 15 km/h. What sample size is required to estimate μ to within 2 km/h with 94% confidence? Question 33 options: 205 199 211 208 202 2. We would like to estimate the true mean duration of all Major League Baseball games. Game durations are known to...

Could a star ever move in retrograde motion? Would you ever expect a star to significantly change its position in the sky relative to other stars and constellations? Why does a planet that we can observe with the naked eye do these things while stars do not?

1) Suppose there is an decrease in the price of steel. We would expect the supply curve for steel beams to a. shift leftward b. remain unchanged c. shift rightward d. become flatter 2) There is an inverse relationship between the input prices and supply of the output. In one such scenario lead is input to produce crystals. Assume that the price of lead increases, then the supply of crystals would a. lead to increase b. crystal to decrease c....

1. Why are clades “supported” by one or more synapomorphy? We expect the synapomorphy to be present in all the members of the clade defined by the trait – but the character might be highly modified, or present only a brief developmental stage. [Sometimes the trait is lost altogether, a situation we call being “secondarily lost”] 4. Explain the statement “all clades are subsets of larger clades”. What is the largest clade?

19. We would expect that the level of income that would equate total demand for and supply of money would be: (a) roughly at the level of the Fed’s interest rate target; (b) lower the lower the interest rates; (c) equal to the level that would equate realized investment with realized savings; (d) higher the lower the interest rate (or lower the higher the interest rate). 20. For several decades, Japan was in a “liquidity trap.” Consequently: (a) further monetary...

Often we would like to make the user think we like him/her so we use a friendly prompt to get them to decide if they want to continue a loop. One can make a sentinel using an integer value outside of the expected input range but a more delightful way is to ask politely if: System.out.println("Do you want to play again?); In order to do this we will need a scanner and a do-while loop. For the scanner sometimes the...
