The new earth-Pluto SuperShuttle line boast that it can take you between the two planets (which are about 5.0 hapart in distance) in 2.5 haccording to your watch on board the shuttle. Assume that the shuttle travels at a constant velocity.a.) What time interval must the synchronized space station clocks register between theshuttle’s departure andits arrival at Pluto if the advertisement is true?b.) What is the shuttle’s cruising speed?

Expert Solution

a)

we know the equation

we assume that the accleration and deccleration are very brief so that we spend essentially all the trip at constant velocity.

so, for the interval between leaving the earth and encountering Pluto, we have

this is also the event distance proper time measured by a watch at rest is the event distance

thus

= 2.5 h

therefore the time interval betweent the shuttles departure and its its arrival at pluto is

b)

we have now

or

therefore

v = 0.917 c

Imagine two planets orbiting a star with orbits edge-on to the Earth. The peak Doppler shift for each 75 m/s, but one has a period of 7 days and the other has a period of 700 days. The star has a mass of one solar mass. Assume 1 solar mass equals 2∗10^30. 1.) Calculate the mass of the shorter period planet. (Hint: See Mathematical Insight Finding Masses of Extrasolar Planets) 2.) Calculate the mass of the longer period planet.

A firm can choose between two production technologies for a new product line. If it installs technology 1, its yearly costs will be: ?1=4500+25?+45?2. If it installs technology 2, its yearly costs will be: ?2=400+125?+?2. What is the marginal and average cost of each technology? What is the minimum efficient scale of both technologies? Which technology would the firm prefer (purely from a cost standpoint) if it expects to sell 60 units each year?

If you take a boat from earth and put it on a planet with twice earth’s gravity, what would happen if you tried to float it in water? Hint: Think about the buoyancy force formula. (5 points) 2. You drop a cube of mass 1 kg into a cup of water. It sinks with an acceleration of 2 m/s^2. a. What is the buoyancy force of the water? (4 points) b. What is the density of the water if the...
