An earth-orbiting satellite has an elliptic orbit with a semimajor axis of 1.05 du where 1 du is equal to 1 earth radius. when the satellite is at the end of the semi-minor axis, it receives an impulsive velocity change (a fuel burn) just sufficient to place it on a parabolic escape trajectory. what is the magnitude of the velocity change? compute the answer indu/tu and then convert to km/s. an earth-orbiting satellite has an elliptic orbit with a semimajor axis of 1.05 du where 1 du is equal to 1 earth radius. when the satellite is at the end of the semi-minor axis, it receives an impulsive velocity change (a fuel burn) just sufficient to place it on a parabolic escape trajectory. what is the magnitude of the velocity change? compute the answer indu/tu and then convert to km/s.

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
