Size of galaxies. a. 2. the sun is about 8.0 kpc from the center of our galaxy. plot the apparent size (in arcseconds) of this separation as a function of redshift from redshift 0.1 to 10.0. what is the redshift where the apparent separation is a minimum? imagine that we wish to study the kinematics of a galaxy. we have a spectrograph (ifu) that can simultaneous measure the spectrum at points (and therefore measure the radial velocity as a function of position.) if we are limited in our spatial resolution to 1 arcsecond x 1 arcsecond by seeing for ground-based observations, at what redshifts is it practical to study galaxy kinematics on 1 kpc scales? what about if we instead have a space- based system (like james webb space telescope) that has a resolution of 0.1 arcseconds? now plot the separations for the alternative flat cosmology with a hubble constant of 70 km/s/mpc, a zero cosmology constant, and omega matter equal to one. b. c. d.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
