ENVIRONMENTAL SCIENCE HELP HELP PLEASE!! 3. Use Google Earth to learn how remote-sensing satellites and the GPS are used together in
environmental science. First, find the U. S. location given by the GPS coordinates 35°17' N
latitude and 76°01' W longitude. You can do this by moving the cursor around the globe and
noticing how the display of latitude and longitude at the bottom right changes. Once you
locate the correct general area, zoom in, and then keep moving the cursor until you find the
precise location.

Which accurately compares concave and convex lenses?

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
