Go to the screen "mars mission landing sites," and and select opportunity landing site (2004). explore all five zoom levels offered, making sure to read the captions at the tops of the screens. based on the information provided, why was the landing site, called meridiani planum, chosen for the opportunity mission? a. the region was already known to have minerals likely to have formed in liquid water. b. the region was in the only part of mars that had not yet been explored. c. the region is near the martian equator, which makes landing easier. d. the region was already known to have very small rocks called "blueberries" that likely formed in liquid water. e. the region has very low elevation, and therefore might once have been in an ancient ocean.

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
