Ihave two biophysical chem questions that i have no idea how to get the answer. and show work. you.
1. the unit millimeters of mercury (mmhg) has been replaced by the unit torr: 1mmhg is defined as the pressure at the base of a column of mercury exactly 1 mm high when its density is 13.5951 g/cm3 and the acceleration of free fall is 9.806 m/s2. what is the relation between the two units?
the answer to this question is 1.000 000 143 torr.
2. use the maxwell distribution of speeds to find an expression for the most probable speed of molecules of molar mass m at a temperature t. hint: look for the maximum in the maxwell distribution (the maximum occurs as df/ds = 0).
the answer to this question is c= (2rt/m)^(1/2)

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t β 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12β3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
