Question 3 4 pts I am delivering pizza on Mars. I am given a pizza at Hal’s Gourmet Pizza located on Mars’ Moon Phobos to take down to the surface of Mars. The Pizza weighs 1 Newton (1N) on Phobos. The acceleration due to gravity on Phobos is 0.0057 m/s2. The acceleration due to gravity on the surface of Mars is 3.7 m/s2. How much will the pizza weigh when I get down to the surface of Mars? 0.0057 Newtons O 3.7 Newtons 650 Newtons 155 Newtons O 0.0015 Newtons

Precipitated protein is centrifuged to a total moisture content of 28 wt%. It is then dried in a batch drier for 6 hours under constant drying conditions to 16 wt% (total moisture). The critical moisture content for the solids is 11 wt% (total moisture). The equilibrium moisture content is 4 kg H2O/100 kg dry solid. How long would it take to dry a sample of the same size from a free moisture content of 25 wt% to 4 wt% under the same drying conditions? All given moisture contents are in dry basis. Assume that the drying rate (in the falling rate period) is a linear function through the origin
