A new client named Elon Musk is interested in transporting some soil to Mars with his new Falcon Heavy rocket to set up a vegetable growth experiment. As part of the schematics he needs you to calculate some of the physical properties of the soil his team has selected. Elon has collected the following data for you based on a subsample of the soil:

The subsample is 95 cm3 in total volume. When it is oven dry the sample weighs 143g. After completely saturating the sample with water it weighs 190g. After allowing the sample to drain overnight it weighed 170g. Adding the oven dry sample causes the water level in a graduated cylinder to rise 45mL. (Show all work/units for full credit!)

A. After arriving on Mars, how many kilograms of water would need to be added to 1.5 cubic meters of oven dry soil to bring the moisture content up to field capacity in order to start the vegetable experiment?

B. After arriving on Mars, how many liters of water would need to be added to 1.5 cubic meters of oven dry soil to bring the moisture content up to field capacity in order to start the vegetable experiment?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
