The criteria for a new tablet are that the tablet should include a front and rear camera, the battery should last at least 8 hours, and the tablet should have at least 8 gigabytes of storage. The new design has a constraint that it must cost less than $100 to purchase. The table shows information about for competing designs. Tablet Designs

Design Cost Storage (GB) Battery Life (Hours) Front and Rear Camera
Design 1 $85 6 7 yes
Design 2 $90 8 8 yes
Design 3 $120 10 10 yes
Design 4 $65 5 8 no
Drag and drop the Yes and No responses into the correct boxes to evaluate whether each design meets the criteria and the constraint.

What precautions should you take to prevent injuries when dealing with heavy loads?

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
