Alarge container is separated into two halves by al= 2.0 cm thick glass divider. the area of the divider is= 0.25 m2and the thermal conductivity of glass isk= 0.90 w/m·k. each side is filled withm= 30 kg of water, specific heatc= 4180 j/kg·k, at different temperatures. initially, the temperature difference is ∆t0= 20 k. how long will it take before the temperature difference is ∆t= 1.0 k

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
