Each channel in the powerlab is digitized by a 16-bit digitizer. (see the powerlab manual, appendix a).with the input voltage range set at +/- 500mv, what is the smallest difference in voltage that can be resolved? show your calculation.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Which type of basaltic lava flow has a fairly smooth

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
