Consider steady, two-dimensional heat transfer in a long solid bar (k = 100 W/mºC)with a 1 m × 1 m cross section. There is no energy generation in the bar. As shownbelow, each surface of the bar is maintained at a uniform temperature. Determinethe unknown center temperature To (ºC) using the following methods

Henry, whose mass is 95 kg, stands on a bathroom scale in an elevator. the scale reads 830 n for the first 2.4 s after the elevator starts moving, then 930 n for the next 2.4 s. part a what is the elevator's speed 4.8 s after starting? express your answer with the appropriate units.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
