Just because she likes these numbers, dr. hoffman decides to develop a new linear temperature scale in which water freezes at –182.8°hand boils at –29°h. a)what is a comfortable room temperature on the hoffman scale? (assume a constant standard pressure, and be sure to specify what “comfortable room temperature” means to you.) b)what does a temperature difference of 5f° equal on the hoffman scale? c)supposeyou have arectangular plate that initially has area ab= 1.9 m2. the coefficient of linear expansion for the materialis622.0 10c−. you heat it until its temperature is 81.5 h° greater than before. after heating, side ais longer by aand side bis longer by b. what is the change in area of the plate? hint: assume both changes in length are small compared with the original lengths.

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?

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
