Required information
suppose you have a filling in one of your teeth, and, while eating some ice cream, you suddenly realize that the filling
came out. one of the reasons the filling may have become detached from your tooth is the differential contraction of the
filling relative to the rest of the tooth due to the temperature change.
find the change in volume for a metallic dental filling due to the difference between body temperature (37.0°c) and the temperature of
the ice cream you ate (-9.2°c). the initial volume of the filling is 320 mm, and its expansion coefficient is a = 420 x 10-6k-1
mm

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
