Acomposite rod is made from stainless steel and iron and has a length of 0.483 m. the cross section of this composite rod is shown in the drawing below and consists of a square within a circle.

the square cross section of the steel is 1.23 cm on a side. the temperature at one end of the rod is 80.8 °c, while it is 20.0 °c at the other end. assuming that no heat exits through the cylindrical outer surface, find the total amount of heat conducted through the rod in three minutes.

Drag each item into the proper state of matter category.

Diverging mirrors and lenses always produce images

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
