Ametal conduit will be used as a pathway for wiring through a concrete block. the conduit is a 4 foot long rod with an outer diameter of 2.2 inches and an inner diameter of 2 inches. what is the volume of metal in the conduit in cubic centimeters?

The volume of a cylindrical conduit,

where is the inner radius, is the outer radius, h is the length.

First of all, we would covert each parameter into centimeters.

length of the conduit,

outer radius,

inner radius,

Insert the values in the volume formula,

Hence, the volume of metal in the conduit is 510. 12 cubic centimeters.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
