A metal conduit will be used as a pathway for wiring through a concrete block. The conduit is a 4 foot long rod with an outer di
AlekseyPX

Answer:510. 12 cm^3

The volume of a cylindrical conduit, V=\pi (r_2^2-r_1^2) h

where r_1 is the inner radius, r_2 is the outer radius, h is the length.

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

length of the conduit, h=4 ft=4\times 30.48 cm=121.92 cm

outer radius, r_1=2.2/2 in =1.1 in= 1.1\times 2.54 cm=2.79 cm

inner radius, r_1=2/2 in =1 in= 2.54 cm

Insert the values in the volume formula,

V=3.14 \times (2.79^2-2.54^2) \times 121.92 cm^3=510. 12 cm^3

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

Eduardwww [97]

Complete Question

A proton is located at <3 x 10^{-10}, -5*10^{-10}  , -5*10^{-10}> m. What is r, the vector from the origin to the location of the proton

Answer:

The  vector position is   \=r=

Explanation:

From the question we are told that

  The  position of the proton is m

Generally the vector location of the proton is mathematically represented as

       \= r =

So substituting values

     \=r=
