What is the difference between solid and hollow cone?​

For a solid-cone spray, fuel is inject anywhere within the cone angle. For a hollow-cone spray, fuel is not injected along the spray centerline, as depicted in this figure. ... For the solid-cone spray "cone" encompasses the whole spray, which is not the case for the hollow-cone spray.

i believe the answer is d.

hope it you! : d

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
