Astronomy New stars can form inside a doud of interstelar gas when a cloud fragment, or dump, has a mass M greater than
the jeans mass M, The Jean's mass is M,=100n (T+273)
where n is the number of gas molecules per cubic centimeter
and T' is the gas temperature in degrees Celsius. A gas dump has
M=137,11 1000, and T-263. Will the dump form a star
Justify your answer

so what is the question

step-by-step explanation:

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.

it’s the first one your welcome
