Asolid brass (bulk modulus 6.7 x 1010 n/m2) sphere is subjected to a pressure of 1.0 x 105 pa due to the earth's atmosphere. on venus the pressure due to the atmosphere is 9.0 x 106 pa. by what fraction r/r0 (including the algebraic sign) does the radius of the sphere change when it is exposed to the venusian atmosphere? assume that the change in radius is very small relative to the initial radius.

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
