One end of a wire is attached to a ceiling, and a solid brass ball is tied to the lower end. The tension in the wire is 110 N. What is the radius of the brass ball with the answer in m? Brass is 8470 p(kg/m^3)
Please provide the answer with the steps

my previous answer of 0.18 m was unfortunately not correct.

Mind the mass from the tension, M=T/g
M=pV where p is the density. V=(4/3)pi*r^3. Then r=((3/4)T/(g(pi)p))^(1/3)

by no capacity worked with oz. yet wiki says a million ounce = 29.57 m"l. Now remember that a million m"l is a million c"m. So V = sixty seven.6 ounce = sixty seven.6 x29.57 = 1998.9 . i'm going to around it to 2000 m"l. through fact of this you incredibly want m = d x V m = 13.5 x 2000 = 27000 grams of mercury. that's 27 pounds. and prefer 100K in heroes 5 foreign places funds :P .

F = mg = 110N
m = 110N / 9.8 m/s^2
m = 11.22 kg
Volume of sphere = (4/3)πr^3
Density = mass/volume
8470 kg/m^3 = 11.22kg / (4/3)πr^3
solve for r...
