Two spheres made of different materials have their masses in the rato of 1:2. If the diameter of the first sphere is equal to the radius of the second sphere, tehn determine the ratio dinsities volume of sphere = `(4)/(3) pir^(3)` |
|
Answer» Density =` (mass)/(volume)` (ii) `(d_(1))/(d_(2))=((m_(1))/(v_(1)))/(m_(2)/(v_(2)))=(m_(1))/(m_(2))xx(v_(2))/(v_(1))` = `=(m_(1))/(m_(2))xx((4)/(3)pir_(2)^(3))/((4)/(3)pir_(1)^(3))=(m_(1))/(m_(2))xx((r_(2))/(r_(1)))^(3)` (iii) 4 : 1 |
