If smooth spherical ball of brass material having a radius of 3mm fall through certain liquid having coefficient of viscosity of 8x 10'NS/m. If the density of the brass
material is 8.6 x10 kg/m', estimate its terminal velocity
+)? Assume that the density of the liquid is 5.7x10'kg/m.​

Pls me i need this ! each cell has genes activated depending on it's job and what kind of cell it is. it is the presence of that causes the repressor protein to fall off and unblock the gene on the lac operon. if a gene is turned on then it is being an additional circular chromosome found in some bacteria that is used in genetic engineering.
