| A. | \[\theta ={{\int\limits_{0}^{\delta }{\left[ 1-\frac{U}{{{U}_{0}}} \right]}}^{2}}\,dy\] |
| B. | \[\theta ={{\int\limits_{0}^{\delta }{\left[ 1-\frac{U}{{{U}_{0}}} \right]}}^{2}}\,dy\] |
| C. | \[\theta =\int\limits_{0}^{\delta }{\,\frac{U}{{{U}_{0}}}\left[ 1-\frac{U}{{{U}_{0}}} \right]}\,\,dy\] |
| D. | \[\theta =\int\limits_{0}^{\delta }{\,\frac{U}{{{U}_{0}}}\left[ 1-\,{{\left( \frac{U}{{{U}_{0}}} \right)}^{2}} \right]}\,\,dy\] |
