A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
Infertility is described as not being able to get pregnant in spite of having frequent, unprotected sex for not less than a year for most couples. Infertility may result from an issue with either you or your partner or a combination of factors that stops a pregnancy.
The major symptom of infertility is not getting pregnant. There may be no other apparent symptoms. Sometimes, women with infertility may have irregular or missing menstrual periods. In some cases, men with infertility may have some signs of hormonal issues, like changes in hair growth or sexual function.
