The correct answer is (B) : LNG-20.
The correct answer is: (B) LNG-20.
An example of a hormone-releasing intrauterine device (IUD) is LNG-20. LNG-20 is a type of intrauterine system that releases the hormone levonorgestrel (LNG) into the uterus. This hormone is a synthetic form of progesterone, which works to prevent pregnancy by thickening cervical mucus, thinning the endometrial lining, and inhibiting ovulation.
The LNG-20 IUD is a long-acting, reversible contraceptive method that can provide protection against pregnancy for up to five years. It is highly effective and often preferred by women who want a hormone-based contraceptive option without the need for daily pills. Hormonal IUDs, like LNG-20, have a lower risk of side effects compared to other hormonal methods like the birth control pill.
Thus, LNG-20 is a hormone-releasing IUD used for contraception.
A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
