The technique recommended by doctors to address infertility is (3) ART, which stands for Assisted Reproductive Technology. ART encompasses a variety of methods and procedures designed to assist couples or individuals in conceiving a child when they face fertility challenges.
Some common ART procedures include:
In vitro fertilization (IVF): Eggs are retrieved from the woman's ovaries and fertilized with sperm in a laboratory setting. The resulting embryos are subsequently transferred to the woman's uterus.
Intracytoplasmic sperm injection (ICSI): A single sperm is directly injected into an egg to facilitate fertilization.
Intrauterine insemination (IUI): Sperm is collected, processed, and then inserted directly into the woman's uterus during her fertile period.
Gamete intrafallopian transfer (GIFT): Both eggs and sperm are collected and placed together into the woman's fallopian tubes, allowing fertilization to occur naturally.
Zygote intrafallopian transfer (ZIFT): Fertilized embryos (zygotes) are transferred into the woman's fallopian tubes.
Let's define each acronym to understand the context:
Therefore, the technique advised by a doctor to overcome the problem of infertility is ART (Assisted Reproductive Technology).
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
