Sharvari Kuber answered |
In sterilisation method method, tubectomy or vasectomy is used in which the fallopian tube and vas deferens are cut respectively. This prevents the transfer of sperms in males and ova in females for fertilisation permanently. So this is the safest method.

Preeti Iyer answered |
The electric dipole moment per unit volume is called polarization or polarization density (vector p).
It is always directed from negative charge to positive charge.
If there are N atoms per unit volume than
vector p = N (vector p)
where p is the electric dipole moment of individual atom.

Correct answer is option 'B'. Can you explain this answer?
Which of the following relations are not correct?
a)
b)
c)
d)
|
Nandini Iyer answered |
The correct answer is Option B
k =G*l/A (Since, G = 1/R)
= l/AR
Therefore, kR = l/A
So, l/A = kR not k/R
k =G*l/A (Since, G = 1/R)
= l/AR
Therefore, kR = l/A
So, l/A = kR not k/R

Lavanya Menon answered |
- When an external electric field is applied to the conductor, the free electrons in the conductor move in an opposite direction to that of the applied electric field.
- This movement of electrons induces another electric field inside the conductor which opposes the original external electric field.
- This continues until the induced electric field cancels out the external field.

|
Gaurav Kumar answered |
- Polar molecules occur when two atoms do not share electrons equally in a covalent bond.
- The oxygen side of the molecule has a slight negative charge, while the side with the hydrogen atoms has a slight positive charge.
- Ethanol is polar because the oxygen atoms attract electrons because of their higher electronegativity than other atoms in the molecule.
The dielectric Constant of a metal is- a)infinite
- b)zero
- c)equal to one
- d)less than one
Correct answer is option 'A'. Can you explain this answer?
The dielectric Constant of a metal is
a)
infinite
b)
zero
c)
equal to one
d)
less than one
|
Nabanita Sen answered |
An electric field (E) is generated both inside the metal and outer (plates) which are equal in magnitude but opposite, making the net resultant field (Er) in the metal to be zero. Hence, the derived dielectric constant (K) of the metal is (E/Er = E/0) which is infinity. This is why the dielectric constant is infinity.

The cell constant G* is calculated by the expression:- a)l/A
- b)A.l
- c)l.A
- d)A/l
Correct answer is option 'A'. Can you explain this answer?
The cell constant G* is calculated by the expression:
a)
l/A
b)
A.l
c)
l.A
d)
A/l
|
|
Preeti Iyer answered |
The quantity l/A is called cell constant denoted by the symbol, G*.It depends on the distance between the electrodes and their area of cross-section and has the dimension of length–1 and can be calculated if we know l and A. Measurement of l and A is not only inconvenient but also unreliable. The cell constant is usually determined by measuring the resistance of the cell containing a solution whose conductivity is already known. For this purpose, we generally use KCl solutions whose conductivity is known accurately at various concentrations and at different temperatures. The cell constant, G*, is then given by the equation:
G* =l/A= Rκ
G* =l/A= Rκ

Sinjini Yadav answered |
Explanation:
Statement I: Oral contraceptive pills are a safeguard against AIDS and sexual diseases besides checking pregnancy.
- This statement is incorrect. Oral contraceptive pills are primarily designed to prevent pregnancy by inhibiting ovulation, thickening cervical mucus, and thinning the uterine lining. They do not protect against sexually transmitted infections (STIs) or AIDS.
- To prevent the transmission of STIs, including AIDS, the use of condoms is essential. Condoms act as a barrier method that can help reduce the risk of contracting infections during sexual activity.
Statement II: Copper-T is a physical barrier preventing the body fluid of two partners to come in contact.
- This statement is correct. Copper-T, also known as an intrauterine device (IUD), is a form of birth control that is inserted into the uterus. It works by releasing copper ions that are toxic to sperm, preventing fertilization.
- Copper-T does not physically prevent body fluids of partners from coming into contact, but it acts as a physical barrier for sperm, thus preventing pregnancy.
Therefore, the correct answer is:
d) Statement I is incorrect but Statement II is correct.

Siddharth Yadav answered |
Understanding Periodic Abstinence
Periodic abstinence is a natural contraceptive method based on monitoring the menstrual cycle. The goal is to avoid sexual intercourse during the fertile window when conception is most likely to occur.
Key Points about Ovulation
- Ovulation Timing: Ovulation typically occurs around the midpoint of the menstrual cycle, approximately 14 days before the start of the next period in a typical 28-day cycle. This is when an egg is released from the ovary and is available for fertilization.
- Fertile Window: The fertile window includes the days leading up to and including ovulation, usually spanning about 6 days. This is when sperm can survive in the female reproductive tract, increasing the chances of fertilization.
Why Option B is Correct
- Abstinence During the Fertile Period: Couples practicing periodic abstinence avoid intercourse specifically during the days when ovulation is most likely to occur (option B). This strategy reduces the risk of unintended pregnancy by timing sexual activity around the woman's fertile days.
- Menstrual Flow: Abstaining during menstrual flow (option A) does not prevent pregnancy since ovulation occurs later in the cycle.
- Corpus Luteum Activity: While the corpus luteum is active during the luteal phase, it is too late for preventing pregnancy if ovulation has already occurred (option C).
- Proliferative Phase: The proliferative phase focuses on the buildup of the uterine lining and does not directly correlate with avoiding conception (option D).
Conclusion
To effectively use periodic abstinence as a contraceptive method, couples must understand their menstrual cycle and identify the days when ovulation is most likely to happen. This knowledge helps them to make informed decisions about when to abstain from intercourse to prevent pregnancy.

Assertion (A) and Reason (R) Explanation:
Assertion (A): Women are at the peak of conception on the 14th day of ovulation.
Reason (R): Vasectomy is a method normally employed to avoid conception in females.
Explanation:
- Assertion (A) is true: Women are indeed most fertile around the time of ovulation, typically occurring around the 14th day of the menstrual cycle.
- Reason (R) is false: Vasectomy is not a method used to avoid conception in females. It is actually a surgical procedure for males that involves cutting or blocking the vas deferens to prevent the release of sperm during ejaculation. This procedure does not affect female fertility directly.
Therefore, while the assertion regarding female fertility around ovulation is accurate, the reason provided is incorrect. Women's fertility and conception are not influenced by vasectomy, as it is a male sterilization procedure.
