Volts and amperage together basically combined in a formula to determine the number of watts, but they are not specifically related to each other. As per Ohm's law V=IR where V is voltage, I is current and R is resistance. since Voltages is equal to current times resistance than makes them directly proportional to each other and therefor related.
Cervical Position. During menstrual bleeding, the cervix is normally low and hard and slightly open to allow the blood to flow out. It feels like the tip of your nose. After your period stops, the cervix remains low and hard and the opening to the uterus (uterine os) remains closed.
The cervix is rigid and closed before pregnancy, but it softens and elongates during pregnancy. However, during labor, the cervix shortens and dilates to allow the passage of your baby. Cervical shortening before 37 weeks of pregnancy increases your risk of giving birth to a premature baby. A baby is usually born about 38 weeks after conception. Although the cervix gradually softens and effaces (decreases in length) as the baby grows bigger in the uterus, it does not open or dilate until you are ready to give birth. If your cervix is short before the 37th week, you may go into preterm labor.
