We know that metals sink in water. How do large ship made of metal float on water? |
|
Answer» ship floats on the concept of buoyancy.Buoyancy is the force that CAUSES objects to float. It is the force exerted on an OBJECT that is partly or wholly immersed in a fluid. Buoyancy is caused by the differences in pressure acting on opposite sides of an object immersed in a static fluid. It is ALSO known as the buoyant force. Buoyancy is the phenomena due to Buoyant Force.buoyancy isThe UPWARD force applied by the fluid on the object or the body when an object is put in or submerged in the fluid. |

Answer» The ovary is an organ found in the female reproductive system that produces an ovum. When released, this travels down the fallopian tube into the uterus, where it MAY become fertilized by a sperm. There is an ovary (from Latin OVARIUM 'egg, nut') found on each side of the body. The ovaries also secrete hormones that play a role in the menstrual cycle and fertility. The ovary PROGRESSES through many stages beginning in the PRENATAL period through menopause. It is also an ENDOCRINE gland because of the various hormones that it secretes. |
