The electron volt equals 1.602 × 10−12 erg or 1.602 × 10−19 joule.
10. Which of the following is a part of Kidney?
Answer: Each kidney has an outer layer called the cortex, which contains filtering units. The center part of the kidney, the medulla has fan-shaped structures called pyramids.
11. What is convection?
Answer: the process in which heat moves through a gas or a liquid as the hotter part rises and the cooler, heavier part sinks.
12. Unit of momentum:
Answer: The units for momentum would be mass units times velocity units. The standard metric unit of momentum is the kg•m/s.
