1. The positron or antielectron is the antiparticle or the antimatter counterpart of the electron.
2.The positron has an electric charge of +1e, a spin of 1/2 (same as an electron), and has the same mass as an electron.

When a tire is able to roll, it has vastly less resistance to motion in the direction of rotation than it does in any other direction. Static friction exists if the wheels keep rolling on the ice without locking up, resulting in maximum braking force. However, if the wheels lock up then kinetic friction takes over since there is relative slipping between wheel and ice. This reduces the braking force and the car takes longer to stop.

Biogeography is the study of the distribution of species (biology), organisms, and ecosystems in geographic space and through geological time. There are ten biogeographical zones in India: Trans Himalayan zone, Himalayan zone, Desert zone, Semiarid zone, Western Ghat zone, Deccan plateau zone, Gangetic plain zone, North east zone, Coastal zone and Islands present near the shore line.

Understorey comprises plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade tolerant.
