1. Sportsmen wear shoes with spikes because these "spikes" create better grip when running. The force of friction between and shoes and spikes increased, forming better grip, most notably you see this when playing on grass. Horses similarly have special shoes put on that also help with grip.
2. No, it is unsafe to repair electrical appliances outdoors during heavy downpour. This is due to rain water containing dissolved salts, thus, rainwater can conduct electricity, and rather well. In short, electricians risk electrical shocks when working outdoors during the rain.
3. Jammu and Kashmir, Gujarat, and Assam are the three most likely places in India to have earthquakes.
4. A constellation is a group of stars forming a pattern. Traditionally, these are named after the apparent form or shape it creates, sometimes named after a mythological figure, for example, Orion, and Scorpius are two.
5. While you cannot "see" stars move because of how far away they are, they do move slowly over the course of the night, but it is not the stars themselves moving, but rather it is the rotation of the planet itself that makes the stars appear to move.
