Physics It is dangerous to observe Solar eclipse with naked eyes because All radiations from sun initiate chemical reactions in eyes Cosmic rays reach eyes more during the eclipse Ultraviolet radiations from Sun burn our retina Infrared radiations from sun burn our retina All radiations from sun initiate chemical reactions in eyes Cosmic rays reach eyes more during the eclipse Ultraviolet radiations from Sun burn our retina Infrared radiations from sun burn our retina ANSWER DOWNLOAD EXAMIANS APP
Physics On a cold day when a room temperature is 15oC, the metallic cap of a pen becomes much colder than its plastic body, though both are at the same temperature of 15oC, because metals have higher thermal capacity than plastics plastics have a lower density than metals metals are good conductor of heat plastics have a higher thermal conductivity than metals metals have higher thermal capacity than plastics plastics have a lower density than metals metals are good conductor of heat plastics have a higher thermal conductivity than metals ANSWER DOWNLOAD EXAMIANS APP

Physics Planets do not twinkle because They emit light of a constant intensity They are nearer to earth and hence we receive a greater amount of light. They are very far away from the earth resulting in decrease in intensity of light Their distance from the earth does not change with time They emit light of a constant intensity They are nearer to earth and hence we receive a greater amount of light. They are very far away from the earth resulting in decrease in intensity of light Their distance from the earth does not change with time ANSWER DOWNLOAD EXAMIANS APP
