Physics Planets do not twinkle because They are nearer to earth and hence we receive a greater amount of light. They emit light of a constant intensity 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 are nearer to earth and hence we receive a greater amount of light. They emit light of a constant intensity 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
Physics A wire of copper having length I and area of cross-section A is taken and a current i is flown through it. The power dissipated in the wire is P. If we take an aluminium wire having same dimensions and pass the same current through it, the power dissipated will be 2P P > P < P 2P P > P < P ANSWER DOWNLOAD EXAMIANS APP
