Physics Why does bleeding occur through the nose in high mountainous regions ? The blood pressure fluctuates and finally decreases drastically The pressure at high altitudes is greater than that on the plains The blood pressure of a person increases at high altitudes The pressure of blood in capillaries is greater than the outside pressure The blood pressure fluctuates and finally decreases drastically The pressure at high altitudes is greater than that on the plains The blood pressure of a person increases at high altitudes The pressure of blood in capillaries is greater than the outside pressure 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 higher thermal conductivity than metals plastics have a lower density than metals metals are good conductor of heat metals have higher thermal capacity than plastics plastics have a higher thermal conductivity than metals plastics have a lower density than metals metals are good conductor of heat ANSWER DOWNLOAD EXAMIANS APP
