Which statement is true for a sound wave entering an era of a warmer air ? a. the wave travels faster and with the same wavelength b. the wavelength travels at the same speed but with an increased wavelength c. the wave travels at the same speed and with the same wave length d. the wave travels slower and with an increased wavelength e. the wave travels faster and with an increased wavelength

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
