Sabiendo que la masa de Marte es de 6,42 · 1023 kg y que su diámetro medio es de 6794 km, calcula el valor de la aceleración de la gravedad sobre la superficie del planeta. Datos: Constante de gravitación universal = 6,67 · 10–11 Nm2/kg2.

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 !
