1. Electrostatic charge build-up in clouds - When a neutral (uncharged) cloud swirls and rises rapidly,there is a lot of friction between water molecules and air. If the base of the cloud becomes negativelycharged, why does this mean that the top of the cloud becomes positively charged? Explain.2. Look at the picture below and explain why the earth gets positively charged when a cloud (whosebase is negatively charged) hovers over it? What type of charging process occurs?ایمنیسیصدétrieمنافقين
