I would say A, a build up of electrical charges in the clouds
B is close to correct, it’s also the flow of electrical charge between the clouds and the ground
Answer: height = 3.98m
Explanation: by placing the watermelon at a height above the ground, it has a potential energy of the formulae
p = mgh
p = potential energy = 4.61kJ = 4610J
m = mass of watermelon = 118 kg
g = acceleration due gravity = 9.8 m/s²
4610 = 118 * 9.8 * h
h = 4610/ 118 * 9.8
h = 4610/ 1156.4
h = 3.98m
There is no thing here I can answer so imma just say all of the above because I have no idea what else to say so thx for the points
