weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
