Find the magnitude of the sum of two vectors; A is 5 km , and B is 7 , when the angle btween them is 120

6.24 km

Explanation:

Given

The magnitude of the first vector(say)

the magnitude of the second vector(say)

the angle between them is

The resultant vector magnitude is given by

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.
