Two airplanes leave an airport at the same time. the velocity of the first airplane is 700 m/h at a heading of 31.3 the velocity of the second is 570 m/h at the heading of 134° how far apart are they after three hours?

Here in order to find out the distance between two planes after 3 hours can be calculated by the concept of relative velocity

here

speed of first plane is 700 mi/h at 31.3 degree

speed of second plane is 570 mi/h at 134 degree

now the relative velocity is given as

now the distance between them is given as

so the magnitude of the distance is given as

miles

so the distance between them is 2985.6 miles

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:

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
