Answer:
East component is: 18.64 m/s
Explanation:
If the resultant is 32.5 m/s directed 35 degrees east of north, then we use the sin(35) projection to find the east component of the velocity:
East component = 32.5 m/s * sin(35) = 18.64 m/s
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
Huh??????????????????????????
Speed of sound through a medium depends on
● temperature
● density of medium
● speed of wind
● humidy
● moisture
Speed of sound increases with increase in temperature. Because when temperature increases the molecules get higher energy and they vibrate quickly. Due to this vibration sound waves can travel fastly.
