Amodel airplane is flying horizontally due north at 44 mi/hr when it encounters a horizontal crosswind blowing east at 44 mi/hr and a downdraft blowing vertically downward at 22 mi/hr. a. find the position vector that represents the velocity of the plane relative to the ground. b. find the speed of the plane relative to the ground.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
