A 23.0-kg cannonball is fired from a cannon with muzzle speed of 1 050 m/s at an angle of 34.0° with the horizontal. A second ball is fired with the same initial speed at an angle of 90.0°. Let y = 0 at the cannon.

Use the isolated system model to find the maximum height reached by each ball.

frequency or wavelenth of em radiation in a vacuum

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.
