A uniform rectangular plate of length B = 18 cm and height A = 36 cm has a rectangular corner cut out of it of length D = 9 cm and height C = 5 cm. The plate is made of a material of area mass density σ. For this problem we set the origin at the lower left corner of the plate with the x-axis horizontal pointing right and the y-axis vertical pointing up.
Part (a) Calculate the value of the y-coordinate, in centimeters, for the center of mass of the plate.
Part (b) Calculate the value of the x-coordinate, in centimeters, for the center of mass of the plate.

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 !
