The top and bottom margins of a poster 6 cm each, and the side margins are 4 cm each. if the area of the printed material on the poster is fixed at 384 square centimeters, find the dimensions of the poster of smallest area. (list the smallest dimension first)

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
