A 0.403 kg mass is attached to a spring and undergoes simple harmonic motion with a period of 0.78 s. The total energy of the system is 4 J. Find the amplitude of the motion. Answer in units of m.

Rising Air creates low pressure while sinking air creates high pressure. WIth high pressure, sinking air suppresses weather development. High air pressure produces clear sky, dry and stable weather. In a low pressure zone, wind is circulated onwards and upwards rapidly. As a result, air rise and cools. Clouds and precipitate are formed
