The threshold frequency for metallic potassium is 5.46×10¹⁴ calculate the maximum kinetic energy and velocity that the emitted electron has the wavelength of light shining on the potassium surface is 350nm (me=9.11×10³¹)

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

i believe the answer is true.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
