4,186 Joules = 1,000 heat calories = 1 food Calorie Using the above conversions, calculate how many times (and how many flights of steps) a 150 lb person would have to climb the Sears Tower located in downtown Chicago if they ate a 500 Cal piece of apple pie and drank a 150 Cal soft drink. The Sears Tower is 1,450 feet high and has 110 flights of steps. Be sure to use the appropriate SI units!

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

When a metal and an bond they do not share electrons

When a pendulum is held high and taut and then is released, the pendulum begins to swing. what’s the correct order of the energy transformations in this example? (pe stands for potential energy.)
