Astronauts use a centrifuge to simulate the acceleration of a rocket launch. The centrifuge takes 40.0 s to speed up from rest to its top speed of 1 rotation every 1.30 s. The astronaut is strapped into a seat 4.20 m from the axis.
A hot-air balloon is rising straight up with a speed of 3.27 m/s. A ballast bag is released from rest relative to the balloon when it is 7.24 m above the ground. How much time elapses before the ballast bag hits the ground?
Calculate the probability of a water molecule being in its flexing ground state and in each of the first two excited states, assuming that it is in equilibrium with a reservoir (say the atmosphere) at 300 K. (Hint: Calculate Z by adding up the fir
