As computer structures get smaller and smaller, quantum rules start to create difficulties. Suppose electrons move through a channel in a microprocessor. If we know that an electron is somewhere along the 50 nm length of the channel, what is the uncertainty in the speed? If the electron was moving at the fastest speed consistent with this range, how long would it take to traverse the 50 nm channel?

Which statements describe the relationship between science and society? check all that apply. science is influenced by the needs of society. science and society are independent. science seeks ways to meet the needs of society. scientists find new ways to address societal concerns. scientists improve existing products.

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
