John and Jane are in a 1600 meter race. John Runs at a constant speed of 5.5 m/s. Jane runs at a 6.75 m/s for the first 600 meters, and then 5.0 m/s for the last 1000 meters. How much time did each person take to run the race? who won?

In this thread, i would like you to comment on the nature of light and how operation of telescopes. light has a duality of a particle and a wave; which one affects your life? also how does light interact with optics inside telescopic systems? answer these questions in two paragraphs. then respond the another students response.

Onsider a u-tube whose arms are open to the atmosphere. now, equal volumes of water (ρ = 62.4 lbm/ft3) and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and thus the liquid levels in the two arms are the same. if the fluid height in each arm is 31 in, determine the gage pressure the person exerts on the oil by blowing. (round the final answer to three decimal places.)

Describes how input voltage signals received by a computer are handled through a series of electronic logic circuits maintained in its programmed instructions. these instructions are used to change the input voltage signals, or data, into output voltage signals, or commands.
