Aman jumps off a bridge 80 metres above a river below. his feet are tied by a bungee rope that is 40 metres long when not stretched. at the bottom, his head just touches the water. use calculations based on energy to work out where he will finally come to rest when he stops bouncing. ignore the man's height.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
