While watching a recent science fiction movie, one klingon spaceship blows up a droid spaceship with a laser gun. the klingon crew watches out the port window and covers their ears to muffle the noise from the explosion. scientifically, this scene is inaccurate because
a) light can not reflect off objects in the vacuum of space.
eliminate
b) they would not be able to see anything outside the window.
c) lasers can not be transmitted through the vacuum of space.
d) the sound of the explosion would not be transmitted back to their ship.

Asquare isothermal chip is of width w=5 mm on a side and is mounted in a substrate such that its side and back surfaces are well insulated; the front surface is exposed to the flow of a coolant at tinf=15 °c. from reliability considerations, the chip temperature must not exceed t=85 °c. if the coolant is air and the corresponding convection coefficient is h=200 w/m2 x k, what is the maximum allowable "power" of the chip? if the coolant is a liquid for which h=3000 w/m2 x k, what is the maximum allowable power of the chip?
