As shown in the diagram, the forward thrust of the engine is 85N. The wind and air resistance is providing 100 N of force to the reverse. What is the net force on the airplane? ● 85 N right

● 100 N left

● 185 N right

● 15N left​

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?
