What is the specific fuel requirement for flight under vfr at night in an airplane?
a) enough to fly to the first point of intended landing and to fly after that for 45 minutes at normal cruising speed.
b) enough to complete the flight at normal cruising speed with adverse wind conditions.
c) enough to fly to the first point of intended landing and to fly after that for 30 minutes at normal cruising speed.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
