(I) If you tried to smuggle gold bricks by filling your backpack, whose dimensions are 54cm× 31cm× 22cm what would its mass be?
How high should the pressure head be if water is to come from a faucet at a speed of \({\bf{9}}{\bf{.2\;m/}}{{\bf{s}}^{\bf{2}}}\) Ignore viscosity.
An object that can float in both water and in oil (whose density is less than that ofwater) experiences a buoyant force that is
(a) Greater when it is floating in oil than when floating in water.
(b) Greater when it is floating in water than when floating in oil.
(c) The same when it is floating in water or in oil.
(I) Estimate the pressure exerted on a floor by (a) a one-pointed heel of area = 0.45 cm2, and (b) one wide heel of area 16 cm2, Fig. 10–48. The person wearing the shoes has a mass of 56 kg.
An airplane has a mass of \({\bf{1}}{\bf{.7 \times 1}}{{\bf{0}}^{\bf{6}}}\;{\bf{kg}}\) and the air flows past the lower surface of the wings at 95 m/s. If the wings have a surface area of \({\bf{1200}}\;{{\bf{m}}^{\bf{2}}}\), how fast must the air flow over the upper surface of the wing if the plane is to stay in the air?
