Could capillary action be used to move fluids in a "weightless" environment, such as in an orbiting space probe?
Is capillary action due to cohesive or adhesive forces, or both?
Milk is ___ dense than the cream that floats on top. (3.7)
How do jogging on soft ground and wearing padded shoes reduce the pressures to which the feet and legs are subjected?
The outward force on one end of an air tank was calculated in Example 11.2. How is this force balanced? (The tank does not accelerate, so the force must be balanced.)
Verify that the flow of oil is laminar (barely) for an oil gusher that shoots crude oil 25.0 m into the air through a pipe with a 0.100-m diameter. The vertical pipe is 50 m long. Take the density of the oil to be 900 kg/m3 and its viscosity to be 1.00(N/m2) s (or 1.00Pa s).
Bone has a Youngs modulus of 18 109 Pa. Under compression, it can will island a stress or about 160 106 Pa before breaking. Assume that a femur (thigh bone) is 0.50 m long, and calculate the amount of compression this bone can withstand before breaking.
If a submerged object displaces a volume of liquid equal to its weight and is then released, what will the object do? (3.6) (a) rise to the surface (b) sink (c) remain at its submerged position
The true weight of an object can be measured in a vacuum, where buoyant forces are absent. A measurement in air, however, is disturbed by buoyant forces. An object of volume V is weighed in air on an equal-arm balance with the use of counterweights of density . Representing the density of air as air and the balance reading as Fg, show that the true weight Fg is Fg=Fg+(v-Fgg)airg
Is surface tension due to cohesive or adhesive forces, or both?
Verify that flow of oil is laminar for an oil gusher that shoots crude oil 25.0 m into the air through a pipe with a 0.100-m diameter. The vertical pipe is 50 m long. Take the density of the oil to be 900 kg/m3 and its viscosity to be 1.00(N/m2)s (or 1.00Pas ).
