7. What is the force on a 1000 kg elevator that is falling freely under the acceleration of gravity only (10m/s?)?

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
