A mercury manometer is connected to a container of gas.
a) the height of the mercury column on the side connected to the gas is 22cm (measured from the bottom of the manometer). what is the height of the mercury column on the open side if the gauge pressured is measured to be 13.3kPa? answer is 32cm
b) if the gauge pressure of the gas doubles, what are the new heights of the two columns?
A car is travelling at a constant speed of 32m/s on a highway. At the instant this car passes an entrance ramp, a second car enters the highway from ramp.
Let the drag force on a ball of mass m moving through air in the gravity-free bubble include both "viscous" drag F1=-kv, Find the velocity v of a ball thrown with initial speed v0.
A 0.12-kg ball is placed in a shallow wedge with an opening angle of 120°, as shown in the figure. For each contact point between the wedge and the ball, determine the force exerted on the ball. Assume the system is frictionless. Find contact force o..
