A particle of mass m moves under the central field
F = -m (γe-∈r/a/r2)r^,
where γ , a and ∈ are positive constants. Find the apsidal angle for a nearly circular orbit of radius a. When ∈ is small, show that the perihelion of the orbit advances by approximately π∈ on each revolution.
A converging nozzle with diameter 6cm is attached to a resevoir maintained at 30-c and 150kpa absolute. Determine the mass flux using the appropriate properties table.

An unsuited free diver can work in a pressure of up to 490KN/m^2 and a suited diver in pressure of up to 1815 KN/m^2. Calculate the maximum depths at which they might work in sea-water which has a specific gravity of 1.03.
the compressor of a refigerator compresses saturated r-134a vapor at -10 c to 800kpa. how much work does this require
The magnitudes of a pnp transistor's emitter and base currents are 6 and 0.1 mA, respectively. The magnitudes of the voltages across the emitter-base and collector-base junctions are 0.65 and 7.3 V. Find

what is the gauge pressure of the gas in this mercury manometer if h 81 mm and the atmospheric pressure is 773 mmhg?
In a certain chemical plant, a closed tank contains ethyl alcohol to a depth of 50 ft. Air at a pressure of 25 psi fills the gap at the top of the tank. Determine the pressure at the closed valve attached to the tank 10 ft above its bottom.
Let H/ z ) be the system function of a discrete-time prototype low-pass filter. Consider a new discrete-time low-pass filter whose system function H( z ) is obtained by replacing z in H/ z ) with ( z - a )/{1 -az ), where a is real.
