Several planets (jupiter, saturn, uranus) possess
nearlycircular surrounding rings, perhaps composed of material
thatfailed to form a satellite. in addition, many galaxiescontain
ring-like structures. consider a homogeneous ring ofmass m and
radius r.
a.)what gravitational attraction does it exert on a particleof
mass m located a distance x from the center of the ring alongits
axis?
b.) supposes the particle falls from rest as a result of
theattraction of the ring of matter. find an expression for
thespeed with which it passes through the center of the ring.

Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. you send the clock to a location on the moon where the magnitude of the acceleration due to gravity is 1.65 m/s2.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
