Questiondetails:
several planets (jupiter, saturn, uranus) possess nearly
circular surrounding rings, perhaps composedof material that failed
to form a satellite. in addition, many galaxies contain ring-like
structures. consider ahomogeneous ring of mass m and radius
r.
a.)what gravitational attractiondoes it exert on a
particle of mass m located a distance x from thecenter of the ring
along its axis?
b.) supposes the particle falls fromrest as a result of
the attraction of the ring of matter. find an expression for the
speed with which it passes through thecenter of the
ring.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle can be assumed at 30 deg

Gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope

Acertain sound is recorded by a microphone. the same microphone then detects a second sound, which is identical to the first one except that the amplitude of the pressure fluctuations is larger. in addition to the larger amplitude, what distinguishes the second sound from the first one? it is perceived as higher in pitch. it is perceived as louder. it has a higher frequency. it has a longer wavelength.
