Two circular holes, one larger than the other, are cut in the side of a large water tank whose top is open to the atmosphere. Hole 1 is the larger hole, and hole 2 is the smaller hole. The center of one of these holes is located 8 times as far beneath the surface of the water as the other. The volume flow rate of the water coming out of the holes is the same. (a) Decide which hole (1 or 2) is located nearest the surface of the water. (b) Calculate the ratio of the radius of the larger hole to the radius of the smaller hole, rA/rB.

Water stands at a depth H = 19.5m in a large open tank whose side walls are vertical. A hole is made in one of the walls at a depth of h = 4.50m, below the top water surface. Part A: At what distance A from the foot at the wall does the emerging stream strike the floor? Part B: If you make a hole at a certain position, R becomes the maximum value. Find maximum value of R.

Strings are wound around two pucks identical in size. One string is around the pucks outer rim, while the other is around a smaller axle in the middle, as shown. A radius of the outer rim is twice that of an axle. A side view of the pucks is also included for clarity. You start pulling the pucks with the same force F at the same time, and the pucks are originally at rest. They slide on a frictionless surface....

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
