Abat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. if bats emit a chirp at a frequency of 5.59 104 hz, and if the speed of sound in air is 343 m/s, what is the smallest insect a bat can detect? answer in units of mm

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
