Asound wave traveling through a certain freshwater lake has a frequency of 349.2 hz and a wavelength of 4.25 m. if the water conditions are held constant, all sound waves will travel at the same speed through water. use this fact to calculate the wavelength of a sound wave with a frequency of 415.3 hz. (round all answers to 3 sigificant figures).

Which property of fossils allow scientists to determine the relative rock ages..

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
