A wire whose mass per unit length is 10^-3 kg/m is stretched by a load of 4kg over the two bridge os sonometer 1m apart. if it is struck at its middle point, what will be a. wavelength of its subsequent fundamental vibration b. the fundamental frequency of the note emitted if the wire struck at the point near one bridge what further frequency might be heard? ( assume g= 10m/s^2​

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a. true or b. false

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
