1. A turning fork vibrating at a frequency of 600 m/s is placed in a basin of water is placed in a basin of water. Sound waves are produced having a wavelength of 2.5 m. What is the velocity of sound in the water? Questions:
a. What is the frequency of water wave? b. What is the wavelength of the water wave?
c. What is the formula for solving the speed?
d. Solve for the velocity of the wave? ( show the solution)

please can you answer this, I just really need it

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.

What is the equation for electrical work?

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
