The variation in the pressure of helium gas, measured from its equilibrium value, is given by δp = 2.9 × 10−5 cos (6.20x − 3 000t), where x and t have units m and s, and δp is measured in n/m2. determine the wavelength (in m) of the wave.

The wavelength of this wave is 1.01 meters.

Explanation:

The variation in the pressure of helium gas, measured from its equilibrium value, is given by :

..............(1)

The general equation is given by :

...........(2)

On comparing equation (1) and (2) :

Since,

So, the wavelength of this wave is 1.01 meters. Hence, this is the required solution.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
