In a liquid with a density of 1500 kg/m3kg/m3 , longitudinal waves with a frequency of 360 HzHz are found to have a wavelength of 8.50 mm . Calculate the bulk modulus of the liquid.

30 Watts

Explanation:

We're provided with the following information:

Amount of Charge flown (Q) = 150 CPotential Difference (V) = 12 VTime (T) = 1 min

= 60 seconds

Current:

Current is the rate of flow of charge ,i. e., The amount of charge flowing "per second":

We have:

Charge flown (Q) = 150 CTime (T) = 60 seconds

Finding the current flown using the above mentioned formula:

=> I = 2.5 A

A(Amperes) is the SI unit of Current

Relation between Power, Voltage and Current:

We've a relation between Power, Current and Voltage, derived with the help of  "Joule's Law of Heating", and that is:

We can finally find Power, Since we have:

Current (I) = 2.5 AVoltage (V) = 12 V

=> P = 12 × 2.5

=> P = 30 W

W, Watts, is the Si unit of Power
