To begin with, we can use the formula that links frequency, wavelength and velocity.
Because you already have the wavelength and the frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
Therefore, 400 x 2.5 = 1000m/s.
Hope this helps :)

Answer:
Explanation:
V = Voltage = 230 V
I = Current = 1.8 A
= Temperature change =
t = Time taken = 2 minutes
m = Mass of liquid = 750 g
c = Specific heat capacity of the liquid
Energy required to heat the water is equal to the heat released due to current passing
The specific heat capacity of the liquid is
