Its frequency because you already found out its speed & period
Given:
Water, 1.5kg at boiling point
Required:
Heat required to vaporize at boiling
point
Solution:
Water at boiling point is at
100degrees Celsius
Changing it into Kelvin, just dd
273 to 100 = 373 K
H
= mCpT
H
= (1.5kg)(4.184kJ/kg-K)(373K)
<span>H =
2340.9kJ</span>
The answer is A 0 degrees is the freezing point of water

<em>Another key factor that determines a star's colour is its temperature. As stars become hotter, the overall radiated energy increases, and the peak of the curve changes to shorter wavelengths. To put it another way, when a star heats up, the light it produces moves toward the blue end of the spectrum.</em>
