Answer:
It increases.
When the frequency of electromagnetic waves increases, the wavelengths also increase because the frequency sends power to the wavelengths.
The answer would be C. charge because the protons, which are positively charged particles, and the electrons, negatively charged particles, balance each other out and the atom becomes of a neutral charge (or no charge)
When ice melts, the physicals state changes from solid to liquid. The energy or the heat required (q) required to change a unit mass (m) of a substance from solid to liquid is known as the enthalpy or heat of fusion (ΔHf). The variables; q, m and ΔHf are related as:
q = m * ΔHf
the mass of ice m = 65 g
the heat of fusion of water at 0C = ΔHf = 334 J/g
Therefore: q = 65 g * 334 J/g = 21710 J
Now:
4.184 J = 1 cal
which implies that: 21710 J = 1 cal * 21710 J/4.184 J = 5188.8 cal
Hence the heat required is 5188.8 cal or 5.2 Kcal (approx)
