Wavelength of the radio wave can only be identified if theirs an image. Radio wave doesn't have a fixed wavelength unless we are talking about the frequency than its 10^3

<span>The six noble gases that occur naturally are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).</span>
The sea level would rise by some 50 meters.
Explanation:
If the earth's temperature increases by 3 degrees the north and south pole would experience the ice melt at high speed.
The life will get difficult on the plains.
The extinction of some species will happen.
The sea level would rise by 50 meters. The increased sea level will cause depletion of habitat from plants and animals.
The floods will occur, land erosion, soil for agriculture land will get contaminated with the salt.
Calculate the heat gained by the water first.
q = mCpΔT
m = 20.0 g
Cp = 4.186 J/g°C
ΔT = T(final) - T(initial) = 15.0°C - 10.0°C = 5.0°C
q = (20.0)(4.186)(5.0) = 419 J
This is equal to the heat lost by the metal, so calculate Cp for the metal, given:
q = -419 J (negative because heat was lost)
m = 5.00 g
ΔT = 15.0°C - 100.0°C = -85.0°C (negative because the temperature decreased)
q = mCpΔT —> Solve for Cp —> Cp = q/mΔT
Cp = -419 / (5.00 • -85.0) = 0.986 J/g°C
