The appropriate term is latent heat. This energy is released as the water changes state from a gas to liquid....a liquid to solid etc. the latent heat is either absorbed or given off by the water as it changes its physical state. Latent heat of fusion is associated with freezing a liquid or melting a solid.
Out of the processes of the water cycle, namely evaporation, precipitation, condensation, transpiration, storage, and flow, the condensation part of the water cycle releases energy. People might argue that it is evaporation, but actually during evaporation, what happens to energy is that it is taken in which makes the environment cooler. During the condensation, it is needed for water vapor to release the energy from evaporation which in return makes the environment warmer. As to the other three, transpiration, storage, flow, there is no known releasing of energy involved.
Answer:
Explanation:
Area of crossection, A = 7.80 cm²
Initial magnetic field, B = 0.5 T
Final magnetic field, B' = 3.3 T
Time, t = 1 s
resistance of the coil, R = 1.2 ohm
The induced emf is given by
where, Ф is the rate of change of magnetic flux.
e = 7.80 x 10^-4 x (3.3 - 0.5) / 1
e = 2.184 mV
i = e/R
i = 2.184/1.2
i = 1.82 mA
6 Ampere
<em><u>the formula is </u></em>

<em><u>the formula is v = Ir hence formula of current is v/r </u></em>
<em><u>the formula is v = Ir hence formula of current is v/r so, I = 120/20</u></em>
<em><u>the formula is v = Ir hence formula of current is v/r so, I = 120/20I = 6 ampere</u></em>
