Answer:
Water gains energy during evaporation and releases it during condensation in the atmosphere
Explanation:
In the water cycle, heat energy is gained or lost by water as it undergoes various processes in the cycle.
In evaporation, water molecules gains energy because the molecules of water vibrate faster and become more energetic. Hence they are able to escape into the atmosphere from the surface of the liquid.
In condensation, the molecules of gaseous water looses energy and becomes liquid.
Hence, water gains energy during evaporation and releases it during condensation in the atmosphere.
Answer:
58515.9 m/s
Explanation:
We are given that
![d_1=4.7\times 10^{10} m](https://tex.z-dn.net/?f=d_1%3D4.7%5Ctimes%2010%5E%7B10%7D%20m)
![v_i=9.5\times 10^4 m/s](https://tex.z-dn.net/?f=v_i%3D9.5%5Ctimes%2010%5E4%20m%2Fs)
![d_2=6\times 10^{12} m](https://tex.z-dn.net/?f=d_2%3D6%5Ctimes%2010%5E%7B12%7D%20m)
We have to find the speed (vf).
Work done by surrounding particles=W=0 Therefore, initial energy is equal to final energy.

(please mark brainliest if correct/helped you <3)
The correct answer among all the other choices is "None of the above." <span>Electrons carry energy from a battery to a light bulb. The electron's potential energy will be converted into light energy. </span>Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
