Static charge occurs when there is an imbalance of positively and negatively charged atoms, so this one should be the last option that it involves ions as well.
Hope this helps :)
Scientists could explore Europa’s oceans by using potent technologically advanced telescopes capable of deciphering the content beneath the ice crust.
<h3>What are potent technologically advanced telescopes?</h3>
The latest technologically advanced telescopes are potent optical devices that allow us to discover the presence of certain compounds not only in the atmosphere of other planets in the solar system but also the content on the surface (e.g, the water content).
These telescopes contain curved mirrors that gather and focus different spectra of light from the sky such as the Webb telescope which was launched by NASA in the final of 2021.
Therefore, with this data, we can see that technologically advanced telescopes are potent optical instruments that can be used to observe the presence of different compounds including water on the surface of a planet or its satellites such as in the case of Europe which is a satellite of Jupiter.

The correct option is D.
During hurricane, the most important thing is to get people out to safety in order to save their lives. Training the community about safety evacuation route is by far the better idea because it provide immediate safety from the natural hazard. The second idea is not a good one at all, because if food are stocked in every house in the community, the food will be destroyed alongside other things during the hurricane.
Answer:
Let the mass of the book be "m", acceleration due to gravity be "g", velocity be "v" and height be "h".
Now if we are holding a book at a certain height (h), <em><u>the potential energy will be maximum which is equal to mass× acceleration due to gravity× height (= mgh)</u>.</em>
(Remember: kinetic energy =0)
Now we consider that the book is dropped, in this case a force will act downward towards the centre of the earth, <em><u>Force= mass× acceleration due to gravity (F=mg)</u></em>. It is equal to the weight of the book.
While the book is falling, the potential energy stored in the book converts into kinetic energy and strikes the floor with <em><u>the maximum kinetic energy= (1/2)×mass×velocity² (=1/2mv²)</u>.</em>
(Remember: kinetic energy=0)
Due to this process the whole energy is conserved.
As the potential energy decreases kinetic energy increases.
Because each earthquake can go in different places which the wind moves different and then the earth moves different.
