Releasing any species into an environment it's not adapted to, or native to is dangerous because the species lacks the necessary adaptations to survive in the environment.
In the example of the frog, releasing it into a grassland would be a bad idea because the frog needs not only a "moist" area to thrive but it needs places to hide and plenty of insects to feed off of. Also, for reproduction it would need a pond, or some kind of water source!
I hope this is helpful!
<span>So when the charged insulator is placed near the uncharged metallic thing they both attract each other because there will be a distribution of charge between the insulator and uncharged object. This migration of charges happens regardless of their charge positive or negative.</span>
1.uniti m/s indicate it is in SI unit
2.It gives the distance covered by the object in unit time
3.Unit indicates that it velocity not other unit
4.In a problem if other units are other than SI unit you can convert it
5.For comparison purpose you should know the unit unless you can't or it may be wrong
i think so
