<span>The answer is transformer. They utilize
electromagnetic induction to generate current. This is only possible in
alternating current due to the differential increase and decrease of electrical
current that induces changes in magnetic flux in the coil. This varies the
magnetic flux of the primary coil that generates current in the secondary coil.</span>
Gravitational Potential of an object with mass m, and height of h metre is :
Now, if the mass of object is 2100 kg, height of 18 m is placed in there, then it's gravitational potential energy is ~
It's an insulator because it's glass which means it stops the current
Well, for one, alcohol impairs someone's ability to perceive distance and see or think clearly. The severity of it depends on the drinker's size. Hope that helped a little.
