A1.5m wire carries a 8 a current when a potential difference of 96 v is applied. what is the resistance of the wire? answer and units? !

I dont know why the length is given unless there is a second part to the problem, but Resistance = Potential difference / Current.

So:

V= 96 volts

I= 8 amps

R = 96/8

R= 12 ohms

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
