is correct?
Both resistors are equal to 5-ohms
Both resistors are greater than 5-ohms
Both resistors are less than 5-ohms
One of the resistances is greater than 5-ohms,
and one of the resistances is less than 5-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.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
