2.7a 110 v heating element in a stove can boil a standard-size pot of water in 1.2 minutes, consuming a total of 136 kjof energy. determine the resistance of the heating element andthe current flowing through it.

Resistance of the heating element: 6.4 ohm

Current flow:17.17 amperes

Explanation:

First we need to convert from Joules to Watts, in order to do that we need the time in seconds:

Then apply the formula:

Clearing watts from the equation:

Then, we know the input voltaje is 110V, and Watts= Voltage* Current.

Finally Voltaje over Current= Resistance, from ohm's law

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.

i don't understand. explain it clearly
