Answer:
(a) An electric iron works on the heating effect of electric current
(b) The heating effect of an electric current is the tendency for electric current to cause the temperature of the material through which it is flowing to rise due to the resistance of the material
The heating effect, 'E', is given by the formula, E = I²·R·t
Where;
I = The current flowing
R = The resistance of the material
t = The time the material takes to heat up
(c) The values showed by Pinki here is the value of care, concern and prevention, to prevent the harmful effect of the high heat on the skin of her daughter
Explanation:
Answer:
Heat is always the transfer of energy from an object at a higher temperature to an object at a lower temperature.
Explanation:
Answer:
The electric field is 
Explanation:
From the question we are told that
The peak magnitude of the magnetic field is 
Generally the peak magnitude of the electric field is mathematically represented as

Where c is the speed of light with value 
So


Answer:
Two Neutral
Explanation:
If; One postive, and one negative they would be attracked. >-<
If; one postive and the other was postive, (or vice versa) they would repel <->
they both have an electrical charge, and force.
Neutral's are Nueatral. they have to opisition or attraction= No electrical force.
