C. Positive or negative depending on the zone
Answer:
0.
Explanation:
To find the electrical force per unit area on each sheet we start defining our variables,



We find the electric field for each one, this formula is given by,

Substituting each value from the three charged sheets, we have



The electric field is



Force on each sheet is,


The total force is 0
I think it’s A

Answer:
The claim is false and violate the zeroth law of thermodynamics.
Explanation:
Zeroth law of thermodynamics refers to thermal equilibrium among elements. It states that elements which different temperatures will reach the same temperature at the endgame if they are close enough to interact each other. This temperaure is called <em>equilibrium temperature and it is always a intermediate value between the element with highest temperature and the element with the lowest one. So there is no way </em> a cup of cold coffee on a table can warm up to 80°C picking up energy from the surrounding air at 25°C because the cup can only reach a temperature closer to the surrounding air temperature which will be the equilimbrium temperature for that case.
