The Formula Bar is where data or formulas you enter into a worksheet appear for the active cell. The Formula Bar can also be used to edit data or formula in the active cell. The active cell displays the results of its formula while we see the formula itself in the Formula Bar.

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:
a) 6.4 kJ
b) 43.4 kJ
Explanation:
a)
= Heat absorbed = 37 kJ
= Coefficient of performance = 5.8
= Work done
Heat absorbed is given as
=
37 = (5.8)
= 6.4 kJ
b)
= work per cycle required
= +
= 37 + 6.4
= 43.4 kJ
Answer:
This is because of Van der Waals forces
Explanation:
The ideal gas laws do not take into account the inter molecular forces that exist between the molecules of the gas. However, Van der Waals discovery showed that some weak forces of attraction exist between the molecules of the gas and at high pressures, their presence can affect the volume of the gas, making it larger than what is predicted by the ideal gas law.
These forces of attraction between the gas molecules is called Van der Waals forces.
