Answer:
The time rate of change of the electric field between the plates is 
Explanation:
From the question we are told that
The radius is 
The distance of separation is 
The current is 
Generally the electric field generated is mathematically represented as
Where 
is the permitivity of free space with a value
So the time rate of change of the electric field between the plates is mathematically represented as
But 
So
substituting values
The mass of a is smaller than the mass of b.
Options: A. Tech A. B. Tech B. C. Tech And B. C. None of the above.
Answer:Tech A and B
Explanation:A shift lever is the lever installed on the steering column or floor of a vehicle which allows the driver to shift gears or change gears, the manual valve position is controlled by shift lever as the shift lever moves the manual valve position changes. The

Answer:
C
Explanation:
To melt the alcohol
Heat needed = M . L = 2 . 25 = 50 kcal
To warm up the alcohol
Heat needed = M . sp. ht. . ∆t = 2 . 0.6 . 100 = 120 kcal
Total heat needed = 170 kcal
Assuming that 0.6 kcal/ kg / ˚C is the specific heat and that the answer is wanted in kcal ( a rather odd unit to be in use here.)
