Answer
The capacitor should be connected in parallel as parallel connection gives the arithmetic sum of capacitance which will give a corresponding sum of energy while capacitors in series gives the sum of the reciprocal if the individual capacitance
Answer:
Explanation:
Given





R for Helium 

mass of gas 


Similarly
can be found


Work done 


Since it is a polytropic Process
therefore 






From Energy balance
Neglecting kinetic and Potential Energy change

Change in Internal Energy 




i.e. Heat is being removed
Answer:
68 readings.
Explanation:
We need to take this problem as a statistic problem where the normal distribution table help us.
We can start considerating that X is the temperature of the solution, then



For a confidence level of 90% our
is 1.645
Therefore,

Substituting for
and re-arrange for n, we have that n is equal to




We need to make 68 readings for have a probability of 90% and our average is within 
Answer:
Transmission
Explanation:
It’s the passage of electromagnetic waves through a medium.
