Your fill-ins for the first three lines of the table are correct.  Good work.

You have all the same answers for the last 2 lines of the table, like
it makes no difference to anything whether S2 is open or closed. 
That's not correct. It does make a difference.  If S2 is closed, then
the current would much rather go through S2 than through the bulbs
C and D because it's so much easier, and that's exactly what it does.
When S2 is closed, bulbs C and D are off. 

But I'll say again:  Except for those two middle boxes on the bottom line
of the table, everything else is correct.  That's 12 correct fill-ins for you,
and only 2 incorrect ones.  That's a score of 86% !  After posting so many
of these on Brainly this afternoon, doesn't it feel great to do your own work
for a change, and get it almost all correct ?

andreev551 [17]
While refrigerant 410a is a near azeotropic refrigerant, it is still best when charging to remove the r-410a as a liquid from the storage cylinder.
Azeotrope means a constant boiling mixture. it is a mixture of two or more liquids,by simple distillation whose proportions cannot be changed. A mixture behaving purely is azeotropic and the mixture which behave differently is called non-azeotropic.

Answer:

  • <u><em>1,230N</em></u>

Explanation:

<u>1. Name of the variables:</u>

   f:frequency\\\\ \omega:angular\text{ }speed\\\\ a_c:centripetal\text{ }acceleration\\\\ F_c:centripetal\text{ }force\\ \\ m:mass\\ \\ d:diameter\\ \\ r:radius\\ \\ g:gravitational\text{ }acceleration

<u>2. Formulae:</u>

         f=\dfrac{number\text{ }of\text{ }revolutions}{time}

          \omega=2\pi f

          a_c=\omega^2 r

           F_c=m\times a_c

<u>3. Solution (calculations)</u>

       f=\dfrac{1}{1.65s}=0.\overline{60}s^{-1}

       \omega=2\pi\times0.\overline{60}\approx 3.808rad/s

      a_c=(3.808rad/s)^2\times (3.74/2m)=27.12m/s^2

      F_c=45.2kg\times27.12m/s^2=1,225.67N\approx 1,230N
