Answer:
The combination of elements most likely to comprise the circuit are resistor, inductor and capacitor
Explanation:
The impedance of an LCR circuit shown as
Z = √R² + (X↓l - X↓c)²
Z = √R² + (2π∨L - 1/2π∨c)²
Variation of Z with respect to υ is shown in the figure.
As υ increases, Z decreases and so the current increases.
At υ = υ↓r
Z is minimum, current is maximum. Beyond
υ = υ↓r
Z increases and so current decreases.
so the combination of circuit elements that is most suitable to comprise
the circuit is R, L and C.

g Generally the accepted value of acceleration due to gravity is 9.801 
as per the question the acceleration due to gravity is found to be 9.42 in an experiment performed.
the difference between the ideal and observed value is 0.381.
hence the error is -
=3.88735 percent
the error is not so high,so it can be accepted.
now we have to know why this occurs-the equation of time period of the simple pendulum is give as-![T=2\pi\sqrt[2]{l/g}](https://tex.z-dn.net/?f=T%3D2%5Cpi%5Csqrt%5B2%5D%7Bl%2Fg%7D)
As the experiment is done under air resistance,so it will affect to the time period.hence the time period will be more which in turn decreases the value of g.
if this experiment is done in a environment of zero air resistance,we will get the value of g which must be approximately equal to 9.801
The sun's source of energy is know as nuclear fusion (means to fuse) this process has a small nuclei atoms that join together to form a large nucleus. The result of this process is released energy. The fusion of hydrogen into helium in the sun makes a large amount of energy and this is known as the sun's energy source.
The theories that scientist proposed about the source of the sun's energy was that the sun burned fuel to generate its energy and that gravity was causing the sun to shrink slowly and have its energy released. Also both of these theories were disproved.
