First law is Conservation of Energy
Second is that entropy of an isolated system will always increase with time.
Entropy is the change of disorder through time. The best statement which relates to the 2nd law is C. Thermal energy flows from areas of higher to lower temperature
D is the answer
I hope it helps!
Well, before we discuss that, I think we have to carefully understand
and agree on something. We have to be very clear about what we
mean by 'weight' ... is it what you feel, or is it the product of
(your mass) x (the acceleration of gravity where you are).
If you're on a space ship, then any time your engine is not burning,
you feel weightless. It doesn't matter where you are, or what body
you may be near. If you're not doing a burn, and the only force on
you is the force of gravity, then you don't feel any weight at all.
But of we say that your 'weight' is the product of
(your mass) times (the acceleration of gravity where you are),
then it depends on where you are, and whether you're close to
the Earth or closer to the moon. You may not feel it, but you're
going to have weight, and it's going to change during your trip
in space.
You know that the force of gravity depends on how far you are
from the body that's attracting you.
-- As you travel from the Earth to the moon, gravity will pull you
less and less toward Earth, and more and more toward the moon.
-- Your weight will get less and less, until you reach the point
in space where the gravitational attractions are equal in both
directions. That's about 24,000 miles before you reach the
moon ... about 90% of the way there. At that point, your weight
is really zero, because the pull toward the Earth and the pull toward
the moon are equal.
-- From there, the rest of the way to the moon, your weight will
start to grow again. It begins at zero at the 'magic point', and it
grows and grows until you reach the moon's surface. When
you're there, your weight has grown to about 1/6 of what you
weigh on Earth, and it won't get any bigger. If you weigh
120 pounds on Earth, then you weigh about 19.86 pounds on
the moon ... PLUS your space suit, boots, heater/air conditioner,
oxygen tank, radiation shielding, radio, and all the other stuff that
you need to survive on the moon for a few hours.

Answer:
Part a)
Part b)
in this case the charge on the capacitor will become zero
Part c)
Part d)
Explanation:
As we know that first capacitor is charged with the battery and then it is connected to the inductor
So here we will have
Part a)
now since the total energy of capacitor is converted into the energy of inductor
so by energy conservation we can say
so maximum current is given as
Part b)
When current is maximum then whole energy of capacitor is converted into magnetic energy of inductor
So in this case the charge on the capacitor will become zero
Part c)
Time period of oscillation of charge between the plates and inductor is given as
now capacitor gets discharged first time after 1/4 of total time period
Part d)
Since time period is T and capacitor gets discharged two times in one complete time period of the motion
so first it will discharges in T/4 time
then next T/4 it will get charged again
then next T/4 time it will again discharged
so total time taken
