Answer:</h2>
An LC circuits if formed by an inductor and a capacitor. The charge on the capacitor and the current through the inductor both vary sinusoidally with time. Also, energy is transferred between magnetic energy in the inductor and electrical energy in the capacitor. But <em>what happens with the frequency if the inductance is quadrupled? </em>that is, if initially the inductance is 
and the frecuency 
if now 
What will the frequency be? Well, we know that the frequency, inductance and capacitance are related as:
and this equals 2000Hz. If now L is quadrupled:
<em>Finally, if L is quadrupled the frequency is half the original frequency and equals 1000Hz</em>
The work function has the formula
E = h v
where
E is the energy
h is the constant
v is the frequency
Since the given is wavelength, we use the relationship between frequency and wavelength
v = c / λ
where
c is the speed of light
<span>λ is the wavelength
</span>
So.
E = h c / <span>λ
h = E</span><span>λ / c = 1.25 eV (475x10-9m) / (3x10^8 m/s)
h = 1.9792 x 10^-15
The work function is:
E = 1.9792 x 10-15 v

<span>Well, ice is NOT more compressed than water.
Ice molecules do NOT have more charge than water molecules.
Water does NOT have a lower temperature than ice.
But water molecules DO move around more easily than ice molecules</span>
Answer:
160N/m
Explanation:
According to Hooke's law which states that the extension of an elastic material is directly proportional to the applied force provided that the elastic limit is not exceeded. Mathematically,
F = ke where
F is the applied force
k is the spring constant
e is the extension
From the formula k = F/e
Since the body accelerates when the block is released, F = ma according to Newton's second law of motion.
The spring constant k = ma/e where
m is the mass of the block = 0.4kg
a is the acceleration = 8.0m/s²
e is the extension of the spring = 2.0cm = 0.02m
K = 0.4×8/0.02
K = 3.2/0.02
K = 160N/m
The spring constant of the spring is therefore 160N/m
