Definitely the first: the water molecule is polar. :)
Answer:
Metal - smallest band gap energy
insulators - large band gap energies
semiconductor - Band gap of intermediate energies
superconductor cooper pair theory is applied for calculating gap energies.
Explanation:
Metal - smallest band gap energy
it is due to the fact that valence and conduction bond in metal are in overlapped conditioned. Therefore showing zero gap energies
insulators - large band gap energies
insulator has high band gap
semiconductor - Band gap of intermediate energies
semi conductor has gap of intermediate range
while for superconductor cooper pair theory is applied for calculating gap energies.
Answer:


Part b)

Explanation:
Part a)
tension in the wire at any distance "y" from the bottom end of the wire is due to the weight of the suspended part of the wire given by the equation

So here we will have speed of the wave is given as

now we have


Part b)
now the time taken by the wave to reach the top is given as

Answer:
a) = 10.22 rad/s
b) = 0.35 m
Explanation:
Given
Mass of the particle, m = 1.1 kg
Force constant of the spring, k = 115 N/m
Distance at which the mass is released, d = 0.35 m
According to the differential equation of s Simple Harmonic Motion,
ω² = k / m, where
ω = angular frequency in rad/s
k = force constant in N/m
m = mass in kg
So,
ω² = 115 / 1.1
ω² = 104.55
ω = √104.55
ω = 10.22 rad/s
If y(0) = -0.35 m and we want our A to be positive, then suffice to say,
The value of coefficient A in meters is 0.35 m
