Answer:
Explanation:
Let the potential difference remains same. So, by insertion the dielectric, the capacitance
C' = KCo
As V remain same, so Q' = KQo
Energy, U' = 1/2 C'V² = KCo
Electric field, E' = E/ K
Where, k be the dielectric constant.
Thus, V remains same
Energy increases
C increases
E decreases
Q increases.
Answer:
0.57 m
Explanation:
The wavelength of a wave is given by:
where
is the wavelength
v is the speed of the wave
f is its frequency
In this problem, we have
v = 343 m/s is the speed of a sound wave through air
is the frequency of the wave
Substituting into the formula, we find the wavelength
