Ligma is a disease heavily related to sawcon and lookatmah. Some symptoms are infatuation and a heavy desire to suck on lollipops. Please contact a doctor if you think you or someone else has Ligma, it's fatal.

How does the electric field intensity vary with the increase of distance of the point from the centre of a charged conducting sp

Nataly_w [17]

Answer:

(i) Electric field outside the shell:

For point r>R; draw a spherical gaussian surface of radius r.

Using gauss law, ∮E.ds=q0qend

Since E is perpendicular to gaussian surface, angle betwee E is 0.

Also E being constant, can be taken out of integral.

So, E(4πr2)=q0q

So, E=4πε01r2q

Radio Waves If your favorite FM radio station broadcasts at a frequency of 104.5 MHz, what is the wavelength of the station’s si

kompoz [17]

Answer:

The wavelength of the station’s signal is 2.9 meters

The energy of a photon of the station’s electromagnetic signal is $6.9\times10^{-26}J$

Explanation:

Wavelength $\lambda$ is inversely proprtional to frequency (f) and directly proportional to velocity of the wave (v).

$\lambda=\frac{v}{f}$ (1)

But electromagnetic waves as radio signals travel at speed of light so using this on (1):

$\lambda=\frac{c}{f}=\frac{3.0\times10^{8}}{104.5\times10^{6}}\approx2.9\,m$

Albert Einstein discovered that energy of electromagnetic waves was quantized in small discrete packages of energy called photons with energy:

$E=hf=(6.6\times10^{-34})(104.5\times10^{6})\approx6.9\times10^{-26}J$

with h the Planck's constant.

The lowest note on a grand piano has a frequency of 27.5 Hz. The entire string is 2.00 m long and has a mass of 440g . The vibra

ANEK [815]

Answer:

Tension, T = 2038.09 N

Explanation:

Given that,

Frequency of the lowest note on a grand piano, f = 27.5 Hz

Length of the string, l = 2 m

Mass of the string, m = 440 g = 0.44 kg

Length of the vibrating section of the string is, L = 1.75 m

The frequency of the vibrating string in terms of tension is given by :

$f=\dfrac{1}{2L}\sqrt{\dfrac{T}{\mu}}$

$\mu=\dfrac{m}{l}$

$\mu=\dfrac{0.44}{2}=0.22\ kg/m$

$T=4L^2f\mu$

$T=4\times (1.75)^2\times (27.5)^2 \times 0.22$

T = 2038.09 N

So, the tension in the string is 2038.09 N. Hence, this is the required solution.
