An FM radio consists of a series RLC circuit with a 6.57 pF (peco – 10-12) capacitor. If a person is dialed into a station broad

faust18 [17]

Answer:

3.6 x 10⁻⁷ H

Explanation:

C = capacitance of the capacitor = 6.57 x 10⁻¹² F

L = inductance of the inductor = ?

f = frequency of broadcasting system = 103.9 MHz = 103.9 x 10⁶ Hz

frequency is given as

$f = \frac{1}{2\pi \sqrt{LC}}$

$103.6\times 10^{6} = \frac{1}{2(3.14)\sqrt{(6.57\times 10^{-12})L}}$

Inserting the values

L = 3.6 x 10⁻⁷ H

How many electrons are in an Sn+2 ion?

Veseljchak [2.6K]

Sn is Tin which has 50 atomic number

it means it has 50 electrons in its outer shells

+2 shows its valency

plus sign comes when electrons are removed from an atom

so here 2 electrons are removed from Sn atom

remaining electrons are 50-2

48 electrons

In deep space (no gravity), the bolt (arrow)

salantis [7]

t = 0.527 s

It accelerates for 0.527 s.

Explanation:

We use the formula:

v = u+at

Given:

v = 106 m/s

u = 0 (since no gravity)

$a=201 \mathrm{m} / \mathrm{s}^{2}$

So applying the formula,

v = u+at

106 = 0 + 201t

t = 106/201

t = 0.527 s
