Answer:

Its P path describes the change of state i.e from solid to liquid.

What is solid ?

"A solid is that state of matter which has a fixed shape, mass, and volume. It suffers very small changes in volume by changing the temperature. It can not be compressed, e.g. — Sand, Wood, Copper, Ice, etc."

What is liquid ?

"A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. The term liquid is also used in reference to the state, or condition, of matter having this property."

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

To find the mass defect for uranium-238 several calculations must be made. Which is the calculation that should be made first? A

BaLLatris [955]

mass number of uranium 238 is sum of number of proton and neutrons in it

While atomic number is just number of protons

So total number of protons in it = 92

total number of neutrons in it = 238 - 92 = 146

mass of proton = 1.0073 amu

mass of neutron = 1.0087 amu

now for the calculation of mass of nuclei is given as

$M = zm_p + (A-z)m_n$

$M = 92(1.0073) + 146(1.0087)$

so option B is correct
