Answer:
Infrasound vs. Ultrasound: Infrasound is sound that is below the lower limit of human hearing, below 20 Hz, and ultrasound is above the upper limit of human hearing, above 20,000 Hz. Individuals use infrasound - this recurrence run for checking seismic tremors and volcanoes, graphing rock and oil developments underneath the earth. Infrasound is described by a capacity to get around hindrances with little scattering.
For instance, a few creatures, for example, whales, elephants and giraffes convey utilizing infrasound over significant distances. Torrential slides, volcanoes, seismic tremors, sea waves, water falls and meteors produce infrasonic waves. Symptomatic ultrasound, additionally called sonography or demonstrative clinical sonography, is an imaging technique that utilizes high-recurrence sound waves to create pictures of structures inside your body. The pictures can give important data to diagnosing and treating an assortment of ailments and conditions.

B. Effective length of the tube.
Explanation;
- Most wind instruments are of either the open-open tube or the open closed tube type. Open ends of the tubes makes contact with the outside, atmospheric air.
- At an open end, when the air is disturbed in the wind instruments, the air vibrates with a variety of frequencies, however the frequencies that correspond to the natural frequencies will persist.
- Effective Length of the tube is responsible for determining the frequency of vibration of the air column in the pool with in a wind instrument.

V = Volume of sample of gas = 1.00 L = 0.001 m³
T = temperature of the gas = 25.0 ⁰C = 25 + 273 = 298 K
P = pressure = 1.00 atm = 101325 Pa
n = number of moles of gas
using ideal gas equation
PV = n RT
101325 (0.001) = n (8.314) (298)
n = 0.041
n₁ = number of moles of helium
n₂ = number of moles of neon
m₁ = mass of helium = n₁ (4) = 4 n₁
m₂ = mass of neon = n₂ (20.2) = 20.2 n₂
given that :
m₁ = m₂
4 n₁ = 20.2 n₂
n₁ = 5.05 n₂
also
n₁ + n₂ = n
5.05 n₂ + n₂ = 0.041
n₂ = 0.0068
mole fraction of neon is given as
mole fraction = n₂ /n = 0.0068/0.041 = 0.166
P₂ = partial pressure of neon = (mole fraction) P
P₂ = (0.166) (1)
P₂ = 0.166 atm
The partial pressure of the neon is 0.16 atm.
Explanation:
A 1.00 l sample of a gas at 25.0◦c and 1.00 atm contains 50.0 % helium and 50.0 % neon by mass. what is the partial pressure of the neon. express your answer in atmospheres.
The partial pressure is the notional pressure of constituent gas if it is occupied alone by the entire volume of the original mixture at the same temperature.
50.0 % helium and 50.0 % neon by mass.
Mass of the gases =
By using ideal gas equation we get:
where total number of moles of gases
Then we can find the mass and mole of gases
The gas molar volume is the volume of one mole of the gas at a given temperature and pressure.
Mass of helium gas =
Moles of helium gas
Mass of neon gas
Moles of neon gas
Partial pressure of the neon gas:
Therefore the partial pressure of the neon gas is 0.16 atm.

Using a cathode ray tube, Thomson confirmed that atoms are made of particles that have a negative charge., therefore the correct answer is option B
What are atomic models?
There are some models that are used to explain the arrangements of subatomic particles inside the atom based on the atomic theory of atom are known as the atomic models.
J.J. Thomson discovered using cathode ray tubes that something emits from the negative plate (referred to as the cathode) and travels towards the positive plate (referred to as the anode), and that when zinc sulfide (also known as a phosphor) coating is applied to the perforated anode, it exhibits green fluorescence at a specific pressure and temperature values.
Thus,by using a cathode ray tube, Thomson confirmed that atoms are made of particles that have a negative charge., therefore the correct answer is option B

Option (B) is correct .i.e. atoms are made of particles that have negative charge.
Further explanation:
Using cathode ray tube, J.J Thomson found that something emits from the negative plate (called as cathode) and goes towards the positive plate (called as anode), and on applying zinc sulfide (also called phosphor) coating on the perforated anode, it shows green fluorescence at some particular values of pressure and temperature.
William Crookes called them the cathode rays as were originated from cathode. Further, Atoms are overall neutral having equal amounts of positive and negative charge as he explained in his plum pudding model.
Although, electrons in atoms have varying energy but this was not confirmed by J.J. Thomson, also electrons can’t be inside nucleus because this would make atoms very unstable.
Some of the properties of those cathode rays are as follows:
(1). They are made up of material particles (they made the light wheels rotate that come in their path).
(2). The green fluorescence was also observed when he putted two more plates perpendicular to the earlier path and the rays followed a curved path towards the new anode.
(3). They has an ionizing property (they ionizes the gas present in the cathode ray tube, through which they pass).
Thus, Option (B) is correct because the cathode rays are emitted from the metallic plate which’s atoms have particles having negative charge.
