Anna notices that different types of clothing stick together when they are dried in an electric dryer. When the clothes are pull

ed apart, they make sparks and a crackling sound due to electric forces of attraction. How can Anna reduce the amount the clothing clings together in the dryer?
Add a substance to the wash that reduces the number of charges transferred.
Increase the temperature of the air in the dryer to weaken the electric forces.
Dry more clothes at the same time so that there is less room for electric forces.
Change the charges on the clothes by running the dryer at a faster speed.

A certain organ pipe, open at both ends, produces a fundamental frequency of 272 HzHz in air. Part A If the pipe is filled with
vladimir2022 [97]

Answer:

fundamental frequency in helium = 729.8 Hz

Explanation:

Fundamental frequency of an ope tube/pipe = v/2L

where v is velocity of sound in air = 340 m/s; λ is wave length of wave = 2L ; L  is length of  the pipe

To find the length of the pipe,

frequency  = velocity of sound / 2L

272 = 340 / 2 L

L = 0.625 m

If the pipe is filled with helium at the same temperature, the velocity of sound will change as well as the frequency of note produced since velocity is directly proportional to frequency of sound.

Also, the velocity of sound is inversely proportional to  square root of molar mass of gas; v ∝ 1/√m

v₁/v₂ = √m₂/m₁

v₁ = velocity of sound in air, v₂ = velocity of sound in helium, m₁ = molar mass of air, m₂ = molar mass of helium

340 / v = √4 / 28.8

v₂ = 340 / 0. 3727

v₂  =  912.26  m /s  

fundamental frequency in helium  = v₂ / 2L

fundamental frequency in helium = 912.26 / (2 x 0.625)

fundamental frequency in helium = 729.8 Hz

What type of water molecules have the greater tendency to condense to the liquid state from the gaseous state
ASHA 777 [7]

'The slower moving' type of water molecules have the greater tendency to condense to the liquid state from the gaseous state.

If the molecules speed up it means that energy has been added to the system. Eventually, therefore, the water would evaporate into steam (or water vapour) provided the energy was continued to be added to the system.

Vice versa if the molecules are slowed down then the water molecules in gas would condense and change their state from gas to liquid.

Condensation is the process where water vapour becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapour.

Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapour that it cannot hold any more water.

What happens if a chemical and physical change combine together?
sweet-ann [11.9K]

In a chemical change, a new substance is made, like when you burn a candle. In a physical change, no new substance is made, like when water turns to ice.
