Answer:

Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. Liquids are not packed as tightly.Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound.Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. A vibrating string can create longitudinal waves as depicted in the animation below.

The mass defect for the formation of lithium-6 is 0.0343 g/mol. The binding energy for lithium-6 nuclei is ________ kJ/mol. Ente

Sholpan [36]

Answer: The binding energy for lithium-6 nuclei is 3.09 E+11

Explanation:

Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.

This energy is calculated by using Einstein's equation, which is:

$E=\Delta mc^2$

where,

E = Binding energy of the atom

$Delta m$ = Mass defect = 0.0343g/mol = $0.0343\times 10^{-3}kg/mol$ (Conversion factor: $1kg=10^3g$ )

c = speed of light = $3\times 10^8m/s$

Putting values in above equation, we get:

$E=0.0343\times 10^{-3}kg/mol\times (3\times 10^8m/s)^2$

$E=3.09\times 10^{14}J/mol=3.09\times 10^{11}kJ/mol$ (Conversion factor: $1kJ=10^3J$ )

Hence, the binding energy for lithium-6 nuclei is 3.09 E+11

LOUI How does the foaming helps in cleaning of the dirt particles?

Aloiza [94]

Answer:

The attraction of the soil to the inside of the surfactant micelle helps loosen the soil from its surface. Once the soil lifts off the surface, it becomes suspended in the water in the micelle. This suspension is also known as emulsification of one liquid into another.
