Answer:
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
Explanation:
The Law of Definite Proportions/Proust's Law
<h3>
<u>Two </u><u>device</u><u> </u><u>that </u><u>are </u><u>using</u><u> </u><u>spinning</u></h3>
→ <u>Takli</u>
- Takli is a small support style spindle. Takli is a perfect tool for spinning cotton, and this are used too to spin fibers, cotton, cashmere, and silk etc. Takli is known as handspindle. And it is the simplest device for spinning.
→ <u>Charkha</u>
- Charkha is a device for spinning thread or yarn from fibers etc. This are known as spinning wheel.
<h2>HAVE A NICE DAY!</h2>
Hydrazine has a higher boiling point than water because hydrazine exhibits a stronger intermolecular forces than water. Although both compounds exhibit hydrogen bonding which is a strong intermolecular force resulting to a high boiling point, hydrogen bonding is stronger in hydrazine. This is because in a hydrazine molecule, there are two atoms of nitrogen available for hydrogen bonding as compared to water which has only 1 oxygen atom for hydrogen bonding.
It depends on mass and velocity.
In this case as the ice is solid its particles are stationary that it have zero velocity hence its kinetic energy is too zero.
