Answer:
down here.
Explanation:
When the two samples of water (hot water and cold water) are put in contact, thermal energy is transferred from the hot water to the cold water. This occurs because heat always flows from a hotter object to a colder object. The heat is transferred by collision between the molecules: the molecules of the hot water have on average more kinetic energy than the molecules of cold water, so when they collide to each other, the molecules of hot water transfer energy to the molecules of cold water. As a result, the kinetic energy of the molecules of cold water increases, and therefore the temperature of the cold water increases, while the temperature of the hot water decreases. This process lasts until the molecules of the two samples have same average kinetic energy: when this occurs, the two samples have.
gravity, fluid friction, and i think two more i just cant remember them
Answer:
L = 6 cm
Explanation:
Second overtone of the wire is same as third harmonic
so its frequency is given as
![f = \frac{3}{2L}\sqrt{\frac{T}{\mu}}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B3%7D%7B2L%7D%5Csqrt%7B%5Cfrac%7BT%7D%7B%5Cmu%7D%7D)
here we know that
![\mu = \frac{M}{L}](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%5Cfrac%7BM%7D%7BL%7D)
![\mu = \frac{7.25 \times 10^{-3}}{0.62}](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%5Cfrac%7B7.25%20%5Ctimes%2010%5E%7B-3%7D%7D%7B0.62%7D)
![\mu = 0.0117 kg/m](https://tex.z-dn.net/?f=%5Cmu%20%3D%200.0117%20kg%2Fm)
now we have
![f = \frac{3}{2\times 0.62}\sqrt{\frac{3910}{0.0117}}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7B3%7D%7B2%5Ctimes%200.62%7D%5Csqrt%7B%5Cfrac%7B3910%7D%7B0.0117%7D%7D)
![f = 1398.6 Hz](https://tex.z-dn.net/?f=f%20%3D%201398.6%20Hz)
Now fundamental frequency of sound in a pipe is given as
![f = \frac{v}{4L}](https://tex.z-dn.net/?f=f%20%3D%20%5Cfrac%7Bv%7D%7B4L%7D)
![1398.6 = \frac{340}{4L}](https://tex.z-dn.net/?f=1398.6%20%3D%20%5Cfrac%7B340%7D%7B4L%7D)
![L = 0.06 m](https://tex.z-dn.net/?f=L%20%3D%200.06%20m)
![L = 6 cm](https://tex.z-dn.net/?f=L%20%3D%206%20cm)
two or more materials mixed or stirred together. dissolve: the process of a material mixing with a liquid in a special way. ... sugar) as possible has dissolved in a liquid (such as coffee), and any additional solid material sits on the bottom.
