Answer:

In a discharging battery or galvanic cell (diagram at right), the anode is the negative terminal because it is where conventional current flows into the cell.

Explanation

In the lab. construct two half cells, one a zinc half cell and the other a copper half cell.

The zinc metal electrode will more readily ionise to Zn^2+  ion , then the copper metal.

This is because in the reactivity series zinc is more reactive metal.

Hence

connecting the two half cells, the zinc cell is put on the left and the copper half cell on the right.

Connect a wire and voltmeters between the electrodes, and a salt bridge between the two metal ion solutions.

Since the zinc is on the left and loses its electrons more readily the electrons flow from the electrode through the wire and voltmeter to the copper electrode.  So the electrons flow from r

left to right.

The conventional eq'n is

Zn|Zn^2+||Cu^2+|Cu

The electrons move into the copper electrode combine with copper solution to form more copper metal, which deposits on the copper electrode.

Answer:

Explanation:

Conventional current flows from cathode to anode. It is opposite to the direction of flow of electrons.

How does heat play a role in both the formation of folded mountains and the formation of volcanic mountains?
aliya0001 [1]
Among the most striking of geologic features are mountains, created by several types of tectonic forces, including collisions between continental masses. Mountains have long had an impact on the human psyche, for instance by virtue of their association with the divine in the Greek myths, the Bible<span>, and other religious or cultural traditions. One does not need to be a geologist to know what a mountain is; indeed there is no precise definition of mountain, though in most cases the distinction between a mountain and a hill is fairly obvious. On the other hand, the defining characteristics of a volcano are more apparent. Created by violent tectonic forces, a volcano usually is considered a mountain, and almost certainly is one after it erupts, pouring out molten rock and other substances from deep in the </span>earth<span>.

Please any one need help on this
Romashka [77]

-- The wavelength and the amplitude were described in my answer to your  previous question.

-- A "compression" is a place where the wave is <em>compressed</em>.  It's the darker section of the wave in the picture, where the wavelength is temporarily shorter, so several waves are all bunched up (compressed) in a small time.

-- A "rarefaction" is exactly the opposite of a "compression".  It's a place where the wave gets more "<em>rare</em>" ... the wavelength temporarily gets longer, so that several waves get stretched out, and there are fewer of them in some  period of time.  The arrow in the picture points to a rarefaction.

Find the required angular speed, ω, of an ultracentrifuge for the radial acceleration of a point 2.00 cm from the axis to equal
MAXImum [283]

Answer:

Angular velocity of an ultra centrifuge is 17146.42 rad/s.

Explanation:

Given that,

Acceleration of an ultra centrifuge, a=6\times 10^5\ g=6\times 10^5\times 9.8=5.88\times 10^6\ rad/s2

Distance from axis, r = 2 cm = 0.02 m

We need to find the angular speed. We know that the relation between angular speed and angular acceleration is given by :

a=r\omega^2\\\\\omega=\sqrt{\dfrac{a}{r}} \\\\\omega=\sqrt{\dfrac{5.88\times 10^6}{0.02}} \\\\\omega=17146.42\ rad/s

So, the angular velocity of an ultra centrifuge is 17146.42 rad/s.
