There
are five layers of the atmosphere and these are; troposphere, stratosphere,
mesosphere, thermosphere and exosphere. The first layer, troposphere, is where
we are able to do most of our activities. This is where we can see the formation
of clouds, the production of rain, hail, snow and other weather phenomenon.
Also, this layer is where the greatest amount of air pressure because most of
the molecules of air are in this area. Like us, air has also mass and the
pressure is brought down by the earth’s gravity causing an increase in weight
exerted on you as you descend lower into the atmosphere. So, as you enter into
the other layers of atmosphere above the troposphere, the air pressure starts
to decrease. <span>Below the atmosphere
is the hydrosphere. This is where all liquid forms are located. And since the
seawater has a greater mass than air, it has the greatest pressure. </span>
Answer:
In a voltaic cell, current is produced by connecting an oxidation reaction half cell to a reduction reaction half cell in an electrolyte solution. Oxidation and reduction reactions (redox reactions) are chemical reactions involving a transfer of electrons from one atom in the reaction to another. When two different oxidation or reduction reactions are connected electrically by connecting the cathode to the anode, a current is formed. The direction depends on the type of reaction taking place at the terminal.
The first step would be to determine metals to be used as the cathode and the anode.
The gravitational force of the planet pulling on the sun is equal to the gravitational force of the sun pulling on the planet
Explanation:
We can solve this problem by applying Newton's third law, which states that:
<em>"When an object A exerts a force (called </em><em>action</em><em>) on an object B, then object B exerts an equal and opposite force (called </em><em>reaction</em><em>) on object A"</em>
In this problem, we can identify:
- The sun as object A
- The planet as object B
By applying Newton's third law, we can state that:
- The action is the gravitational force exerted by the sun on the planet
- The reaction is the gravitational force exerted by the planet on the sun
According to the law, the two forces are equal in magnitude and opposite in direction: so, we can conclude that
The gravitational force of the planet pulling on the sun is equal to the gravitational force of the sun pulling on the planet
