Answer:
A symbol and a model are both examples of a representation because they are presented in place of the real thing.
Explanation:
A symbol is a sign, a letter, mark, token, figure, or image used to stand in place of an object, function, or process. For example, co2 is used in Chemistry to represent carbon dioxide. There are many symbols representing other objects or meanings. Mathematically, we can state that "a" equals 40. "a" is a symbol representing the numerical value "40." Similarly, a model is a representation of a structure or a person on a smaller scale. For example, Architects produce models of buildings and other projects that they design.
Given Information:
Amplitude of the electric field = E = 570 N/C
Speed of light = c = 3.0x10⁸ m/s
Required Information:
Amplitude of the magnetic field = ?
Answer:
Amplitude of the magnetic field = 1.90x10⁻⁶ T
Explanation:
The relation between the amplitude of the electric field and magnetic field is given by
B = E/c
Where c is the speed of light
B = 570/3.0x10⁸
B = 1.90x10⁻⁶ T
Therefore, the amplitude of magnetic field is 1.90x10⁻⁶ T
The best answer would be A
The correct answer for the question that is being presented above is this one: "an air mass that formed over land. it is cold and dry." When describing a maritime polar air mass, you might say it formed over land and is cold and dry. It's temperature c<span>an range from around freezing to near 20 degrees Celsius</span>
If<span> a neutral </span>object loses<span> some </span>electrons<span>, </span>then<span> it will possess more protons</span>
