Answer:
Explanation:
Notice that in the periodic table, the atom with 13 protons is the aluminum, whose chemical symbol is; .
When it is neutral (same number of protons than orbital electrons) there is nothing particular added to its symbol, but when it has lost 3 electrons, now the charges of the nucleus compared to such of the orbits are not in balance any more, because there are three positive charges unpaired. Now it is an ion, and the way to represent it is to add on the upper right of its symbol, a a "3+" representing the charge imbalance:
Option c) 1.5 V
Explanation:
<em>As the circuit is build in series first we will find the current passing through the complete circuit. Current stays the same in each element is the series cirucuit, however, the voltage is different.</em>
Voltage is given by the following formula:
V = IR
<em>Because we have to find current through whole circuit, we will first find resistance of the whole circuit.</em>
Equivalent Resistance R(eq): R1 + R2 = 60 + 60 = 120 ohm
Current passing through whole circuit be:
= 0.025
Now we will find out the voltage between C and D:
Current stays the same in series circuit: I = 0.025 c
Resistance between C and D is, R = 60 ohm
Voltage becomes, V = IR = 0.025 * 60 = 1.5 V
To solve this problem it is necessary to apply the concepts related to Malus' law. Malus' law indicates that the intensity of a linearly polarized ray of light that passes through a perfect analyzer with a vertical optical axis is equivalent to:
Indicates the intensity of the light before passing through the Polarizer,
I = The resulting intensity, and
= Indicates the angle between the axis of the analyzer and the polarization axis of the incident light.
There is 3 polarizer, then
For the exit of the first polarizer we have that the intensity is,
For the third polarizer then we have,
Replacing with the first equation,
Therefore the transmitted intensity now is of the initial intensity.
Explanation:
It is given that,
Magnitude of magnetic field, B = 0.35 T
Side of square, a = 0.2
Area of square,
Angle between field and normal of the surface is 35 degrees. So, the angle between the magnetic field and area is,
We need to find the flux through the loop. Magnetic flux is given by :
or
Hence, this is the required solution.
