Answer:
1.
2.
Explanation:
Polarizes axis can create two possible angles with the vertical.
first we have to find the intensity of first polarizer
which is given as



For a smaller angle for the first polarizer:
According to Malus Law



taking square root on both sides



For a larger angle for the first polarizer:
According to Malus Law


taking square root on both sides



Answer:
The acceleration is 0.
Explanation:
The formula for acceleration is:
a = (v-u)/t
If v and u are equal, thus it would be 0 when subtracted, and anything divided by 0 is 0.
Hi, this sounds like a chemistry question:
If you wanted to separate sand from iron fillings for example, using tweezers would be a great tool to do this, depending on the size of the iron fillings.
Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules.
Titanium, Lead, Potassium, and Silicon are solids at normal temperature.
Mercury and bromine (Br) are the only liquid elements at standard pressure and temperature (Hg).
<h3>What are chemical elements?</h3>
A chemical element is a species of atoms, including the pure substance made entirely of that species, that have a specific number of protons in their nuclei. Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules.
