Answer:
0.38°
Explanation:
= Angle
m = Number
d = Distance
n = Refractive index of liquid = 1.25
a denotes air
l denotes liquid
In the case of double split interferance we have the relation

For air

For liquid

Dividing the two equations

Wavelength ratio = 

The angular separation is 0.38°
Answer:
on and off
Explanation:
if there are switches, it can change if the electricity can get to the bulb or not. if it appears that there is no pathway for the electricity to get to the light bulb, it is of, if there is a pathway, its on
<u>Answer</u>
A. Metals A and metals B
<u>Explanation</u>
Heat transfer takes place whenever there is temperature difference. When two bodies of different temperatures are brought together, heat energy will move from one body to the other until equilibrium temperature is reached.
In our case, heat transfer will take place in all four metals.
Metal A will transfer heat to the water since it's temperature is higher than that of water.
Metal B will also transfer heat to the water since it's temperature is higher than that of water.
Metal C will get heat from the water since it's colder than the water.
Metal D will also get heat from the water since it is colder than water.
It’s C
Because C is a reflection which reflects something such as mirror
Hope this helps! •~•
If the same atoms appear on both sides, then it's balanced.
In this reaction, there are 4 Oxygens, 2 Carbons, and 2 Nitrogens on each side. So numerically, <em>it's balanced</em>. But I don't know enough chemistry to say whether the reaction is possible.
