According to snells law
<span>n1 sin theta1 = n2 sin theta2
</span>n1 = 1.333 (water)
<span>n2 = 2.42 (diamond)</span>
it is given that theta =30 degrees so
by putting the values we have
<span>1.333 sin theta = 2.42 sin 30 </span>
<span>sin theta = (2.42/1.333) *0.5 =65.2 degree
</span>so our conclusion is
<span>the ray's angle of incidence θ1 on the diamond</span> = 65.2 degree.
hope this helps
Answer:
D
Explanation:
The decrease in potential energy is equal to the increase in kinetic energy.

It'll be my pleasure to analyze the circuit, describe my analysis in detail,
and give you a clear, precise, and accurate answer.
As soon as you let me see the circuit diagram, with values marked on
all of its components and power sources.
Answer: 4.5 billion years
Explanation:
Some of the water molecules in your drinking glass were created more than 4.5 billion years ago, according to new research.
That makes them older than the Earth, older than the solar system — even older than the sun itself.
