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:
Well it really depends because he found out about a lot of things in a lot of scientific fields actually. He is known for contributing Pascal's triangle and probability theory. He also invented an early digital calculator and a roulette machine. In the field of physics, Blaise contributed to the study of atmospheric pressure by discovering that vacuums are real and exist in the real world.
Answer:
A person who never gives up.
Explanation:
due to his passion for skateboarding he try's his never gives up until he will finally learns the trick.
The relevant equation we can use in this problem is:
h = v0 t + 0.5 g t^2
where h is height, v0 is initial velocity, t is time, g is
gravity
Since it was stated that the rock was drop, so it was free
fall and v0 = 0, therefore:
h = 0 + 0.5 * 9.81 m/s^2 * (4.9 s)^2
<span>h = 117.77 m</span>
