Answer
Given,
refractive index of film, n = 1.6
refractive index of air, n' = 1
angle of incidence, i = 35°
angle of refraction, r = ?
Using Snell's law
n' sin i = n sin r
1 x sin 35° = 1.6 x sin r
r = 21°
Angle of refraction is equal to 21°.
Now,
distance at which refractive angle comes out
d = 2.5 mm
α be the angle with horizontal surface and incident ray.
α = 90°-21° = 69°
t be the thickness of the film.
So,
t = 2.26 mm
Hence, the thickness of the film is equal to 2.26 mm.
160 m/s because you start off with 10 and go up by 50*3 which is 150 then add that with the begging speed to achieve 160m/s.
Answer:
The solution of the given problem is provided in the following subsection.
Explanation:
According to the question,
The change in the height of the glacier will be:
= 
= 
Change in time,
= 5 years
Now,
The rate of change will be:
= 
∵ (1 year = 12 months)
= 
= 
or,
The rate of change will be:
= 
∵ (5 years in months = 5×12 months)
= 
= 
= 
Answer:
R = 620.0 Ω +/- 5%
Explanation:
According to the standard color coding for carbon resistors, the first color represents the first digit, the second the second digit, the third is the multiplier factor (10*x), and the fourth (if existing) defines the tolerance.
In our case, we have:
Blue = 1st digit = 6
Red = 2nd digit = 2
Brown = Multiplier = 10*1 = 10
Gold = Tolerance = +/- 5%
⇒ R = 62*10 = 620.0 Ω
Tolerance = +/- 5%
Answer:
The kinetic energy is less.
The force of attraction increase
The space between the particles decrease.
Explanation:
Temperature is a measure of the kinetic energy of the particles of a substance. When you increase its temperature, also its kinetic energy increases, and vice-versa. That's why te kinetic energy is less.
In solids, the intermolecular forces are stronger than in liquids. The constituent particles are more packed also. That is the reason why the force of attraction increase and the space between the particles decrease.
