The answer is C (They are inversely proportional). I have had this question before and C is the correct answer.
The wavelength of the light that are not reflected in the air is,
λ5= 600 nm, λ6= 500 nm, λ7=428 nm.
<u>Explanation:</u>
- For the above problem, we have the case as no<n1 and n2 < n1 .
- so we have(1<1.5;1.4<1.5)To find the wavelengths of the light that is not reflected in the air.
- Since the phase changes are not common on both the surfaces/
- we have the formula, λ=2d n²/m ( where m=1,2,3,4,5...)
- solving the problem we get,
- λ5= 600 nm, λ6= 500 nm, λ7=428 nm
- The wavelength of the light that are not reflected in the air is,
λ5= 600 nm, λ6= 500 nm, λ7=428 nm.
An object with no net force cannot experience acceleration as per Newton's Second Law. However, it is moving, so it is experiencing velocity. Since there is no acceleration, we can say that the object experiences constant velocity.
Answer:
57.1 N
Explanation:
The force of friction experienced by the sled is given by:
where
is the coefficient of friction
N is the normal reaction exerted by the snow on the sled
For a flat surface, the normal reaction is equal to the weight of the object:
N = mg
where
m = 53.0 kg is the mass of the sled
g = 9.8 m/s^2 is the acceleration of gravity
Substituting the second equation into the first one, we find:
1. In construction. When constructing roads, building
2. In Engineering, when engineering we use physics such as calculations.
3. At home
4. In industries, industries use chemicals and so on.
5. In tailoring, we use the knowledge of physics like when sowing.
6. In carpentry, we use calculations.
7. In Hospitals, we use physics we balancing
8. In Sites, we use energy.
