Answer:
The power consumed by the air filter is 9.936 watts
Explanation:
It is given that, the secondary coil of a step-up transformer provides the voltage that operates an electrostatic air filter.
Turn ratio of the transformer, 
Voltage of primary coil, 
Current in the secondary coil, 
The power consumed by the air filter is :
...........(1)
For a transformer, 
So, 
So, the power consumed by the air filter is 9.936 watts. Hence, this is the required solution.
Solid, Malleable, and it reflects light and heat. Those are (some) physical properties.
Answer:
λ ≈ 462 nm
Explanation:
Given:-
- The slit separation, a = 10^-5 m
- The first bright fringe occurs at, y = 0.03 m from central order
- The distance between the screen and slit, L = 0.65 m
Find:-
what is the wavelength of this light?
Solution:-
- The Young's double slit experiment gives us the relation for the interaction of a light with wavelength ( λ ) that pass through 2-slits with separation ( a ) and interfere constructively or destructively at the the screen Hence, forming an interference pattern of bright and dark fringes.
- The relation for separation ( y ) between bright fringes is related to the above mentioned parameters as given below:
y = L*n*λ / a
Where,
n: The order of fringe from central
Re-arrange for wavelength ( λ ).
- The order of first bright fringe is n = 1:
λ = y*a / L
λ = 0.03*0.00001 / 0.65
λ = 4.61538 * 10^-7 m
λ ≈ 462 nm
