Answer:
d = 1.82 10⁻⁶ m = 1.82 μm
Explanation:
The diffraction phenomenon is explained by a similar equation Young's double slit equation
d sin θ = n λ
Where d is the spacing between the bars, θ is the angled diffraction, n in an integer representing the order of diffraction and λ is the wavelength of light
Let's calculate
d = n λ / sin θ
d = 1 470 10⁻⁹ /sin 15
d = 1.82 10⁻⁶ m = 1.82 μm
Answer:
A digital signal picks up noise, but is still reliable.
Explanation:
The equation for this is very simple you add then you subtract then you get the answer then you divide then it all works out for you
Answer: 1.274 N minimum force required to slide the book across the surface
Explanation:
Mass of the book = m = 0.2 kg
Normal force acting on the book,N = mg
Coefficient of friction =
= 0.65
Minimum force required to slide the book across the surface= F


1.274 N minimum force required to slide the book across the surface
Using p=v * i
p=250 * 0.8=200w = 0.2kw
power consumed in a day=0.2 *8=1.6 kwh
for one month=1.6 * 30 =48kwh
monthly bills= 48 *3 = Rs 144
