You didn't specify enough for me to understand clearly so if this is not your answer then I cannot help you.
Answer:
quantitative
Explanation: quantitative research is better for scientist.
Answer:
a) 7.02 W/m²
b) 1.53 J
Explanation:
Given
Amplitude of the electric wave, = 72.7 V/m
Area of flow, A = 0.0211 m²
Time taken, t = 10.3 s
To calculate the Intensity, S. We use the formula
I = E(rms)² / (cμ), where
E(rms) = E / √2 = 72.7 / √2
E(rms) = 72.7 / 1.4142
E(rms) = 51.41
c = 2.99*10^8
μ = 1.26*10^-6
I = 51.41² / [(2.99*10^8) (1.26 x 10^-6)]
I = 2642.99 / 376.74
I = 7.02 W/m²
U = energy = IAt
U = (7.02) * (0.0211) (10.3) J = 1.53 J
Answer:
13.26°
Explanation:
Using Snell's law as:
Where,
is the angle of incidence ( 35.0° )
is the angle of refraction ( ? )
is the refractive index of the refraction medium (glass, n=2.5)
is the refractive index of the incidence medium (air, n=1)
Hence,
Angle of refraction= sin⁻¹ 0.2294 = 13.26°.
<u>13.26° is the angle of the beam with the normal in the glass.</u>
