Answer : Option B) Radiative zone
Explanation : The sun consists of many zones in it. Particularly in the radiative zone, the energy is primarily transported toward the exterior side by the process of radiative diffusion and thermal conduction, rather than by convection. Energy travels through the radiation zone in the form of electromagnetic radiation as photons and energy is transformed from atom to atom.
Answer:
75 miles an hour
I hope this is correct and helps
Explanation:
F=15000/0.02
=300N
total area contact of the shoes and floor when stood in one foot=0.02m^2/2=0.01m^2
P=F/A
=300/0.01
=30 000Pa/30 000Nm^-2
in another way=15000×2
=30000N/m^2
Answer:
(a) 47.08°
(b) 47.50°
Explanation:
Angle of incidence = 78.9°
<u>For blue light :
</u>
Using Snell's law as:
Where,
Θ₁ is the angle of incidence
Θ₂ is the angle of refraction
n₂ is the refractive index for blue light which is 1.340
n₁ is the refractive index of air which is 1
So,
Angle of refraction for blue light = sin⁻¹ 0.7323 = 47.08°.
<u>For red light :
</u>
Using Snell's law as:
Where,
Θ₁ is the angle of incidence
Θ₂ is the angle of refraction
n₂ is the refractive index for red light which is 1.331
n₁ is the refractive index of air which is 1
So,
Angle of refraction for red light = sin⁻¹ 0.7373 = 47.50°.
F = 500N
S = 5m
T = 1.2s
----------------------------------
P = ?
We can use formula P = F * V, just because it was a smooth slide we can assume that average speed was V = S/T = 5 / 1.2 = 50/12
So the final answer would be:
P = F * V = 500 * 50/12
Are you sure those are correct numbers? The answer don't look nice :D
